Introduction

Barrett’s esophagus (BE) is characterized by the replacement of squamous epithelium by columnar metaplasia of the distal esophagus (>1 cm length). It is a precancerous condition, with 3%-5% of patients with BE developing esophageal adenocarcinoma (EAC) in their lifetime. EAC is one of the cancers with high morbidity and mortality (5-year survival < 20%), and its incidence has been on the rise. Studies examining the natural history of BE have demonstrated that the progression happens through a metaplasia-dysplasia-neoplasia sequence. Therefore, early detection of BE and timely management to prevent progression to EAC is crucial.

Grades of Dysplasia

The current gold standard for the diagnosis of BE neoplasia includes a high-quality endoscopic evaluation and biopsies. Biopsies should be obtained from any visible lesions (nodules, ulcers) followed by a random 4-quadrant fashion (Seattle protocol) interval of the entire length of the BE segment. It is essential to pay attention to the results of the biopsy that have been obtained since it will not only determine the surveillance interval but is crucial in planning any necessary endoscopic therapy. The possible results of the biopsy and its implications are:

• No intestinal metaplasia (IM): This would rule out Barrett’s esophagus and no further surveillance would be necessary. A recent population-based study of over 1 million patients showed a 55% and 61% reduced risk of upper gastrointestinal (UGI) cancer and deaths respectively after a negative endoscopy.¹
• Intestinal metaplasia with no dysplasia (non-dysplastic BE): Biopsies confirm presence of intestinal metaplasia in the biopsies without any evidence of dysplasia. While the rate of progression to EAC is low (0.07%-0.25%), it is not absent and thus surveillance would be indicated. Current guidelines suggest repeating an endoscopy with biopsy in 5 years if the length of BE is < 3 cm or 3 years if length of BE ≥ 3 cm.²
• Indeterminate for dysplasia (BE-IND): Biopsies confirm IM but are not able to definitively rule out dysplasia. This can be seen in about 4%-8% of the biopsies obtained. The progression rates to EAC are reported to be comparable or lower to low-grade dysplasia (LGD), so the current recommendation is to intensify acid reduction therapy and repeat endoscopy in 6 months. If repeat endoscopy downgrades to non-dysplastic, then can follow surveillance according to NDBE protocol; otherwise recommend continuing surveillance every 12 months.
• Low-grade dysplasia (BE-LGD): Biopsies confirm IM but also show tightly packed overlapping basal nuclei with hyperchromasia and irregular contours, basal stratification of nuclei, and diminished goblet and columnar cell mucus. There is significant inter-observer variability reported,³ and thus the slides must be reviewed by a second pathologist with experience in BE to confirm the findings. Once confirmed, based on risk factors such as presence of multifocal LGD, persistence of LGD, presence of visible lesions, etc., the patient can be offered Barrett’s endoscopic therapy (BET) or undergo continued surveillance. The decision of pursuing one or the other would be dependent on patient preference and shared decision-making between the patient and the provider.
• High-grade dysplasia (BE-HGD): Biopsies confirm IM with cells showing greater degree of cytologic and architectural alterations of dysplasia than LGD but without overt neoplastic features. Over 40% of the patients would progress to EAC and thus the current recommendations would be to recommend BET in these patients.⁴
• Esophageal adenocarcinoma (EAC): Biopsies demonstrate neoplasia. If the neoplastic changes are limited to the mucosa (T1a) on endoscopic ultrasound or cross-sectional imaging, then BET is suggested. If there is involvement of submucosa, then depending on the depth of invasion, absence of high-risk features (poor differentiation, lymphovascular invasion), BET can be considered as an alternative to esophagectomy.

Lesion Detection on Endoscopy

Data from large population-based studies with at least 3 years of follow-up reported that 58%-66% of EAC detected during endoscopy were diagnosed within 1 year of an index Barrett’s esophagus screening endoscopy, or post-endoscopy Barrett’s neoplasia, and were considered likely to have been missed during index endoscopy.⁵ This underscores the importance of careful and systematic endoscopic examination during an upper endoscopy.

Studies have also demonstrated that longer examination time was associated with significantly higher detection of HGD/EAC.^6,7 Careful examination of the tubular esophagus and gastroesophageal junction (GEJ) should be performed in forward and retroflexed views looking for any subtle areas of nodularity, loop distortion, variability in vascular patterns, mucosal changes concerning for dysplasia or neoplasia. Use of high-definition white light endoscopy (HD-WLE) and virtual chromoendoscopy techniques such as narrow banding imaging (NBI) or blue laser imaging (BLI) are currently recommended in the guidelines.² Spray chromoendoscopy using acetic acid can also be utilized. Another exciting development is the use of artificial intelligence (AI) in detecting and diagnosing BE associated lesions and neoplasia.
 

Barrett’s Endoscopic Therapy (BET)

Patients with visible lesions, dysplasia, or early EAC are candidates for BET (Table 1).

167527_table_web.jpg

BET involves resective and ablative modalities. The resective modalities include endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) and are the modalities of choice for nodular or raised lesions.

EMR involves endoscopic resection of abnormal mucosa using either lift-assisted technique or multi-band ligation (Figure 1).

167527_figure_web.jpg

ESD, on the other hand, involves submucosal dissection and perimeter resection of the lesion, thus providing the advantage of an en-bloc resection. In a recent randomized controlled trial (RCT) of 40 patients undergoing ESD vs EMR for HGD/EAC, ESD was better for curative resection (R0) (58%) compared with EMR (12%); however, the remission rates at 3 months were comparable with two perforations reported in the ESD group while there were no complications in the EMR group.⁸

There is an apparent learning curve when it comes to these advanced techniques, and with more experience, we are seeing comparable results for both these modalities. However, given the complexity and time required for the procedure, current practices typically involve preserving ESD for lesions > 2 cm, those having a likelihood of cancer in the superficial submucosa, or those that EMR cannot remove due to underlying fibrosis or post-EMR recurrence.

Barrett’s Refractory to Endoscopic Therapy

Failure of BET is defined as persistent columnar lined epithelium (intestinal metaplasia) with inadequate response, after adequate attempts at endoscopic ablation therapy (after resection) with at least four ablation sessions.¹³ If encountered, special attention must be given to check compliance with proton pump inhibitors (PPIs), previous incomplete resection, and presence of large hiatal hernia. If CE-IM is not achieved after multiple sessions, change of ablative modality is typically considered. In addition, careful examination for visible lesions should be performed and even if a small one is noted, this should be first resected prior to application of any ablative therapy.

Sharma_Prateek_KS_2024_web.jpg

Currently there are no guideline recommendations regarding the preference of one endoscopic modality over another or consideration of potential endoscopic or surgical fundoplication. These modalities primarily rely on technologies available at an institution and the preference of a provider based on their training and experience. Most studies indicate 1-3 sessions (~ 3 months apart) of ablative treatment before achieving CE-IM.
 

Success and Adverse Events of BET

In a recent real-world study of over 27,000 patients with dysplastic BE, 5295 underwent BET. Analysis showed that patients with HGD/EAC who had BET had a significantly lower 3-year mortality (HGD: RR, 0.59; 95%CI, 0.49-0.71; EAC: RR, 0.53; 95% CI, 0.44-0.65) compared with those who did not undergo BET. Esophageal strictures were the most common adverse event and were noted in 6.5%, followed by chest pain (1.8%), upper GI bleeding (0.47%), and esophageal perforation (0.2%).¹⁴

In general, adverse events can be divided into immediate and delayed adverse events. Immediate adverse events typically involve bleeding and perforation that can occur during or shortly after the procedure. These are reported at higher rates with resective modalities compared with ablative therapies. Standard endoscopic techniques involving coagulation grasper or clips can be used to achieve hemostasis. Endoscopic suturing devices offer the ability to contain any perforation. The need for surgical intervention is small and limited to adverse events not detected during the procedure.

Delayed adverse events such as stricture and stenosis are higher for resective modalities (up to 30%), especially when involving more significant than 75% of the esophageal circumference. Post-procedural pain/dysphagia is most common after ablative therapies. Dysphagia reported after any endoscopic therapy should be promptly evaluated, and sequential dilation until the goal esophageal lumen is achieved should be performed every 2-4 weeks.
 

Recurrences and Surveillance After BET

What is established is that recurrences can occur and may be subtle, therefore detailed endoscopic surveillance is required. In a prospective study, recurrence rates of 15%-16% for IM and 3%-5% for any dysplasia were reported, with the majority being in the first 2 years after achieving CE-IM.¹⁵ A systematic review of 21 studies looking at the location of recurrences suggested that the majority (56%) occur in the distal esophagus. Of those that occur in the esophagus, about 80% of them were in the distal 2 cm of the esophagus and only 50% of the recurrences were visible recurrences, thus reiterating the importance of meticulous examination and systematic biopsies.¹⁶

On the contrary, a recent single-center study of 217 patients who had achieved CE-IM with 5.5 years of follow-up demonstrated a 26% and 8% recurrence of IM and dysplasia, respectively. One hundred percent of the recurrence in the esophagus was reported as visible.¹⁷ Therefore, follow-up endoscopy surveillance protocol after CE-IM should still involve meticulous examination, biopsy of visible lesions, and systematic biopsies for non-visible lesions from the original BE segment, similar to those patients who have not needed BET.

Current guidelines based on expert consensus and evidence recommend surveillance after CE-IM based on original most advanced histology:²

1. LGD: 1 year, 3 years, and every 2 years after that.

2. HGD/EAC: 3 months, 6 months, 12 months, and annually after that.

There is no clear guideline on when to stop surveillance since the longest available follow-up is around 10 years, and recurrences are still detected. A potential surveillance endpoint may be based on age and comorbidities, especially those that would preclude a patient from being a candidate for BET.
 

When Should a Patient Be Referred?

BE patients with visible lesions and/or dysplastic changes in the biopsy who would require BET should be considered for referral to high-volume centers. Studies have shown higher success for CE-IM and lower rates of adverse events and recurrences in these patients managed at expert centers. The presence of a multidisciplinary team involving pathologists, surgeons, and oncologists is critical and offers a timely opportunity in case of need for a high-risk patient.

Conclusion

BE is a precursor to EAC, with rising incidence and poor 5-year survival. Endoscopic diagnosis is the gold standard and requires a high-quality examination and biopsies. Based on histopathology, a systematic surveillance and BET plan should be performed to achieve CE-IM in patients with dysplasia. Once CE-IM is achieved, regular surveillance should be performed with careful attention to recurrences and complications from the BET modalities.

While the rate of progression to EAC is low (0.07%-0.25%), it is not absent and thus surveillance would be indicated. Current guidelines suggest repeating an endoscopy with biopsy in 5 years if the length of BE is < 3 cm or 3 years if length of BE ≥ 3 cm.²
• Indeterminate for dysplasia (BE-IND): Biopsies confirm IM but are not able to definitively rule out dysplasia. This can be seen in about 4%-8% of the biopsies obtained. The progression rates to EAC are reported to be comparable or lower to low-grade dysplasia (LGD), so the current recommendation is to intensify acid reduction therapy and repeat endoscopy in 6 months. If repeat endoscopy downgrades to non-dysplastic, then can follow surveillance according to NDBE protocol; otherwise recommend continuing surveillance every 12 months.
• Low-grade dysplasia (BE-LGD): Biopsies confirm IM but also show tightly packed overlapping basal nuclei with hyperchromasia and irregular contours, basal stratification of nuclei, and diminished goblet and columnar cell mucus. There is significant inter-observer variability reported,³ and thus the slides must be reviewed by a second pathologist with experience in BE to confirm the findings. Once confirmed, based on risk factors such as presence of multifocal LGD, persistence of LGD, presence of visible lesions, etc., the patient can be offered Barrett’s endoscopic therapy (BET) or undergo continued surveillance. The decision of pursuing one or the other would be dependent on patient preference and shared decision-making between the patient and the provider.
• High-grade dysplasia (BE-HGD): Biopsies confirm IM with cells showing greater degree of cytologic and architectural alterations of dysplasia than LGD but without overt neoplastic features. Over 40% of the patients would progress to EAC and thus the current recommendations would be to recommend BET in these patients.⁴
• Esophageal adenocarcinoma (EAC): Biopsies demonstrate neoplasia. If the neoplastic changes are limited to the mucosa (T1a) on endoscopic ultrasound or cross-sectional imaging, then BET is suggested. If there is involvement of submucosa, then depending on the depth of invasion, absence of high-risk features (poor differentiation, lymphovascular invasion), BET can be considered as an alternative to esophagectomy.

Lesion Detection on Endoscopy

Data from large population-based studies with at least 3 years of follow-up reported that 58%-66% of EAC detected during endoscopy were diagnosed within 1 year of an index Barrett’s esophagus screening endoscopy, or post-endoscopy Barrett’s neoplasia, and were considered likely to have been missed during index endoscopy.⁵ This underscores the importance of careful and systematic endoscopic examination during an upper endoscopy.

Studies have also demonstrated that longer examination time was associated with significantly higher detection of HGD/EAC.^6,7 Careful examination of the tubular esophagus and gastroesophageal junction (GEJ) should be performed in forward and retroflexed views looking for any subtle areas of nodularity, loop distortion, variability in vascular patterns, mucosal changes concerning for dysplasia or neoplasia. Use of high-definition white light endoscopy (HD-WLE) and virtual chromoendoscopy techniques such as narrow banding imaging (NBI) or blue laser imaging (BLI) are currently recommended in the guidelines.² Spray chromoendoscopy using acetic acid can also be utilized. Another exciting development is the use of artificial intelligence (AI) in detecting and diagnosing BE associated lesions and neoplasia.
 

Barrett’s Endoscopic Therapy (BET)

Patients with visible lesions, dysplasia, or early EAC are candidates for BET (Table 1).

167527_table_web.jpg

BET involves resective and ablative modalities. The resective modalities include endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) and are the modalities of choice for nodular or raised lesions.

EMR involves endoscopic resection of abnormal mucosa using either lift-assisted technique or multi-band ligation (Figure 1).

167527_figure_web.jpg

ESD, on the other hand, involves submucosal dissection and perimeter resection of the lesion, thus providing the advantage of an en-bloc resection. In a recent randomized controlled trial (RCT) of 40 patients undergoing ESD vs EMR for HGD/EAC, ESD was better for curative resection (R0) (58%) compared with EMR (12%); however, the remission rates at 3 months were comparable with two perforations reported in the ESD group while there were no complications in the EMR group.⁸

There is an apparent learning curve when it comes to these advanced techniques, and with more experience, we are seeing comparable results for both these modalities. However, given the complexity and time required for the procedure, current practices typically involve preserving ESD for lesions > 2 cm, those having a likelihood of cancer in the superficial submucosa, or those that EMR cannot remove due to underlying fibrosis or post-EMR recurrence.

Barrett’s Refractory to Endoscopic Therapy

Failure of BET is defined as persistent columnar lined epithelium (intestinal metaplasia) with inadequate response, after adequate attempts at endoscopic ablation therapy (after resection) with at least four ablation sessions.¹³ If encountered, special attention must be given to check compliance with proton pump inhibitors (PPIs), previous incomplete resection, and presence of large hiatal hernia. If CE-IM is not achieved after multiple sessions, change of ablative modality is typically considered. In addition, careful examination for visible lesions should be performed and even if a small one is noted, this should be first resected prior to application of any ablative therapy.

Sharma_Prateek_KS_2024_web.jpg

Currently there are no guideline recommendations regarding the preference of one endoscopic modality over another or consideration of potential endoscopic or surgical fundoplication. These modalities primarily rely on technologies available at an institution and the preference of a provider based on their training and experience. Most studies indicate 1-3 sessions (~ 3 months apart) of ablative treatment before achieving CE-IM.
 

Success and Adverse Events of BET

In a recent real-world study of over 27,000 patients with dysplastic BE, 5295 underwent BET. Analysis showed that patients with HGD/EAC who had BET had a significantly lower 3-year mortality (HGD: RR, 0.59; 95%CI, 0.49-0.71; EAC: RR, 0.53; 95% CI, 0.44-0.65) compared with those who did not undergo BET. Esophageal strictures were the most common adverse event and were noted in 6.5%, followed by chest pain (1.8%), upper GI bleeding (0.47%), and esophageal perforation (0.2%).¹⁴

In general, adverse events can be divided into immediate and delayed adverse events. Immediate adverse events typically involve bleeding and perforation that can occur during or shortly after the procedure. These are reported at higher rates with resective modalities compared with ablative therapies. Standard endoscopic techniques involving coagulation grasper or clips can be used to achieve hemostasis. Endoscopic suturing devices offer the ability to contain any perforation. The need for surgical intervention is small and limited to adverse events not detected during the procedure.

Delayed adverse events such as stricture and stenosis are higher for resective modalities (up to 30%), especially when involving more significant than 75% of the esophageal circumference. Post-procedural pain/dysphagia is most common after ablative therapies. Dysphagia reported after any endoscopic therapy should be promptly evaluated, and sequential dilation until the goal esophageal lumen is achieved should be performed every 2-4 weeks.
 

Recurrences and Surveillance After BET

What is established is that recurrences can occur and may be subtle, therefore detailed endoscopic surveillance is required. In a prospective study, recurrence rates of 15%-16% for IM and 3%-5% for any dysplasia were reported, with the majority being in the first 2 years after achieving CE-IM.¹⁵ A systematic review of 21 studies looking at the location of recurrences suggested that the majority (56%) occur in the distal esophagus. Of those that occur in the esophagus, about 80% of them were in the distal 2 cm of the esophagus and only 50% of the recurrences were visible recurrences, thus reiterating the importance of meticulous examination and systematic biopsies.¹⁶

On the contrary, a recent single-center study of 217 patients who had achieved CE-IM with 5.5 years of follow-up demonstrated a 26% and 8% recurrence of IM and dysplasia, respectively. One hundred percent of the recurrence in the esophagus was reported as visible.¹⁷ Therefore, follow-up endoscopy surveillance protocol after CE-IM should still involve meticulous examination, biopsy of visible lesions, and systematic biopsies for non-visible lesions from the original BE segment, similar to those patients who have not needed BET.

Current guidelines based on expert consensus and evidence recommend surveillance after CE-IM based on original most advanced histology:²

1. LGD: 1 year, 3 years, and every 2 years after that.

2. HGD/EAC: 3 months, 6 months, 12 months, and annually after that.

There is no clear guideline on when to stop surveillance since the longest available follow-up is around 10 years, and recurrences are still detected. A potential surveillance endpoint may be based on age and comorbidities, especially those that would preclude a patient from being a candidate for BET.
 

When Should a Patient Be Referred?

BE patients with visible lesions and/or dysplastic changes in the biopsy who would require BET should be considered for referral to high-volume centers. Studies have shown higher success for CE-IM and lower rates of adverse events and recurrences in these patients managed at expert centers. The presence of a multidisciplinary team involving pathologists, surgeons, and oncologists is critical and offers a timely opportunity in case of need for a high-risk patient.

Conclusion

BE is a precursor to EAC, with rising incidence and poor 5-year survival. Endoscopic diagnosis is the gold standard and requires a high-quality examination and biopsies. Based on histopathology, a systematic surveillance and BET plan should be performed to achieve CE-IM in patients with dysplasia. Once CE-IM is achieved, regular surveillance should be performed with careful attention to recurrences and complications from the BET modalities.

Two of us (Parakkal Deepak and Edward L. Barnes) were part of the American Gastroenterological Association’s (AGA) Future Leaders Program (FLP) class of 2022-2023, and our mentor was Aasma Shaukat. We were invited to share our experiences as participants in the FLP and its impact in our careers.

Deepak_Parakkal_MO_web.jpg

Why Was the Future Leaders Program Conceived?

To understand this, one must first understand that the AGA, like all other GI professional organizations, relies on volunteer leaders to develop its long-term vision and execute this through strategic initiatives and programs. Over time, both the AGA and the field of GI have grown in both size and complexity, which led to the vision of developing a pipeline of leaders who can understand the future challenges facing our field and understand the governance structure of the AGA to help lead it to face these challenges effectively.

Barnes_Edward_L_NC_2023_web.jpg

The AGA FLP was thus conceived and launched in 2014-2015 by the founding chairs, Byron Cryer, MD, who is a professor of medicine and associate dean for faculty diversity at University of Texas Southwestern Medical School and Suzanne Rose, MD, MSEd, AGAF, who is a professor of medicine and senior vice dean for medical education at Perelman School of Medicine at the University of Pennsylvania. They envisioned a leadership pathway that would position early career GIs on a track to positively affect the AGA and the field of GI.
 

How Does One Apply for the Program?

Our FLP cohort applications were invited in October of 2021 and mentees accepted into the program in November 2021. The application process is competitive – applicants are encouraged to detail why they feel they would benefit from the FLP, what existing skillsets they have that can be further enhanced through the program, and what their long-term vision is for their growth as leaders, both within their institution and within the AGA. This is further accompanied by letters of support from their divisional chiefs and other key supervisors within the division who are intimately aware of their leadership potential and career trajectory. This process identified 18 future leaders for our class of 2022-2023.

Shaukat_Aasma_NY_web.jpg

What Is Involved?

Following acceptance into the AGA Future Leaders Program, we embarked on a series of virtual and in-person meetings with our mentorship triads (one mentor and two mentees) and other mentorship teams over the 18-month program (see Figure). These meetings covered highly focused topics ranging from the role of advocacy in leadership to negotiation and developing a business plan, with ample opportunities for individually tailored mentorship within the mentorship triads.

167890_Figure 1_web.jpg

We also completed personality assessments that helped us understand our strengths and areas of improvement, and ways to use the information to hone our leadership styles.

A large portion of programming and the mentorship experience during the AGA Future Leaders Program is focused on a leadership project that is aimed at addressing a societal driver of interest for the AGA. Examples of these societal drivers of interest include maximizing the role of women in gastroenterology, the role of artificial intelligence in gastroenterology, burnout, and the impact of climate change on gastroenterology. Mentorship triads propose novel methods for addressing these critical issues, outlining the roles that the AGA and other stakeholders may embrace to address these anticipated growing challenges head on.

Our mentorship triad was asked to address the issue of ending disparities within gastroenterology. Given our research and clinical interest in inflammatory bowel disease (IBD), we immediately recognized an opportunity to evaluate and potentially offer solutions for the geographic disparities that exist in the field of IBD. These disparities affect access to care for patients with Crohn’s disease and ulcerative colitis, leading to delays in diagnosis and ultimately effective therapy decisions.

In addition to developing a proposal for the AGA to expand access to care to major IBD centers in rural areas where these disparities exist, we also initiated an examination of geographic disparities in our own multidisciplinary IBD centers (abstract accepted for presentation at Digestive Diseases Week 2024). This allowed us to expand our respective research footprints at our institutions, utilizing new methods of geocoding to directly measure factors affecting clinical outcomes in IBD. Given our in-depth evaluation of this topic as part of our Future Leaders Program training, at the suggestion of our mentor, our mentorship triad also published a commentary on geographic disparities in the Diversity, Equity, and Inclusion sections of Gastroenterology and Clinical Gastroenterology and Hepatology.^{1, 2}

Impact on the Field and Our Careers

Our mentorship triad had the unique experience of having a mentor who had previously participated in the Future Leaders Program as a mentee. As the Future Leaders Program has now enrolled 72 participants, these occasions will likely become more frequent, given the opportunities for career development and growth within the AGA (and our field) that are available after participating in the Future Leaders Program.

To have a mentor with this insight of having been a mentee in the program was invaluable, given her direct experience and understanding of the growth opportunities available, and opportunities to maximize participation in the Future Leaders Program. Additionally, as evidenced by Dr. Shaukat’s recommendations to grow our initial assignment into published commentaries, need statements for our field, and ultimately growing research projects, her keen insights as a mentor were a critical component of our individual growth in the program and the success of our mentorship triad. We benefited from networking with peers and learning about their work, which can lead to future collaborations. We had access to the highly accomplished mentors from diverse settings and learned models of leadership, while developing skills to foster our own leadership style.

In terms of programmatic impact, more than 90% of FLP alumni are serving in AGA leadership on committees, task forces, editorial boards, and councils. What is also important is the impact of content developed by mentee-mentor triads during the FLP cohorts over time. More than 700 GIs have benefited from online leadership development content created by the FLP. Based on our experience, we highly recommend all early career GI physicians to apply!

As gastroenterologists, we spend innumerable years in medical training with an abrupt and significant increase in our earning potential upon beginning practice. The majority of us also carry a sizeable amount of student loan debt. This combination results in a unique situation that can make us hesitant about how best to set ourselves up financially while also making us vulnerable to potentially predatory financial practices.

Although your initial steps to achieve financial wellness and build wealth can be obtained on your own with some education, a financial adviser becomes indispensable when you have significant assets, a high income, complex finances, and/or are experiencing a major life change. Additionally, as there are so many avenues to invest and grow your capital, a financial adviser can assist in designing a portfolio to best accomplish specific monetary goals. Studies have demonstrated that those working with a financial adviser reduce their single-stock risk and have more significant increase in portfolio value, reducing the total cost associated with their investments’ management.¹ Those working with a financial adviser will also net up to a 3% larger annual return, compared with a standard baseline investment plan.^2,3

Luthra_Anjuli_FL_web.jpg

Based on this information, it may appear that working with a personal financial adviser would be a no-brainer. Unfortunately, there is a caveat: There is no legal regulation regarding who can use the title “financial adviser.” It is therefore crucial to be aware of common practices and terminology to best help you identify a reputable financial adviser and reduce your risk of excessive fees or financial loss. This is also a highly personal decision and your search should first begin with understanding why you are looking for an adviser, as this will determine the appropriate type of service to look for.
 

Types of Advisers

A certified financial planner (CFP) is an expert in estate planning, taxes, retirement saving, and financial planning who has a formal designation by the Certified Financial Planner Board of Standards Inc.⁴ They must undergo stringent licensing examinations following a 3-year course with required continuing education to maintain their credentials. CFPs are fiduciaries, meaning they must make financial decisions in your best interest, even if they may make less money with that product or investment strategy. In other words, they are beholden to give honest, impartial recommendations to their clients, and may face sanctions by the CFP Board if found to violate its Code of Ethics and Standards of Conduct, which includes failure to act in a fiduciary duty.⁵

CFPs evaluate your total financial picture, such as investments, insurance policies, and overall current financial position, to develop a comprehensive strategy that will successfully guide you to your financial goal. There are many individuals who may refer to themselves as financial planners without having the CFP designation; while they may offer similar services as above, they will not be required to act as a fiduciary. Hence, it is important to do your due diligence and verify they hold this certification via the CFP Board website: www.cfp.net/verify-a-cfp-professional.

An investment adviser is a legal term from the U.S. Securities and Exchange Commission (SEC) and the Financial Industry Regulatory Authority (FINRA) referring to an individual who provides recommendations and analyses for financial securities such as stock. Both of these agencies ensure investment advisers adhere to regulatory requirements designed to protect client investers. Similar to CFPs, they are held to a fiduciary standard, and their firm is required to register with the SEC or the state of practice based on the amount of assets under management.⁶

An individual investment adviser must also register with their state as an Investment Adviser Representative (IAR), the distinctive term referring to an individual as opposed to an investment advising firm. Investment advisers are required to pass the extensive Series 65, Uniform Investment Advisor Law Exam, or equivalent, by states requiring licensure.⁷ They can guide you on the selection of particular investments and portfolio management based on a discussion with you regarding your current financial standing and what fiscal ambitions you wish to achieve.

A financial adviser provides direction on a multitude of financially related topics such as investing, tax laws, and life insurance with the goal to help you reach specific financial objectives. However, this term is often used quite ubiquitously given the lack of formal regulation of the title. Essentially, those with varying types of educational background can give themselves the title of financial adviser.

If a financial adviser buys or sells financial securities such as stocks or bonds, then they must be registered as a licensed broker with the SEC and IAR and pass the Series 6 or Series 7 exam. Unlike CFPs and investment advisers, a financial adviser (if also a licensed broker) is not required to be a fiduciary, and instead works under the suitability standard.⁸ Suitability requires that financial recommendations made by the adviser are appropriate but not necessarily the best for the client. In fact, these recommendations do not even have to be the most suitable. This is where conflicts of interest can arise with the adviser recommending products and securities that best compensate them while not serving the best return on investment for you.

Making the search for a financial adviser more complex, an individual can be a combination of any of the above, pending the appropriate licensing. For example, a CFP can also be an asset manager and thus hold the title of a financial adviser and/or IAR. A financial adviser may also not directly manage your assets if they have a partnership with a third party or another licensed individual. Questions to ask of your potential financial adviser should therefore include the following:

• What licensure and related education do you have?
• What is your particular area of expertise?
• How long have you been in practice?
• How will you be managing my assets?

Financial Adviser Fee Schedules

Prior to working with a financial adviser, you must also inquire about their fee structure. There are two kinds of fee schedules used by financial advisers: fee-only and fee-based.

Fee-only advisers receive payment solely for the services they provide. They do not collect commissions from third parties providing the recommended products. There is variability in how this type of payment schedule is structured, encompassing flat fees, hourly rates, or the adviser charging a retainer. The Table below compares the types of fee-only structures and range of charges based on 2023 rates.⁹ Of note, fee-only advisers serve as fiduciaries.¹⁰

Fee-based financial advisers receive payment for services but may also receive commission on specific products they sell to you.⁹ Most, if not all, financial experts recommend avoiding advisers using commission-based charges given the potential conflict of interest: How can one be absolutely sure this recommended financial product is best for you, knowing your adviser has a financial stake in said item?

167871_table_web.jpg

In addition to charging the fees above, your financial adviser, if they are actively managing your investment portfolio, will also charge an assets under management (AUM) fee. This is a percentage of the dollar amount within your portfolio. For example, if your adviser charges a 1% AUM rate for your account totaling $100,000, this equates to a $1,000 fee in that calendar year. AUM fees typically decrease as the size of your portfolio increases. As seen in the Table, there is a wide range of the average AUM rate (0.5%–2%); however, an AUM fee approaching 2% is unnecessarily high and consumes a significant portion of your portfolio. Thus, it is recommended to look for a money manager with an approximate 1% AUM fee.

Many of us delay or avoid working with a financial adviser due to the potential perceived risks of having poor portfolio management from an adviser not working in our best interest, along with the concern for excessive fees. While anyone can invest in an Exchange Traded Fund or Index Fund, we can lose on not seeking a financial adviser’s expertise to increase our asset growth and fund of financial knowledge.

As gastroenterologists, we spend innumerable years in medical training with an abrupt and significant increase in our earning potential upon beginning practice. The majority of us also carry a sizeable amount of student loan debt. This combination results in a unique situation that can make us hesitant about how best to set ourselves up financially while also making us vulnerable to potentially predatory financial practices.

Although your initial steps to achieve financial wellness and build wealth can be obtained on your own with some education, a financial adviser becomes indispensable when you have significant assets, a high income, complex finances, and/or are experiencing a major life change. Additionally, as there are so many avenues to invest and grow your capital, a financial adviser can assist in designing a portfolio to best accomplish specific monetary goals. Studies have demonstrated that those working with a financial adviser reduce their single-stock risk and have more significant increase in portfolio value, reducing the total cost associated with their investments’ management.¹ Those working with a financial adviser will also net up to a 3% larger annual return, compared with a standard baseline investment plan.^2,3

Based on this information, it may appear that working with a personal financial adviser would be a no-brainer. Unfortunately, there is a caveat: There is no legal regulation regarding who can use the title “financial adviser.” It is therefore crucial to be aware of common practices and terminology to best help you identify a reputable financial adviser and reduce your risk of excessive fees or financial loss. This is also a highly personal decision and your search should first begin with understanding why you are looking for an adviser, as this will determine the appropriate type of service to look for.
 

Types of Advisers

A certified financial planner (CFP) is an expert in estate planning, taxes, retirement saving, and financial planning who has a formal designation by the Certified Financial Planner Board of Standards Inc.⁴ They must undergo stringent licensing examinations following a 3-year course with required continuing education to maintain their credentials. CFPs are fiduciaries, meaning they must make financial decisions in your best interest, even if they may make less money with that product or investment strategy. In other words, they are beholden to give honest, impartial recommendations to their clients, and may face sanctions by the CFP Board if found to violate its Code of Ethics and Standards of Conduct, which includes failure to act in a fiduciary duty.⁵

CFPs evaluate your total financial picture, such as investments, insurance policies, and overall current financial position, to develop a comprehensive strategy that will successfully guide you to your financial goal. There are many individuals who may refer to themselves as financial planners without having the CFP designation; while they may offer similar services as above, they will not be required to act as a fiduciary. Hence, it is important to do your due diligence and verify they hold this certification via the CFP Board website: www.cfp.net/verify-a-cfp-professional.

An investment adviser is a legal term from the U.S. Securities and Exchange Commission (SEC) and the Financial Industry Regulatory Authority (FINRA) referring to an individual who provides recommendations and analyses for financial securities such as stock. Both of these agencies ensure investment advisers adhere to regulatory requirements designed to protect client investers. Similar to CFPs, they are held to a fiduciary standard, and their firm is required to register with the SEC or the state of practice based on the amount of assets under management.⁶

An individual investment adviser must also register with their state as an Investment Adviser Representative (IAR), the distinctive term referring to an individual as opposed to an investment advising firm. Investment advisers are required to pass the extensive Series 65, Uniform Investment Advisor Law Exam, or equivalent, by states requiring licensure.⁷ They can guide you on the selection of particular investments and portfolio management based on a discussion with you regarding your current financial standing and what fiscal ambitions you wish to achieve.

A financial adviser provides direction on a multitude of financially related topics such as investing, tax laws, and life insurance with the goal to help you reach specific financial objectives. However, this term is often used quite ubiquitously given the lack of formal regulation of the title. Essentially, those with varying types of educational background can give themselves the title of financial adviser.

If a financial adviser buys or sells financial securities such as stocks or bonds, then they must be registered as a licensed broker with the SEC and IAR and pass the Series 6 or Series 7 exam. Unlike CFPs and investment advisers, a financial adviser (if also a licensed broker) is not required to be a fiduciary, and instead works under the suitability standard.⁸ Suitability requires that financial recommendations made by the adviser are appropriate but not necessarily the best for the client. In fact, these recommendations do not even have to be the most suitable. This is where conflicts of interest can arise with the adviser recommending products and securities that best compensate them while not serving the best return on investment for you.

Making the search for a financial adviser more complex, an individual can be a combination of any of the above, pending the appropriate licensing. For example, a CFP can also be an asset manager and thus hold the title of a financial adviser and/or IAR. A financial adviser may also not directly manage your assets if they have a partnership with a third party or another licensed individual. Questions to ask of your potential financial adviser should therefore include the following:

• What licensure and related education do you have?
• What is your particular area of expertise?
• How long have you been in practice?
• How will you be managing my assets?

Financial Adviser Fee Schedules

Prior to working with a financial adviser, you must also inquire about their fee structure. There are two kinds of fee schedules used by financial advisers: fee-only and fee-based.

Fee-only advisers receive payment solely for the services they provide. They do not collect commissions from third parties providing the recommended products. There is variability in how this type of payment schedule is structured, encompassing flat fees, hourly rates, or the adviser charging a retainer. The Table below compares the types of fee-only structures and range of charges based on 2023 rates.⁹ Of note, fee-only advisers serve as fiduciaries.¹⁰

Fee-based financial advisers receive payment for services but may also receive commission on specific products they sell to you.⁹ Most, if not all, financial experts recommend avoiding advisers using commission-based charges given the potential conflict of interest: How can one be absolutely sure this recommended financial product is best for you, knowing your adviser has a financial stake in said item?

167871_table_web.jpg

In addition to charging the fees above, your financial adviser, if they are actively managing your investment portfolio, will also charge an assets under management (AUM) fee. This is a percentage of the dollar amount within your portfolio. For example, if your adviser charges a 1% AUM rate for your account totaling $100,000, this equates to a $1,000 fee in that calendar year. AUM fees typically decrease as the size of your portfolio increases. As seen in the Table, there is a wide range of the average AUM rate (0.5%–2%); however, an AUM fee approaching 2% is unnecessarily high and consumes a significant portion of your portfolio. Thus, it is recommended to look for a money manager with an approximate 1% AUM fee.

Many of us delay or avoid working with a financial adviser due to the potential perceived risks of having poor portfolio management from an adviser not working in our best interest, along with the concern for excessive fees. While anyone can invest in an Exchange Traded Fund or Index Fund, we can lose on not seeking a financial adviser’s expertise to increase our asset growth and fund of financial knowledge. In many ways, it is how we counsel our patients. While they can seek medical information on their own, their best care is under the guidance of an expert: a healthcare professional. That being said, personal finance is indeed personal, so I hope this guide helps facilitate your search and increase your financial wellness.

Academic medicine plays a crucial role at the crossroads of medical practice, education, and research, influencing the future landscape of healthcare. Many physicians aspire to pursue and sustain a career in academic medicine to contribute to the advancement of medical knowledge, enhance patient care, and influence the trajectory of the medical field. Opting for a career in academic medicine can offer benefits such as increased autonomy and scheduling flexibility, which can significantly improve the quality of life. In addition, engagement in scholarly activities and working in a dynamic environment with continuous learning opportunities can help mitigate burnout.

However, embarking on an academic career can be daunting for junior faculty members who face the challenge of providing clinical care while excelling in research and dedicating time to mentorship and teaching trainees. According to a report by the Association of American Medical Colleges, 38% of physicians leave academic medicine within a decade of obtaining a faculty position. Barriers to promotion and retention within academic medicine include ineffective mentorship, unclear or inconsistent promotion criteria, and disparities in gender/ethnic representation.

Interview with Sophie Balzora, MD

Dr. Balzora is a professor of medicine at NYU Grossman School of Medicine and a practicing gastroenterologist specializing in the care of patients with inflammatory bowel disease at NYU Langone Health. She serves as the American College of Gastroenterology’s Diversity, Equity, and Inclusion Committee Chair, on the Advisory Board of ACG’s Leadership, Ethics, and Equity (LE&E) Center, and is president and cofounder of the Association of Black Gastroenterologists and Hepatologists (ABGH). Dr. Balzora was promoted to full professor 11 years after graduating from fellowship.

Balzora_Sophie_NY_web.jpg

What would you identify as some of the most important factors that led to your success in achieving a promotion to professor of medicine?

Surround yourself with individuals whose professional and personal priorities align with yours. To achieve this, it is essential to gain an understanding of what is important to you, what you envision your success to look like, and establish a timeline to achieve it. The concept of personal success and how to best achieve it will absolutely change as you grow, and that is okay and expected. Connecting with those outside of your clinical interests, at other institutions, and even outside of the medical field, can help you achieve these goals and better shape how you see your career unfolding and how you want it to look.

Historically, the proportion of physicians who achieve professorship is lower among women compared with men. What do you believe are some of the barriers involved in this, and how would you counsel women who are interested in pursuing the rank of professor?

Systemic gender bias and discrimination, over-mentorship and under-sponsorship, inconsistent parental leave, and delayed parenthood are a few of the factors that contribute to the observed disparities in academic rank. Predictably, for women from underrepresented backgrounds in medicine, the chasm grows.

What has helped me most is to keep my eyes on the prize, and to recognize that the prize is different for everyone. It’s important not to make direct comparisons to any other individual, because they are not you. Harness what makes you different and drown out the naysayers — the “we’ve never seen this done before” camp, the “it’s too soon [for someone like you] to go up for promotion” folks. While these voices are sometimes well intentioned, they can distract you from your goals and ambitions because they are rooted in bias and adherence to traditional expectations. To do something new, and to change the game, requires going against the grain and utilizing your skills and talents to achieve what you want to achieve in a way that works for you.
 

What are some practical tips you have for junior gastroenterologists to track their promotion in academia?

• Keep your curriculum vitae (CV) up to date and formatted to your institutional guidelines. Ensure that you document your academic activities, even if it doesn’t seem important in the moment. When it’s time to submit that promotion portfolio, you want to be ready and organized.
• Remember: “No” is a full sentence, and saying it takes practice and time and confidence. It is a skill I still struggle to adopt at times, but it’s important to recognize the power of no, for it opens opportunities to say yes to other things.
• Lift as you climb — a critical part of changing the status quo is fostering the future of those underrepresented in medicine. A professional goal of mine that keeps me steady and passionate is to create supporting and enriching systemic and institutional changes that work to dismantle the obstacles perpetuating disparities in academic rank for women and those underrepresented in medicine. Discovering your “why” is a complex, difficult, and rewarding journey.

Interview with Mark Schattner, MD, AGAF

Dr. Schattner is a professor of clinical medicine at Weill Cornell College of Medicine and chief of the gastroenterology, hepatology, and nutrition service at Memorial Sloan Kettering Cancer Center, both in New York. He is a former president of the New York Society for Gastrointestinal Endoscopy and a fellow of the AGA and ASGE.

Schattner_Mark_NY_web.jpg

In your role as chief, you serve as a mentor for early career gastroenterologists for pursuing career promotion. What advice do you have for achieving this?

Promoting junior faculty is one of the prime responsibilities of a service chief. Generally, the early steps of promotion are straightforward, with criteria becoming more stringent as you progress. I think it is critical to understand the criteria used by promotion committees and to be aware of the various available tracks. I believe every meeting a junior faculty member has with their service chief should include, at the least, a brief check-in on where they are in the promotion process and plans (both short term and long term) to move forward. Successful promotion is facilitated when done upon a solid foundation of production and accomplishment. It is very challenging or even impossible when trying to piece together a package from discordant activities.

Most institutions require or encourage academic involvement at both national and international levels for career promotion. Do you have advice for junior faculty about how to achieve this type of recognition or experience?

The easiest place to start is with regional professional societies. Active involvement in these local societies fosters valuable networking and lays the groundwork for involvement at the national or international level. I would strongly encourage junior faculty to seek opportunities for a leadership position at any level in these societies and move up the ladder as their career matures. This is also a very good avenue to network and get invited to join collaborative research projects, which can be a fruitful means to enhance your academic productivity.

In your opinion, what factors are likely to hinder or delay an individual’s promotion?

I think it is crucial to consider the career track you are on. If you are very clinically productive and love to teach, that is completely appropriate, and most institutions will recognize the value of that and promote you along a clinical-educator tract. On the other hand, if you have a passion for research and can successfully lead research and compete for grants, then you would move along a traditional tenure track. It is also critical to think ahead, know the criteria on which you will be judged, and incorporate that into your practice early. Trying to scramble to enhance your CV in a short time just for promotion will likely prove ineffective.

Do you have advice for junior faculty who have families about how to manage career goals but also prioritize time with family?

There is no one-size-fits-all approach to this. I think this requires a lot of shared decision-making with your family. Compromise will undoubtedly be required. For example, I always chose to live in close proximity to my workplace, eliminating any commuting time. This choice really allowed me spend time with my family.

In conclusion, a career in academic medicine presents both opportunities and challenges. A successful academic career, and achieving promotion to the rank of professor of medicine, requires a combination of factors including understanding institution-specific criteria for promotion, proactive engagement at the regional and national level, and envisioning your career goals and creating a timeline to achieve them. There are challenges to promotion, including navigating systemic biases and balancing career goals with family commitments, which also requires consideration and open communication. Ultimately, we hope these insights provide valuable guidance and advice for junior faculty who are navigating this complex environment of academic medicine and are motivated toward achieving professional fulfillment and satisfaction in their careers.

• Remember: “No” is a full sentence, and saying it takes practice and time and confidence. It is a skill I still struggle to adopt at times, but it’s important to recognize the power of no, for it opens opportunities to say yes to other things.
• Lift as you climb — a critical part of changing the status quo is fostering the future of those underrepresented in medicine. A professional goal of mine that keeps me steady and passionate is to create supporting and enriching systemic and institutional changes that work to dismantle the obstacles perpetuating disparities in academic rank for women and those underrepresented in medicine. Discovering your “why” is a complex, difficult, and rewarding journey.

Interview with Mark Schattner, MD, AGAF

Dr. Schattner is a professor of clinical medicine at Weill Cornell College of Medicine and chief of the gastroenterology, hepatology, and nutrition service at Memorial Sloan Kettering Cancer Center, both in New York. He is a former president of the New York Society for Gastrointestinal Endoscopy and a fellow of the AGA and ASGE.

In your role as chief, you serve as a mentor for early career gastroenterologists for pursuing career promotion. What advice do you have for achieving this?

Promoting junior faculty is one of the prime responsibilities of a service chief. Generally, the early steps of promotion are straightforward, with criteria becoming more stringent as you progress. I think it is critical to understand the criteria used by promotion committees and to be aware of the various available tracks. I believe every meeting a junior faculty member has with their service chief should include, at the least, a brief check-in on where they are in the promotion process and plans (both short term and long term) to move forward. Successful promotion is facilitated when done upon a solid foundation of production and accomplishment. It is very challenging or even impossible when trying to piece together a package from discordant activities.

Most institutions require or encourage academic involvement at both national and international levels for career promotion. Do you have advice for junior faculty about how to achieve this type of recognition or experience?

The easiest place to start is with regional professional societies. Active involvement in these local societies fosters valuable networking and lays the groundwork for involvement at the national or international level. I would strongly encourage junior faculty to seek opportunities for a leadership position at any level in these societies and move up the ladder as their career matures. This is also a very good avenue to network and get invited to join collaborative research projects, which can be a fruitful means to enhance your academic productivity.

In your opinion, what factors are likely to hinder or delay an individual’s promotion?

I think it is crucial to consider the career track you are on. If you are very clinically productive and love to teach, that is completely appropriate, and most institutions will recognize the value of that and promote you along a clinical-educator tract. On the other hand, if you have a passion for research and can successfully lead research and compete for grants, then you would move along a traditional tenure track. It is also critical to think ahead, know the criteria on which you will be judged, and incorporate that into your practice early. Trying to scramble to enhance your CV in a short time just for promotion will likely prove ineffective.

Do you have advice for junior faculty who have families about how to manage career goals but also prioritize time with family?

There is no one-size-fits-all approach to this. I think this requires a lot of shared decision-making with your family. Compromise will undoubtedly be required. For example, I always chose to live in close proximity to my workplace, eliminating any commuting time. This choice really allowed me spend time with my family.

In conclusion, a career in academic medicine presents both opportunities and challenges. A successful academic career, and achieving promotion to the rank of professor of medicine, requires a combination of factors including understanding institution-specific criteria for promotion, proactive engagement at the regional and national level, and envisioning your career goals and creating a timeline to achieve them. There are challenges to promotion, including navigating systemic biases and balancing career goals with family commitments, which also requires consideration and open communication. Ultimately, we hope these insights provide valuable guidance and advice for junior faculty who are navigating this complex environment of academic medicine and are motivated toward achieving professional fulfillment and satisfaction in their careers.

Academic medicine plays a crucial role at the crossroads of medical practice, education, and research, influencing the future landscape of healthcare. Many physicians aspire to pursue and sustain a career in academic medicine to contribute to the advancement of medical knowledge, enhance patient care, and influence the trajectory of the medical field. Opting for a career in academic medicine can offer benefits such as increased autonomy and scheduling flexibility, which can significantly improve the quality of life. In addition, engagement in scholarly activities and working in a dynamic environment with continuous learning opportunities can help mitigate burnout.

However, embarking on an academic career can be daunting for junior faculty members who face the challenge of providing clinical care while excelling in research and dedicating time to mentorship and teaching trainees. According to a report by the Association of American Medical Colleges, 38% of physicians leave academic medicine within a decade of obtaining a faculty position. Barriers to promotion and retention within academic medicine include ineffective mentorship, unclear or inconsistent promotion criteria, and disparities in gender/ethnic representation.

What would you identify as some of the most important factors that led to your success in achieving a promotion to professor of medicine?

Surround yourself with individuals whose professional and personal priorities align with yours. To achieve this, it is essential to gain an understanding of what is important to you, what you envision your success to look like, and establish a timeline to achieve it. The concept of personal success and how to best achieve it will absolutely change as you grow, and that is okay and expected. Connecting with those outside of your clinical interests, at other institutions, and even outside of the medical field, can help you achieve these goals and better shape how you see your career unfolding and how you want it to look.

Historically, the proportion of physicians who achieve professorship is lower among women compared with men. What do you believe are some of the barriers involved in this, and how would you counsel women who are interested in pursuing the rank of professor?

Systemic gender bias and discrimination, over-mentorship and under-sponsorship, inconsistent parental leave, and delayed parenthood are a few of the factors that contribute to the observed disparities in academic rank. Predictably, for women from underrepresented backgrounds in medicine, the chasm grows.

What has helped me most is to keep my eyes on the prize, and to recognize that the prize is different for everyone. It’s important not to make direct comparisons to any other individual, because they are not you. Harness what makes you different and drown out the naysayers — the “we’ve never seen this done before” camp, the “it’s too soon [for someone like you] to go up for promotion” folks. While these voices are sometimes well intentioned, they can distract you from your goals and ambitions because they are rooted in bias and adherence to traditional expectations. To do something new, and to change the game, requires going against the grain and utilizing your skills and talents to achieve what you want to achieve in a way that works for you.

Pelvic floor dysfunction (PFD) represents a spectrum of symptoms involving sensory and emptying abnormalities of the bowel and bladder and pelvic organ prolapse. The pelvic floor refers to a group of muscles that spans the pelvic outlet, providing support to the pelvic organs and coordinating constrictor mechanisms to control urination and defecation. Symptoms reported by patients experiencing PFD include involuntary loss of stool or urine, incomplete emptying of the bowel and bladder, a sensation of fullness, bulging in the vagina, and sexual dysfunction.¹

As such, symptoms related to PFD are very common concerns raised by patients to their gastroenterologists. Data from the National Health and Nutrition Examination Survey show that 23.7% of women over the age of 20 had at least one symptom of PFD.² Unfortunately, patients experiencing pelvic floor dysfunction often are hesitant to seek care because of embarrassment or perception that limited treatment options exist for their symptoms.
 

Pelvic Floor Anatomy

Regions of the pelvis are often referred to by anatomic compartment: anterior (bladder and urethra), middle (vagina and uterus or prostate), and posterior (colon, rectum, and anal canal). Supporting these compartments is the levator ani, a muscle group that is used synonymously with the term “pelvic diaphragm.”

Khan_ Ayesha_TX_web.jpg

Continence of stool is provided by the anal sphincter muscles and the puborectalis muscle, which wraps around the posterior aspect of the anorectal canal. Damage to the musculature or sensory perception to this area may result in fecal incontinence. Defecation is a coordinated process during which the abdominal and rectal muscles contract, while the anal sphincter muscles and puborectalis simultaneously relax. A disturbance in neuromuscular coordination (dyssynergic defecation) or structural pathology such as pelvic organ prolapse may lead to obstructed defecation.

PFD is thought to be a result of one or more insults to the pelvic floor such as chronic straining, childbirth, iatrogenic injury, or systemic disease such as diabetes.³
 

Evaluation of PFD Symptoms

Patients presenting with suspected PFD necessitate a comprehensive interdisciplinary assessment. In addition to obtaining a medical, surgical, and obstetric history, details about symptoms and lifestyle should include toileting habits, diet, and physical activity. The Pelvic Floor Distress Inventory (PFDI-20) is a commonly used tool that can be employed in the clinical setting.⁴

A pelvic exam can reveal pelvic organ prolapse and other mucosal pathology. The Pelvic Organ Prolapse Quantification System (POP-Q) is a widely used classification system for describing pelvic organ prolapse.⁵ Protrusion of the rectal wall into the vagina is referred to as a rectocele, while prolapse of small bowel into the upper posterior wall of the vagina is called an enterocele. While the finding of a rectocele on exam is common in parous women and may not cause any symptoms, a larger rectocele may cause a sensation of incomplete evacuation of stool.

Menon_ Raakhi_TX_web.jpg

Initial Management

A stepwise approach to the management of PFD can allow many patients to be effectively treated without the need for surgical intervention. For patients reporting liquid stool consistency, the evaluation should pivot toward the workup and management of diarrhea, which can easily overwhelm continence mechanisms and cause fecal incontinence. Fiber supplementation to normalize stool consistency is considered first-line therapy for patients presenting with both fecal incontinence and obstructed defecation. Other tools for fecal incontinence include avoiding foods that trigger diarrhea and use of loperamide.⁶ For patients with obstructed defecation, a trial of laxatives can be followed by a prescription agent if needed, such as a secretagogue or prokinetic.⁷

Vaginal splinting is a technique that can be used in patients with rectocele, whereby a finger is inserted into the vagina and pressure is applied on the posterior vaginal wall toward the rectum. Reducing the rectocele can facilitate emptying stool from the rectum and prevent leakage of retained stool.⁸ Similarly, use of rectal irrigation enemas can also help clear retained stool.

Pelvic floor physical therapists examine the strength, coordination, and tone of the pelvic floor muscles. When hypertonic musculature is present, manual interventions may be performed including trigger point release, myofascial release, and dry needling.⁹ When hypotonic musculature or dyssynergia is present, strengthening and neuromuscular re-education are recommended. Biofeedback can be administered via surface electromyography and/or balloon training to improve rectal sensitivity. Proper defecation techniques, including positioning, breathing, and behavioral modifications, improve clinical outcomes.

Allen_Lindsay_TX_web.jpg

Diagnostic Testing

For patients who do not improve with conservative management, further testing is recommended to characterize the underlying pathology. Typically, anorectal manometry (ARM) is performed in conjunction with the balloon expulsion test and imaging. Each modality has its strengths and limitations (see Table 1).

167838 Table_web.jpg

ARM allows for the assessment of rectal sensation and recto-anal pressures and coordination.¹⁰

Dynamic imaging, by barium defecography under fluoroscopy or MRI, captures anatomy at rest and with simulated defecation to identify pelvic organ prolapse, compartmental defects, and organ mobility.¹¹ Endoanal ultrasonography is considered in patients experiencing fecal incontinence to evaluate the integrity of the anal sphincter muscles.
 

Minimally Invasive Procedures and Surgical Options for PFD

Functional abnormalities such as dyssynergia often coexist with structural abnormalities. Because structural abnormalities are commonly found in asymptomatic patients, noninvasive functional therapy, such as pelvic floor physical therapy and anorectal biofeedback, are preferred prior to surgical repair of a structural finding. For patients with fecal incontinence, sacral nerve stimulation (SNS) has emerged as a preferred therapy due to demonstrated efficacy in symptom improvement.¹² Sphincteroplasty is reserved for those with acute sphincter injury or failure of SNS.

Corning_Brooke_TX_web.jpg

In patients with findings of intussusception, prolapse, or rectocele that have not responded to conservative therapy, referral for surgical repair may be considered. While the specific surgical approach will depend on many factors, the goal is typically excision and/or suspension of rectal tissue and reinforcement of the rectovaginal septum.

Pelvic floor disorders and related gastrointestinal complaints are very common, and likely to increase with increasing longevity and an aging population. It is critical that we are equipped with the available knowledge and tools to provide these patients with optimal care.

Pelvic floor dysfunction (PFD) represents a spectrum of symptoms involving sensory and emptying abnormalities of the bowel and bladder and pelvic organ prolapse. The pelvic floor refers to a group of muscles that spans the pelvic outlet, providing support to the pelvic organs and coordinating constrictor mechanisms to control urination and defecation. Symptoms reported by patients experiencing PFD include involuntary loss of stool or urine, incomplete emptying of the bowel and bladder, a sensation of fullness, bulging in the vagina, and sexual dysfunction.¹

As such, symptoms related to PFD are very common concerns raised by patients to their gastroenterologists. Data from the National Health and Nutrition Examination Survey show that 23.7% of women over the age of 20 had at least one symptom of PFD.² Unfortunately, patients experiencing pelvic floor dysfunction often are hesitant to seek care because of embarrassment or perception that limited treatment options exist for their symptoms.
 

Pelvic Floor Anatomy

Regions of the pelvis are often referred to by anatomic compartment: anterior (bladder and urethra), middle (vagina and uterus or prostate), and posterior (colon, rectum, and anal canal). Supporting these compartments is the levator ani, a muscle group that is used synonymously with the term “pelvic diaphragm.”

Khan_ Ayesha_TX_web.jpg

Continence of stool is provided by the anal sphincter muscles and the puborectalis muscle, which wraps around the posterior aspect of the anorectal canal. Damage to the musculature or sensory perception to this area may result in fecal incontinence. Defecation is a coordinated process during which the abdominal and rectal muscles contract, while the anal sphincter muscles and puborectalis simultaneously relax. A disturbance in neuromuscular coordination (dyssynergic defecation) or structural pathology such as pelvic organ prolapse may lead to obstructed defecation.

PFD is thought to be a result of one or more insults to the pelvic floor such as chronic straining, childbirth, iatrogenic injury, or systemic disease such as diabetes.³
 

Evaluation of PFD Symptoms

Patients presenting with suspected PFD necessitate a comprehensive interdisciplinary assessment. In addition to obtaining a medical, surgical, and obstetric history, details about symptoms and lifestyle should include toileting habits, diet, and physical activity. The Pelvic Floor Distress Inventory (PFDI-20) is a commonly used tool that can be employed in the clinical setting.⁴

A pelvic exam can reveal pelvic organ prolapse and other mucosal pathology. The Pelvic Organ Prolapse Quantification System (POP-Q) is a widely used classification system for describing pelvic organ prolapse.⁵ Protrusion of the rectal wall into the vagina is referred to as a rectocele, while prolapse of small bowel into the upper posterior wall of the vagina is called an enterocele. While the finding of a rectocele on exam is common in parous women and may not cause any symptoms, a larger rectocele may cause a sensation of incomplete evacuation of stool.

Menon_ Raakhi_TX_web.jpg

Initial Management

A stepwise approach to the management of PFD can allow many patients to be effectively treated without the need for surgical intervention. For patients reporting liquid stool consistency, the evaluation should pivot toward the workup and management of diarrhea, which can easily overwhelm continence mechanisms and cause fecal incontinence. Fiber supplementation to normalize stool consistency is considered first-line therapy for patients presenting with both fecal incontinence and obstructed defecation. Other tools for fecal incontinence include avoiding foods that trigger diarrhea and use of loperamide.⁶ For patients with obstructed defecation, a trial of laxatives can be followed by a prescription agent if needed, such as a secretagogue or prokinetic.⁷

Vaginal splinting is a technique that can be used in patients with rectocele, whereby a finger is inserted into the vagina and pressure is applied on the posterior vaginal wall toward the rectum. Reducing the rectocele can facilitate emptying stool from the rectum and prevent leakage of retained stool.⁸ Similarly, use of rectal irrigation enemas can also help clear retained stool.

Pelvic floor physical therapists examine the strength, coordination, and tone of the pelvic floor muscles. When hypertonic musculature is present, manual interventions may be performed including trigger point release, myofascial release, and dry needling.⁹ When hypotonic musculature or dyssynergia is present, strengthening and neuromuscular re-education are recommended. Biofeedback can be administered via surface electromyography and/or balloon training to improve rectal sensitivity. Proper defecation techniques, including positioning, breathing, and behavioral modifications, improve clinical outcomes.

Diagnostic Testing

For patients who do not improve with conservative management, further testing is recommended to characterize the underlying pathology. Typically, anorectal manometry (ARM) is performed in conjunction with the balloon expulsion test and imaging. Each modality has its strengths and limitations (see Table 1).

167838 Table_web.jpg

ARM allows for the assessment of rectal sensation and recto-anal pressures and coordination.¹⁰

Dynamic imaging, by barium defecography under fluoroscopy or MRI, captures anatomy at rest and with simulated defecation to identify pelvic organ prolapse, compartmental defects, and organ mobility.¹¹ Endoanal ultrasonography is considered in patients experiencing fecal incontinence to evaluate the integrity of the anal sphincter muscles.
 

Minimally Invasive Procedures and Surgical Options for PFD

Functional abnormalities such as dyssynergia often coexist with structural abnormalities. Because structural abnormalities are commonly found in asymptomatic patients, noninvasive functional therapy, such as pelvic floor physical therapy and anorectal biofeedback, are preferred prior to surgical repair of a structural finding. For patients with fecal incontinence, sacral nerve stimulation (SNS) has emerged as a preferred therapy due to demonstrated efficacy in symptom improvement.¹² Sphincteroplasty is reserved for those with acute sphincter injury or failure of SNS.

Corning_Brooke_TX_web.jpg

In patients with findings of intussusception, prolapse, or rectocele that have not responded to conservative therapy, referral for surgical repair may be considered. While the specific surgical approach will depend on many factors, the goal is typically excision and/or suspension of rectal tissue and reinforcement of the rectovaginal septum.

Pelvic floor disorders and related gastrointestinal complaints are very common, and likely to increase with increasing longevity and an aging population. It is critical that we are equipped with the available knowledge and tools to provide these patients with optimal care.

Introduction

The treatment of benign gallbladder disease has changed substantially in the past decade, but this represents only a snapshot in the evolutionary history of the management of this organ. What began as a problem managed exclusively by open cholecystectomy (CCY) transitioned into a race toward minimally invasive approaches in the 1980s, with advances from gastroenterology, surgery, and radiology.

The opening strides were made in 1980 with the first description of percutaneous cholecystostomy (PC) by Dr. R.W. Radder.¹ Shortly thereafter, in 1984, Dr. Richard Kozarek first reported the feasibility of selective cystic duct cannulation during endoscopic retrograde cholangiopancreatography (ERCP).² Subsequent stenting for the treatment of acute cholecystitis (endoscopic transpapillary gallbladder drainage, ET-GBD) was then reported by Tamada et. al. in 1991.³ Not to be outdone, the first laparoscopic cholecystectomy (LC) was completed by Dr. Med Erich Mühe of Germany in 1985.⁴ More recently, with the expansion of interventional endoscopic ultrasound (EUS), the first transmural EUS-guided gallbladder drainage (EUS-GBD) was described by Dr. Baron and Dr. Topazian in 2007.⁵

Techniques & Tips

ET-GBD

• During ERCP, after successful cannulation of the bile duct, attempted wire cannulation of the cystic duct is performed.

A cholangiogram, which clearly delineates the insertion of the cystic duct into the main bile duct, can enhance cannulation success. Rotatable fluoroscopy can facilitate identification.

• After anatomy is clear, wire access is often best achieved using a sphincterotome or stone retrieval (occlusion) balloon.

The balloon, once inflated, can be pulled downward to establish traction on the main bile duct, which can straighten the approach.

• After superficial wire engagement into the cystic duct, the accessory used can be slowly advanced into the cystic duct to stabilize the catheter and then navigate the valves of Heister to reach the gallbladder lumen.

Use of a sphincterotome, which directs toward the patient’s right (most often direction of cystic duct takeoff), is helpful. Angled guidewires are preferable. We often use a 0.035-inch, 260-cm angled hydrophilic wire (GLIDEWIRE; Terumo, Somerset, NJ) to overcome this challenging portion of ET-GBD.

If despite the above maneuvers the guidewire has failed to enter the cystic duct, cholangioscopy can be used to identify the orifice and/or stabilize deep wire cannulation. This is often cumbersome, time consuming, does not always produce success, and requires additional expertise.

• If a stone is encountered that cannot be extracted or traversed by a guidewire, cholangioscopy with electrohydraulic lithotripsy can be pursued.
• After the guidewire has entered the gallbladder, a 5 French or 7 French plastic double pigtail stent is placed. Typical lengths are 9-15 cm.

Some authors prefer to use two side-by-side plastic stents.¹² This has been shown retrospectively to enhance the long term clinical success of ET-GBD but with additional technical difficulty.

• This stent can remain in place indefinitely and need not be exchanged, though it should be removed just prior to CCY if pursued. Alternatively, the surgeon can be alerted to its presence and, if comfortable, it can be removed intraoperatively.

EUS-GBD

• Use of fluoroscopy is optional but can enhance technical success in selected situations.
• Conversion, or internalization, of PC is reasonable and can enhance patient quality of life.¹³
• If the gallbladder wall is not in close apposition to the duodenal (or gastric) wall, consider measuring the distance.

We preferentially use 10-mm diameter by 10-mm saddle length LAMS for EUS-GBD, unless the above distance warrants use of a 15-mm by 15-mm LAMS (AXIOS, Boston Scientific, Marlborough, MA). If the distance is greater than 15 mm, consider searching for an alternative site, using a traditional biliary fully covered self-expandable metal stent (FCSEMS) for longer length, or converting to ET-GBD. Smaller diameter (8 mm) with an 8-mm saddle length can be used as well. The optimal diameter is unknown and also dependent on whether transluminal endoscopic diagnosis or therapy is a consideration.

• If there is difficulty locating the gallbladder, it may be decompressed or small (particularly if PC or a partial CCY has already been performed).

If a cholecystostomy tube is in place, instillation of sterile water via the tube can sometimes improve the target for LAMS placement, though caution should be made to not over-distend the gallbladder. ERCP with placement of a nasobiliary tube into the gallbladder can also serve this purpose and has been previously described.¹⁴

The gallbladder can be punctured with a 19-gauge FNA needle to instill sterile water and distend the gallbladder with the added benefit of being able to pass a guidewire, which may enhance procedural safety in difficult cases. However, success of this technique is contingent on fluid remaining within the gallbladder and not transiting out via the cystic duct. Expedient exchange of the FNA needle for the LAMS device may be necessary.

• Attempt to confirm location within the duodenum prior to puncture, as gastric origins can pose unique ramifications (i.e. potential for partial gastric outlet obstruction, obstruction of LAMS with food debris, etc.).

It can be easy to mistake an unintentional pre-pyloric position for a position within the duodenum since the working channel is behind (proximal to) the echoprobe.

• Turning off Doppler flow prior to advancement of the cautery enhanced LAMS can reduce obscurement of views on entry into the gallbladder. Lack of certainty about entry or misdeployment after presumed entry herald the most challenging aspect of EUS-GBD.

Utilization of a previously placed guidewire or advancement of one preloaded into the LAMS can aid in both enhancing confidence in location and assist with salvage maneuvers, if needed.

• After successful deployment of the LAMS we routinely place a double pigtail plastic stent through it (typically 7 French by 4 cm) to maintain patency. This may also prevent bleeding from the LAMS flange abrading the wall of either lumen.
• We routinely exchange the LAMS for two double pigtail plastic stents (typically 7 French by 4 cm) 4 weeks after initial placement especially when there is a more than modest residual stone burden (data in press). These plastic stents can remain in place indefinitely.

This exchange can be deferred if the patient is not expected to survive until the one-year anniversary of LAMS deployment. After one year the LAMS plastic covering may degrade and pose additional problems.¹⁵

LAMS Misdeployment Salvage Tips

• Salvage techniques can vary from simple to complex.
• If a wire is in place, it can be used to balloon or catheter dilate the tract and place a FCSEMS traversing the gallbladder and duodenal/gastric lumens. A similar approach can be used if the LAMS deployed on only one side (gallbladder or duodenum/stomach) and the other flange is within the peritoneum.
• The most challenging scenario to salvage is if the LAMS is misdeployed or becomes dislodged and no wire is present. This is why the use of a guidewire, even if preloaded into the LAMS and placement is freehand, is essential for EUS-GBD. A potential technique is to balloon dilate the duodenal/gastric defect and drive the endoscope into the peritoneum to reconnect that lumen to the gallbladder defect or LAMS, depending on the site of misdeployment. Doing so requires a high degree of commitment and skill and should not be done casually.
• If uncertainty remains or if misdeployment has occurred and salvage attempts have failed, consider closure of the duodenal/gastric defect and conversion to ET-GBD.

This may both treat the initial procedural indication and assist with what is essentially a large bile leak, which might also require percutaneous therapy for non-surgical management.

• For endoscopists with limited experience at salvage techniques, it is reasonable for the threshold for conversion to be low, assuming experience with and confidence in ET-GBD is high.
• If salvage is successful but ambiguity remains, consider obtaining a cholangiogram via the LAMS to confirm positioning and absence of leak.

Adverse Events

Both ET-GBD and EUS-GBD should be performed by an endoscopist comfortable with their techniques and the management of their adverse events (AEs). Rates for EUS-GBD AEs in patients at high risk for LC were reported in one international multicenter registry to be 15.3% with a 30-day mortality of 9.2%, with a significant predictor of AE being endoscopist experience less than 25 procedures.¹⁶ A meta-analysis also found an overall AE rate of 18.31%, with rates for perforation and stent related AEs (i.e. migration, occlusion, pneumoperitoneum) being 6.71% and 8.16%, respectively.¹⁷ For this reason, we recommend that patients with cholecystitis who are deemed to be poor surgical candidates be transferred to a tertiary referral center with expertise in these approaches. Rates of AEs for ET-GBD are similar to that for standard ERCP, with reported ranges of 5%-10.3%.¹⁰
 

Comparisons Between Techniques

The decision on which technique to utilize for endoscopic management of cholecystitis or symptomatic cholelithiasis depends first and foremost on the expertise and comfort level of the endoscopist. Given the additional training that an advanced endoscopist needs to perform EUS-GBD, combined with the perhaps slightly higher AE rate and permanency of endoscopic cholecystostomy, it is reasonable to proceed with a trial of ET-GBD if confidence is insufficient. However, ET-GBD can certainly be more technically challenging and less effective than EUS-GBD, with lower reported technical and clinical success rates (technical 85.3% vs 93.0%, clinical 95.2% vs 97.3%).¹⁸ Despite this, the rate of recurrence of cholecystitis is similar between ET-GBD and EUS-GBD (4.6% vs 4.2%).¹⁹ As stated above in the Techniques & Tips section, some authors utilize two plastic stents for ET-GBD for this purpose, though with increased technical difficulty. It is important to remember that these numbers, when paired with AE rates, represent the achievements of expert endoscopists.

Discussion with your surgery team is important when deciding modality. If the patient is felt to be a potential candidate for CCY, and EUS-GBD is not being used as a destination therapy, the surgeon may prefer ET-GBD. EUS-GBD may enhance the difficulty of CCY, though at least one study demonstrated that this was no different than PC with similar rates of conversion from LC to open CCY.²⁰ This conversation is most critical for patients who are potential liver transplant candidates. For patients where this is not a consideration there is some evidence to suggest equivalency between LC and EUS-GBD, though certainly EUS-GBD has not yet supplanted LC as the treatment of choice.²¹

While there may eventually be a shift towards EUS-GBD instead of LC in certain patient groups, what is clearer are the advantages of EUS-GBD over PC. One recent meta-analysis revealed that EUS-GBD has significantly favorable odds of overall adverse events (OR 0.43, 95% CI 0.18-1.00), shorter hospital stay (2.76 less days, 95% CI 0.31-5.20 less days), reinterventions (OR 0.15, 95% CI 0.02-0.98), and unplanned readmissions (OR 0.14, 95% CI 0.03-0.70) compared to PC.²² Beyond the data, though, are the emotional and psychological impacts an external drain can have on a patient.
 

Conclusion

When expertise is available, endoscopic treatment of benign gallbladder disease has a definite role but should be undertaken only by those with the experience and skill to safely do so. Decision to proceed, especially with EUS-GBD, should be accompanied by conversation and collaboration with surgical teams. If a patient is under consideration for PC instead of LC, it may be worthwhile to seek consultation with a local center with expertise in EUS-GBD or ET-GBD. The adoption of these techniques is part of the paradigm shift, seen broadly throughout medicine, towards minimally invasive interventions, particularly in advanced endoscopy.

Introduction

The treatment of benign gallbladder disease has changed substantially in the past decade, but this represents only a snapshot in the evolutionary history of the management of this organ. What began as a problem managed exclusively by open cholecystectomy (CCY) transitioned into a race toward minimally invasive approaches in the 1980s, with advances from gastroenterology, surgery, and radiology.

The opening strides were made in 1980 with the first description of percutaneous cholecystostomy (PC) by Dr. R.W. Radder.¹ Shortly thereafter, in 1984, Dr. Richard Kozarek first reported the feasibility of selective cystic duct cannulation during endoscopic retrograde cholangiopancreatography (ERCP).² Subsequent stenting for the treatment of acute cholecystitis (endoscopic transpapillary gallbladder drainage, ET-GBD) was then reported by Tamada et. al. in 1991.³ Not to be outdone, the first laparoscopic cholecystectomy (LC) was completed by Dr. Med Erich Mühe of Germany in 1985.⁴ More recently, with the expansion of interventional endoscopic ultrasound (EUS), the first transmural EUS-guided gallbladder drainage (EUS-GBD) was described by Dr. Baron and Dr. Topazian in 2007.⁵

Techniques & Tips

ET-GBD

• During ERCP, after successful cannulation of the bile duct, attempted wire cannulation of the cystic duct is performed.

A cholangiogram, which clearly delineates the insertion of the cystic duct into the main bile duct, can enhance cannulation success. Rotatable fluoroscopy can facilitate identification.

• After anatomy is clear, wire access is often best achieved using a sphincterotome or stone retrieval (occlusion) balloon.

The balloon, once inflated, can be pulled downward to establish traction on the main bile duct, which can straighten the approach.

• After superficial wire engagement into the cystic duct, the accessory used can be slowly advanced into the cystic duct to stabilize the catheter and then navigate the valves of Heister to reach the gallbladder lumen.

Use of a sphincterotome, which directs toward the patient’s right (most often direction of cystic duct takeoff), is helpful. Angled guidewires are preferable. We often use a 0.035-inch, 260-cm angled hydrophilic wire (GLIDEWIRE; Terumo, Somerset, NJ) to overcome this challenging portion of ET-GBD.

If despite the above maneuvers the guidewire has failed to enter the cystic duct, cholangioscopy can be used to identify the orifice and/or stabilize deep wire cannulation. This is often cumbersome, time consuming, does not always produce success, and requires additional expertise.

• If a stone is encountered that cannot be extracted or traversed by a guidewire, cholangioscopy with electrohydraulic lithotripsy can be pursued.
• After the guidewire has entered the gallbladder, a 5 French or 7 French plastic double pigtail stent is placed. Typical lengths are 9-15 cm.

Some authors prefer to use two side-by-side plastic stents.¹² This has been shown retrospectively to enhance the long term clinical success of ET-GBD but with additional technical difficulty.

• This stent can remain in place indefinitely and need not be exchanged, though it should be removed just prior to CCY if pursued. Alternatively, the surgeon can be alerted to its presence and, if comfortable, it can be removed intraoperatively.

EUS-GBD

• Use of fluoroscopy is optional but can enhance technical success in selected situations.
• Conversion, or internalization, of PC is reasonable and can enhance patient quality of life.¹³
• If the gallbladder wall is not in close apposition to the duodenal (or gastric) wall, consider measuring the distance.

We preferentially use 10-mm diameter by 10-mm saddle length LAMS for EUS-GBD, unless the above distance warrants use of a 15-mm by 15-mm LAMS (AXIOS, Boston Scientific, Marlborough, MA). If the distance is greater than 15 mm, consider searching for an alternative site, using a traditional biliary fully covered self-expandable metal stent (FCSEMS) for longer length, or converting to ET-GBD. Smaller diameter (8 mm) with an 8-mm saddle length can be used as well. The optimal diameter is unknown and also dependent on whether transluminal endoscopic diagnosis or therapy is a consideration.

• If there is difficulty locating the gallbladder, it may be decompressed or small (particularly if PC or a partial CCY has already been performed).

If a cholecystostomy tube is in place, instillation of sterile water via the tube can sometimes improve the target for LAMS placement, though caution should be made to not over-distend the gallbladder. ERCP with placement of a nasobiliary tube into the gallbladder can also serve this purpose and has been previously described.¹⁴

The gallbladder can be punctured with a 19-gauge FNA needle to instill sterile water and distend the gallbladder with the added benefit of being able to pass a guidewire, which may enhance procedural safety in difficult cases. However, success of this technique is contingent on fluid remaining within the gallbladder and not transiting out via the cystic duct. Expedient exchange of the FNA needle for the LAMS device may be necessary.

• Attempt to confirm location within the duodenum prior to puncture, as gastric origins can pose unique ramifications (i.e. potential for partial gastric outlet obstruction, obstruction of LAMS with food debris, etc.).

It can be easy to mistake an unintentional pre-pyloric position for a position within the duodenum since the working channel is behind (proximal to) the echoprobe.

• Turning off Doppler flow prior to advancement of the cautery enhanced LAMS can reduce obscurement of views on entry into the gallbladder. Lack of certainty about entry or misdeployment after presumed entry herald the most challenging aspect of EUS-GBD.

Utilization of a previously placed guidewire or advancement of one preloaded into the LAMS can aid in both enhancing confidence in location and assist with salvage maneuvers, if needed.

• After successful deployment of the LAMS we routinely place a double pigtail plastic stent through it (typically 7 French by 4 cm) to maintain patency. This may also prevent bleeding from the LAMS flange abrading the wall of either lumen.
• We routinely exchange the LAMS for two double pigtail plastic stents (typically 7 French by 4 cm) 4 weeks after initial placement especially when there is a more than modest residual stone burden (data in press). These plastic stents can remain in place indefinitely.

This exchange can be deferred if the patient is not expected to survive until the one-year anniversary of LAMS deployment. After one year the LAMS plastic covering may degrade and pose additional problems.¹⁵

LAMS Misdeployment Salvage Tips

• Salvage techniques can vary from simple to complex.
• If a wire is in place, it can be used to balloon or catheter dilate the tract and place a FCSEMS traversing the gallbladder and duodenal/gastric lumens. A similar approach can be used if the LAMS deployed on only one side (gallbladder or duodenum/stomach) and the other flange is within the peritoneum.
• The most challenging scenario to salvage is if the LAMS is misdeployed or becomes dislodged and no wire is present. This is why the use of a guidewire, even if preloaded into the LAMS and placement is freehand, is essential for EUS-GBD. A potential technique is to balloon dilate the duodenal/gastric defect and drive the endoscope into the peritoneum to reconnect that lumen to the gallbladder defect or LAMS, depending on the site of misdeployment. Doing so requires a high degree of commitment and skill and should not be done casually.
• If uncertainty remains or if misdeployment has occurred and salvage attempts have failed, consider closure of the duodenal/gastric defect and conversion to ET-GBD.

This may both treat the initial procedural indication and assist with what is essentially a large bile leak, which might also require percutaneous therapy for non-surgical management.

• For endoscopists with limited experience at salvage techniques, it is reasonable for the threshold for conversion to be low, assuming experience with and confidence in ET-GBD is high.
• If salvage is successful but ambiguity remains, consider obtaining a cholangiogram via the LAMS to confirm positioning and absence of leak.

Adverse Events

Both ET-GBD and EUS-GBD should be performed by an endoscopist comfortable with their techniques and the management of their adverse events (AEs). Rates for EUS-GBD AEs in patients at high risk for LC were reported in one international multicenter registry to be 15.3% with a 30-day mortality of 9.2%, with a significant predictor of AE being endoscopist experience less than 25 procedures.¹⁶ A meta-analysis also found an overall AE rate of 18.31%, with rates for perforation and stent related AEs (i.e. migration, occlusion, pneumoperitoneum) being 6.71% and 8.16%, respectively.¹⁷ For this reason, we recommend that patients with cholecystitis who are deemed to be poor surgical candidates be transferred to a tertiary referral center with expertise in these approaches. Rates of AEs for ET-GBD are similar to that for standard ERCP, with reported ranges of 5%-10.3%.¹⁰
 

Comparisons Between Techniques

The decision on which technique to utilize for endoscopic management of cholecystitis or symptomatic cholelithiasis depends first and foremost on the expertise and comfort level of the endoscopist. Given the additional training that an advanced endoscopist needs to perform EUS-GBD, combined with the perhaps slightly higher AE rate and permanency of endoscopic cholecystostomy, it is reasonable to proceed with a trial of ET-GBD if confidence is insufficient. However, ET-GBD can certainly be more technically challenging and less effective than EUS-GBD, with lower reported technical and clinical success rates (technical 85.3% vs 93.0%, clinical 95.2% vs 97.3%).¹⁸ Despite this, the rate of recurrence of cholecystitis is similar between ET-GBD and EUS-GBD (4.6% vs 4.2%).¹⁹ As stated above in the Techniques & Tips section, some authors utilize two plastic stents for ET-GBD for this purpose, though with increased technical difficulty. It is important to remember that these numbers, when paired with AE rates, represent the achievements of expert endoscopists.

Discussion with your surgery team is important when deciding modality. If the patient is felt to be a potential candidate for CCY, and EUS-GBD is not being used as a destination therapy, the surgeon may prefer ET-GBD. EUS-GBD may enhance the difficulty of CCY, though at least one study demonstrated that this was no different than PC with similar rates of conversion from LC to open CCY.²⁰ This conversation is most critical for patients who are potential liver transplant candidates. For patients where this is not a consideration there is some evidence to suggest equivalency between LC and EUS-GBD, though certainly EUS-GBD has not yet supplanted LC as the treatment of choice.²¹

While there may eventually be a shift towards EUS-GBD instead of LC in certain patient groups, what is clearer are the advantages of EUS-GBD over PC. One recent meta-analysis revealed that EUS-GBD has significantly favorable odds of overall adverse events (OR 0.43, 95% CI 0.18-1.00), shorter hospital stay (2.76 less days, 95% CI 0.31-5.20 less days), reinterventions (OR 0.15, 95% CI 0.02-0.98), and unplanned readmissions (OR 0.14, 95% CI 0.03-0.70) compared to PC.²² Beyond the data, though, are the emotional and psychological impacts an external drain can have on a patient.
 

Conclusion

When expertise is available, endoscopic treatment of benign gallbladder disease has a definite role but should be undertaken only by those with the experience and skill to safely do so. Decision to proceed, especially with EUS-GBD, should be accompanied by conversation and collaboration with surgical teams. If a patient is under consideration for PC instead of LC, it may be worthwhile to seek consultation with a local center with expertise in EUS-GBD or ET-GBD. The adoption of these techniques is part of the paradigm shift, seen broadly throughout medicine, towards minimally invasive interventions, particularly in advanced endoscopy.

• If uncertainty remains or if misdeployment has occurred and salvage attempts have failed, consider closure of the duodenal/gastric defect and conversion to ET-GBD.

This may both treat the initial procedural indication and assist with what is essentially a large bile leak, which might also require percutaneous therapy for non-surgical management.

• For endoscopists with limited experience at salvage techniques, it is reasonable for the threshold for conversion to be low, assuming experience with and confidence in ET-GBD is high.
• If salvage is successful but ambiguity remains, consider obtaining a cholangiogram via the LAMS to confirm positioning and absence of leak.

Adverse Events

Both ET-GBD and EUS-GBD should be performed by an endoscopist comfortable with their techniques and the management of their adverse events (AEs). Rates for EUS-GBD AEs in patients at high risk for LC were reported in one international multicenter registry to be 15.3% with a 30-day mortality of 9.2%, with a significant predictor of AE being endoscopist experience less than 25 procedures.¹⁶ A meta-analysis also found an overall AE rate of 18.31%, with rates for perforation and stent related AEs (i.e. migration, occlusion, pneumoperitoneum) being 6.71% and 8.16%, respectively.¹⁷ For this reason, we recommend that patients with cholecystitis who are deemed to be poor surgical candidates be transferred to a tertiary referral center with expertise in these approaches. Rates of AEs for ET-GBD are similar to that for standard ERCP, with reported ranges of 5%-10.3%.¹⁰
 

Comparisons Between Techniques

The decision on which technique to utilize for endoscopic management of cholecystitis or symptomatic cholelithiasis depends first and foremost on the expertise and comfort level of the endoscopist. Given the additional training that an advanced endoscopist needs to perform EUS-GBD, combined with the perhaps slightly higher AE rate and permanency of endoscopic cholecystostomy, it is reasonable to proceed with a trial of ET-GBD if confidence is insufficient. However, ET-GBD can certainly be more technically challenging and less effective than EUS-GBD, with lower reported technical and clinical success rates (technical 85.3% vs 93.0%, clinical 95.2% vs 97.3%).¹⁸ Despite this, the rate of recurrence of cholecystitis is similar between ET-GBD and EUS-GBD (4.6% vs 4.2%).¹⁹ As stated above in the Techniques & Tips section, some authors utilize two plastic stents for ET-GBD for this purpose, though with increased technical difficulty. It is important to remember that these numbers, when paired with AE rates, represent the achievements of expert endoscopists.

Discussion with your surgery team is important when deciding modality. If the patient is felt to be a potential candidate for CCY, and EUS-GBD is not being used as a destination therapy, the surgeon may prefer ET-GBD. EUS-GBD may enhance the difficulty of CCY, though at least one study demonstrated that this was no different than PC with similar rates of conversion from LC to open CCY.²⁰ This conversation is most critical for patients who are potential liver transplant candidates. For patients where this is not a consideration there is some evidence to suggest equivalency between LC and EUS-GBD, though certainly EUS-GBD has not yet supplanted LC as the treatment of choice.²¹

While there may eventually be a shift towards EUS-GBD instead of LC in certain patient groups, what is clearer are the advantages of EUS-GBD over PC. One recent meta-analysis revealed that EUS-GBD has significantly favorable odds of overall adverse events (OR 0.43, 95% CI 0.18-1.00), shorter hospital stay (2.76 less days, 95% CI 0.31-5.20 less days), reinterventions (OR 0.15, 95% CI 0.02-0.98), and unplanned readmissions (OR 0.14, 95% CI 0.03-0.70) compared to PC.²² Beyond the data, though, are the emotional and psychological impacts an external drain can have on a patient.
 

Conclusion

When expertise is available, endoscopic treatment of benign gallbladder disease has a definite role but should be undertaken only by those with the experience and skill to safely do so. Decision to proceed, especially with EUS-GBD, should be accompanied by conversation and collaboration with surgical teams. If a patient is under consideration for PC instead of LC, it may be worthwhile to seek consultation with a local center with expertise in EUS-GBD or ET-GBD. The adoption of these techniques is part of the paradigm shift, seen broadly throughout medicine, towards minimally invasive interventions, particularly in advanced endoscopy.
