Perioperative Medicine

BACKGROUND: Patient preferences regarding cardiopulmonary resuscitation (CPR) are important, especially during hospitalization when a patient’s health is changing, yet many patients are not adequately informed or involved in the decision-making process.

OBJECTIVES: We examined the effect of an informational video about CPR on hospitalized patients’ code status choices.

DESIGN: This was a prospective, randomized trial conducted at the Veteran’s Affairs Hospital in Minneapolis.

PARTICIPANTS: We enrolled 119 patients who were hospitalized on the general medicine service and at least 65 years old. The majority were men (97%) with a mean age of 75.

INTERVENTION: A video described code status choices: full code (CPR and intubation if required), do not resuscitate (DNR), and do not resuscitate/do not intubate (DNR/DNI). Participants were randomized to watch the video (n = 59) or usual care (n = 60).

MEASUREMENTS: The primary outcome was participants’ code status preferences. Secondary outcomes included a questionnaire designed to evaluate participants’ trust in their health care team and their knowledge and perceptions about CPR.

RESULTS: Participants who viewed the video were less likely to choose full code (37%), compared with participants in the usual-care group (71%), and were more likely to choose DNR/DNI (56% in the video group vs. 17% in the control group) (P < .00001). We did not see a difference in trust in their health care team or knowledge and perceptions about CPR as assessed by our questionnaire.

CONCLUSIONS: Hospitalized patients who watched a video about CPR and code status choices were less likely to choose full code and more likely to choose DNR/DNI.

Summary

The growth in opiate prescribing and associated increases in adverse events has created unique challenges for hospitalists, including how best to assess pain and opiate use disorders and how to safely prescribe opiates during hospitalization and at discharge.

These challenges are compounded by patient and system factors and a paucity of evidence-based guidelines to help guide safe administration of opiates in hospitalized patients. This can mean frustration for hospitalists and harm for patients.

Key takeaways for HM

• When assessing patients’ pain, it is crucial to differentiate between acute and chronic pain (or both) and whether it is nociceptive or neuropathic. Misclassification of pain contributes to inappropriate exposure and escalation of opiate therapy during hospitalization.
• Always consider nonopioid analgesics such as NSAIDs first and pair them with opiates. Studies in a variety of conditions have demonstrated that these are equally, if not more, effective, even for severe pain, such as with renal colic. Reserve opiates for moderate to severe pain.
• Always assess whether the benefits of initiating or continuing opioid therapy outweigh the risks for individual patients. There is no validated tool to predict risk for adverse events and/or opioid abuse disorder but a careful review of patient history can identify established risk factors (such as a history of mental illness or substance abuse disorders, renal impairment, or other comorbidities). In addition, nearly all states now have Prescription Drug Monitoring Programs, and hospitalists should consult these routinely when prescribing opiates.
• Always clearly discuss expectations and risks of opioid therapy, including the potential for development of opioid use disorders with hospitalized patients prior to initiation. Emphasize pain reduction rather than elimination and focus on functional goals such as improved mobility. Also, set expectations for stepping down treatment up front.
• Use the lowest effective dose of immediate-release opioids (preferably oral route) for shortest duration possible. Long acting opiates are associated with increased risk of adverse events, and their initiation should generally be avoided in hospitalized patients with noncancer pain.
• Minimize risk by avoiding concurrent administration of other medications with sedative properties, especially benzodiazepines, which have been found to significantly increase the risk of adverse events, including overdose.
• Recognize that chronic opioid use often begins with treatment of acute pain during hospitalization. Adopt best practice for discharge, including prescribing shorter courses whenever possible, discussing initiation, and changes or modifications in opiate therapy with patients’ primary care provider, and ensure timely postdischarge follow-up. Also consider coprescription of naloxone at discharge for higher risk patients.

Clinical question: What is the clinical impact of implementing a policy to no longer process urine specimens for perioperative screening in patients undergoing elective joint arthroplasty (EJA)?

Background: Despite prior studies indicating the lack of clinical benefit, preoperative urine cultures are still frequently obtained in patients undergoing EJA in attempts to reduce the risk of periprosthetic joint infections (PJI).

Study Design: Time series analysis.

Setting: Holland Orthopedic and Arthritic Center (HOAC) of Sunnybrook Health Sciences Centre.

Synopsis: After a multidisciplinary meeting, obtaining routine urine culture screening was removed from the preoperative order set. A time series analysis was performed to review the frequency of screening urine cultures obtained and processed, the number of patients treated for asymptomatic bacteriuria (ASB), and the incidence of PJI before and after the new policy was implemented. After the policy change, only 129 screening urine cultures were obtained prior to 1,891 EJAs (7 per 100 EJA; 95% CI 6-8; P less than .0001) which is a drastic decrease from the 3,069 screening urine cultures obtained prior to 3,523 EJAs (87 per 100 EJA; 95% CI, 86-88) before the policy change. Prior to the policy change, of the 352 positive urine cultures, 43 received perioperative treatment for ASB, and PJI incidence was 1/3523 (0.03%; 95% CI, 0.001-02). After the policy change, no perioperative antibiotics were prescribed for ASB, and PJI rate did not significantly change at 3/1891 (0.2%; 95% CI, 0.05-0.5; P = .1).

The study was limited by its low power to detect for small differences in rates because of its small PJI rate occurrence.

Bottom Line: A multidisciplinary approach in eliminating routine urine screening prior to EJA resulted in a decrease of urine cultures obtained and a decrease in treatment for asymptomatic bacteriuria, with no significant change in PJI rate. This change in clinical practice is supported by current evidence and has a significant impact on cost savings.

Clinical question: Is withholding angiotensin-converting enzyme inhibitors (ACEI) or angiotensin II receptor blockers (ARBs) prior to noncardiac surgery associated with a lower risk of a 30-day composite outcome of all-cause death, myocardial injury after noncardiac surgery, and stroke when compared with continuing them on the day of surgery?

Background: The current American College of Cardiology/American Heart Association guidelines recommend continuing ACEI and ARBs for noncardiac surgery. However, many clinicians, including anesthesiologists, withhold these medications to prevent intraoperative hypotension. Because of the lack of strong evidence regarding clinical outcomes, the decision to withhold ACEI and ARBs prior to noncardiac surgery is currently dictated by physician preference and local policy.

Study Design: Prospective cohort study.

Setting: Analysis sample from the VISION study (Vascular Events in Noncardiac Surgery Patients Cohort Evaluation), which included 12 centers in eight countries.

Synopsis: A sample analysis was performed on 14,687 patients from the VISION study, who were at least 45 years old and undergoing noncardiac surgery and who required an overnight hospital admission. A total of 4,802 patients were taking ACEI/ARBs at baseline, and, for 1,245 (25.9%) of those patients, ACEI/ARBs were withheld at least 24 hours before surgery. Using multivariable regression models, the authors found that patients for whom ACEI/ARBs were withheld were less likely to suffer from the primary composite outcome of 30-day all-cause death, myocardial injury after noncardiac surgery, and stroke (12% vs 12.9%; adjusted relative risk, 0.82; 95% confidence interval, 0.7-0.96; P = .01). Withholding ACEI/ARBs prior to surgery was also associated with less risk of clinically important intraoperative hypotension, while the risk of postoperative hypotension was similar between the two groups.

Given that this was an observational study, analysis is limited because of the inability to account for every potential confounding factor.

Bottom Line: The study suggests a lower risk of postoperative death, stroke, and myocardial injury in patients for whom ACEI/ARBs were withheld prior to noncardiac surgery. A large randomized trial is needed to confirm the findings suggested by this analysis.

Administration of infliximab within 4 weeks of elective knee or hip arthroplasty did not have any significant effect on patients’ risk of serious infection after surgery, whereas the use of glucocorticoids increased that risk, in an analysis of a Medicare claims database.

“This increased risk with glucocorticoids has been suggested by previous studies [and] although this risk may be related in part to increased disease severity among glucocorticoid treated patients, a direct medication effect is likely. [These data suggest] that prolonged interruptions in infliximab therapy prior to surgery may be counterproductive if higher dose glucocorticoid therapy is used in substitution,” wrote the authors of the new study, led by Michael D. George, MD, of the University of Pennsylvania in Philadelphia.

Dr. George and his colleagues examined data from the U.S. Medicare claims system on 4,288 elective knee or hip arthroplasties in individuals with rheumatoid arthritis, inflammatory bowel disease, psoriasis, psoriatic arthritis, or ankylosing spondylitis who received infliximab within 6 months prior to the operation during 2007-2013 (Arthritis Care Res. 2017 Jan 27. doi: 10.1002/acr.23209).

The patients had to have received infliximab at least three times within a year of their procedure to establish that they were receiving stable therapy over a long-term period. The investigators also looked at oral prednisone, prednisolone, and methylprednisolone prescriptions and used data on average dosing to determine how much was administered to each subject.

“Although previous studies have treated TNF stopping vs. not stopping as a dichotomous exposure based on an arbitrary (and variable) stopping definition, in this study the primary analysis evaluated stop timing as a more general categorical exposure using 4-week intervals (half the standard rheumatoid arthritis dosing interval) to allow better assessment of the optimal stop timing,” the authors explained.

Stopping infliximab within 4 weeks of the operation did not significantly influence the rate of serious infection within 30 days (adjusted odds ratio, 0.90; 95% CI, 0.60-1.34) and neither did stopping within 4-8 weeks (OR, 0.95; 95% CI, 0.62-1.36) when compared against stopping 8-12 weeks before surgery. Of the 4,288 arthroplasties, 270 serious infections (6.3%) occurred within 30 days of the operation.

There also was no significant difference between stopping within 4 weeks and 8-12 weeks in the rate of prosthetic joint infection within 1 year of the operation (hazard ratio, 0.98; 95% CI, 0.52-1.87). Overall, prosthetic joint infection occurred 2.9 times per 100 person-years.

However, glucocorticoid doses of more than 10 mg per day were risky. The odds for a serious infection within 30 days after surgery more than doubled with that level of use (OR, 2.11; 95% CI, 1.30-3.40), while the risk for a prosthetic joint infection within 1 year of the surgery also rose significantly (HR, 2.70; 95% CI, 1.30-5.60).

Administration of infliximab within 4 weeks of elective knee or hip arthroplasty did not have any significant effect on patients’ risk of serious infection after surgery, whereas the use of glucocorticoids increased that risk, in an analysis of a Medicare claims database.

“This increased risk with glucocorticoids has been suggested by previous studies [and] although this risk may be related in part to increased disease severity among glucocorticoid treated patients, a direct medication effect is likely. [These data suggest] that prolonged interruptions in infliximab therapy prior to surgery may be counterproductive if higher dose glucocorticoid therapy is used in substitution,” wrote the authors of the new study, led by Michael D. George, MD, of the University of Pennsylvania in Philadelphia.

Dr. George and his colleagues examined data from the U.S. Medicare claims system on 4,288 elective knee or hip arthroplasties in individuals with rheumatoid arthritis, inflammatory bowel disease, psoriasis, psoriatic arthritis, or ankylosing spondylitis who received infliximab within 6 months prior to the operation during 2007-2013 (Arthritis Care Res. 2017 Jan 27. doi: 10.1002/acr.23209).

The patients had to have received infliximab at least three times within a year of their procedure to establish that they were receiving stable therapy over a long-term period. The investigators also looked at oral prednisone, prednisolone, and methylprednisolone prescriptions and used data on average dosing to determine how much was administered to each subject.

Clinical question: How do pentasaccharides compare to other anticoagulants in postoperative venous thromboembolism prevention?

Background: Venous thromboembolism (VTE) remains a leading cause of preventable hospital related death. Pentasaccharides selectively inhibit factor Xa to inhibit clotting and exhibit a lower risk of heparin induced thrombocytopenia (HIT) compared to low molecular weight heparin (LMWH) and unfractionated heparin. We lack a formal recommendation regarding the pentasaccharides superiority or inferiority, relative to other anticoagulants, in the perioperative setting.

Study design: Cochrane review.

Setting: Hospital and outpatient.

Synopsis: Authors searched randomized controlled trials involving pentasaccharides versus other VTE prophylaxis to obtain 25 studies totaling 21,004 subjects undergoing orthopedic, abdominal, cardiac bypass, thoracic, and bariatric surgery; hospitalized patients, immobilized patients, and those with superficial venous thrombosis. Selected studies pertained to fondaparinux and VTE prevention. Fondaparinux was superior to placebo in prevention of DVT and VTE. Compared to LMWH, fondaparinux reduced total VTE (RR, 0.55, 95% CI, 0.42-0.73) and DVT (RR, 0.54, 95% CI, 0.40-0.71), but carried a higher rate of major bleeding compared to placebo (RR, 2.56, 95% CI, 1.48-4.44) and LMWH (RR, 1.38, 95% CI, 1.09-1.75). The all cause death and major adverse events for fondaparinux versus placebo and LMWH were not statistically significant. Limitations of this review include the predominance of orthopedic patients, variable duration of treatment, and low-moderate quality data.

Bottom line: Fondaparinux demonstrates better perioperative total VTE and DVT reduction compared to LMWH, but it increases the incidence of major bleeding.

Clinical question: Is DVT prophylaxis necessary with lower leg casting or after knee arthroscopy?

Background: Patients who undergo immobilization from casting or knee arthroscopic surgery are thought to be at increased risk for venous thromboembolism (VTE).

NEW ORLEANS – Despite increasing use of transcatheter aortic valve replacement for patients with severe aortic stenosis at intermediate risk for surgery, the procedure is meeting selected resistance because of ongoing concerns about the procedure’s limitations.

As more data emerge from randomized trials and registries, cardiologists and cardiothoracic surgeons see the choice between transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) for patients at intermediate surgical risk as something to individualize based on factors that include age, the type of TAVR access possible (transfemoral or an alternative route), and of course, patient preference. An added variable is the constant stream of new data that keeps TAVR in flux, with improved and smaller valves and delivery systems coming onto the market that eclipse the experience and lessons learned from older TAVR systems.

In intermediate-risk patients, usually defined as those with a Society of Thoracic Surgeons (STS) mortality risk score of 4%-8%, “I think you can go either way,” said Frank W. Sellke, MD, at the American Heart Association scientific sessions.

“If a patient is 90 years old and can’t expect to live more than a couple of years, you use TAVR; but if the patient is 55 years old and can expect to live 30 years, I would recommend SAVR,” said Dr. Sellke, professor and chief of cardiothoracic surgery at Brown University in Providence, R.I.

He rattled off four things about TAVR that keep it from being for everyone: periprocedural vascular complications, higher rates of paravalvular leak than with surgery, leaflet thrombosis (a phenomenon with unclear clinical consequences), and undocumented long-term durability.

Dr. Sellke made these comments while discussing the report at the meeting on registry data collected from nearly 6,000 intermediate-risk patients who underwent TAVR or SAVR in Germany during January 2011 through December 2013 and assembled in the German Aortic Valve Registry. During that 3-year period, German TAVR patients could receive either the SAPIEN XT valve or the CoreValve, two TAVR systems that now have been superseded in both Europe and the United States by next-generation systems, SAPIEN 3 and Evolut R.

Limitations of a transthoracic approach

Another factor limiting TAVR is the endovascular approach. The best TAVR results by far have come from using a transfemoral approach for endovascular valve placement, but experts estimate that today at least 10% of patients considered for TAVR have a vascular anatomy that makes the transfemoral TAVR impossible. In the past, when such patients underwent TAVR, it was via either a transapical or transaortic approach (collectively called transthoracic), although additional endovascular entry sites are now being tested.

The limitations of transthoracic TAVR were underscored by results from a prespecified quality-of-life analysis done as part of the PARTNER 2 trial that compared the SAPIEN XT system with SAVR in intermediate-risk patients (N Engl J Med. 2016 April 27;374[17]:1609-20).

Concerns about durability

The durability of TAVR valves is another concern that has recently been influencing patients as they decide between TAVR and SAVR, said Dr. Smith. “A lot of patients don’t want TAVR because of their concerns about its durability.” These patients usually cite evidence reported in May 2016 at the annual congress of the European Association of Percutaneous Cardiovascular Interventions in Paris by Danny Dvir, MD, on longer-term follow-up of 378 patients who underwent TAVR at either of two pioneering centers. A retrospective review suggested a valve degeneration rate of about 50% after 8 years, Dr. Dvir reported.

This report “has gotten a lot of penetration over the Internet, and a lot of patients don’t like the uncertainty” about TAVR durability that this report produced. “A lot of the time now, patients come in with a fixed idea of whether they want TAVR or SAVR,” Dr. Smith said.

Dr. Smith essentially agreed with Dr. Sellke on the current role for TAVR relative to SAVR in lower-risk patients.

“If the patient is clearly intermediate risk, with an STS mortality risk of more than 6% and is at least 80 years old, then they’ll have TAVR 99% of the time. But if it’s a 75 year old with an STS score of 3.2% and otherwise healthy, the best choice is not as clear.”

Another cardiothoracic surgeon with lots of TAVR experience, Michael J. Reardon, MD, has much more enthusiasm for TAVR. “In my practice, I use TAVR exclusively in patients at least 80 years old. I don‘t care how healthy they look,” said Dr. Reardon, professor of cardiovascular surgery at Houston Methodist. He acknowledged that broader use of TAVR for intermediate-risk patients is getting push back from other cardiothoracic surgeons.

Dr. Sellke is one such surgeon, and he called uncertain TAVR valve durability the deciding factor. “We need longer-term data on [TAVR] valve longevity before we routinely put them into intermediate- or low-risk patients,” he said during a panel discussion at the meeting.

Dr. Reardon highlighted that newer TAVR systems have been reducing problems such as paravalvular leaks and the need for pacemakers following placement of self-expanding TAVR valves. Despite these technical improvements, the final frontier for TAVR for lower-risk patients is valve durability, Dr. Reardon said in an interview.

“I’m convinced the durability is there, and that any 80-year-old patient who is anatomically suited for transfemoral TAVR should get it no matter now healthy they look. If their likely survival is 15 years or less, then they are reasonable candidates for TAVR.”

Dr. Sellke had no relevant disclosures. PARTNER 2 was funded by Edwards, the company that markets Sapient TAVR systems. Dr. Cohen had no relevant disclosures. Dr. Smith has been an investigator in the PARTNER studies. Dr. Reardon has been a consultant to Medtronic, the company that markets the CoreValve and Evolut R TAVR systems.

I don‘t care how healthy they look,” said Dr. Reardon, professor of cardiovascular surgery at Houston Methodist. He acknowledged that broader use of TAVR for intermediate-risk patients is getting push back from other cardiothoracic surgeons.

Dr. Sellke is one such surgeon, and he called uncertain TAVR valve durability the deciding factor. “We need longer-term data on [TAVR] valve longevity before we routinely put them into intermediate- or low-risk patients,” he said during a panel discussion at the meeting.

Dr. Reardon highlighted that newer TAVR systems have been reducing problems such as paravalvular leaks and the need for pacemakers following placement of self-expanding TAVR valves. Despite these technical improvements, the final frontier for TAVR for lower-risk patients is valve durability, Dr. Reardon said in an interview.

“I’m convinced the durability is there, and that any 80-year-old patient who is anatomically suited for transfemoral TAVR should get it no matter now healthy they look. If their likely survival is 15 years or less, then they are reasonable candidates for TAVR.”

Dr. Sellke had no relevant disclosures. PARTNER 2 was funded by Edwards, the company that markets Sapient TAVR systems. Dr. Cohen had no relevant disclosures. Dr. Smith has been an investigator in the PARTNER studies. Dr. Reardon has been a consultant to Medtronic, the company that markets the CoreValve and Evolut R TAVR systems.

Patients whose Crohn’s disease fully remits after resection should not wait for endoscopic recurrence to start tumor-necrosis-factor inhibitors or thiopurines, according to a new guideline from the American Gastroenterological Association.

Patients who are low risk or worried about side effects, however, “may reasonably select endoscopy-guided pharmacological treatment,” the guidelines state (doi: 10.1053/j.gastro.2016.10.038).

The AGA made a conditional recommendation against the prophylactic use of budesonide, probiotics, and 5-aminosalicylates such as mesalamine. Only low-quality evidence supports their efficacy after resection, and by using these agents, clinicians may inadvertently boost the risk of recurrence by forgoing better therapies, the guideline states.

The initial endoscopy should be timed for 6-12 months after resection, regardless of whether patients are receiving pharmacologic prophylaxis, the guideline states. If there is endoscopic recurrence, then anti-TNF or thiopurine therapy should be started or optimized.

In the Postoperative Crohn’s Endoscopic Recurrence (POCER) trial, endoscopic monitoring and treatment escalation in the face of endoscopic recurrence cut the risk of subsequent clinical and endoscopic recurrence by about 18% and 27%, respectively, compared with continuing the original treatment regimen. Most patients received azathioprine or adalimumab with 3 months of metronidazole postoperatively, so “even [those] who were already on postoperative prophylaxis benefited from endoscopic monitoring with colonoscopy at 6-12 months,” the guideline notes. However, patients who elect early prophylaxis after resection can reasonably forego colonoscopy if endoscopic recurrence is unlikely to affect their treatment plan, the AGA states. The guideline strongly recommends ongoing surveillance endoscopies if patients decide against early postresection prophylaxis, but notes a lack of evidence on how far to space out these procedures.

CORONADO, CALIF. – Percutaneous gastrostomy with jejunal extension (PEG-J) is an appealing and effective method for delivery of enteral nutrition in necrotizing pancreatitis patients, without the mechanical issues and discomfort associated with nasojejunal (NJ) tube, results from a single-center retrospective study showed.

“The advantages of PEG-J route for enteral nutrition in necrotizing pancreatitis patients must be weighed carefully against the potentially severe complication profile,” study author Alexandra M. Roch, MD, said at the annual meeting of the Western Surgical Association.

“More recently, enteral nutrition has been used, despite a potential for pancreatic stimulation,” she said. “From 16 randomized, controlled trials with 847 patients, it was associated with decreased mortality, decreased infectious complications, decreased length of hospital stay, and a trend toward decreased rate of organ failure. Based on those findings, enteral nutrition has become the standard of care in acute pancreatitis. The optimal enteral nutrition route, however, is still debated. The traditional route is the nasojejunal [NJ] tube. Its placement is noninvasive, but it is associated with discomfort for the patient, dislodgement in 16%-63% of cases, and potentially sinusitis. Conversely, percutaneous gastrostomy with jejunal extension [PEG-J] is beneficial for patient comfort but has the drawbacks of being an invasive procedure with the risk of cellulitis and more severe complications.”

The aim of the current study was to compare the safety and efficacy of NJ tube and PEG-J enteral nutrition delivery before surgical debridement in patients with necrotizing pancreatitis. Dr. Roch and her associates hypothesized that NJ tube and PEG-J would have a similar complication profile. They retrospectively reviewed the medical records of all patients who underwent surgical debridement for necrotizing pancreatitis at Indiana University Medical Center between 2005 and 2015. Patients with exclusive total parenteral nutrition were excluded from the study, as were those who had incomplete data.

Dr. Roch reported results from 242 patients with a mean age of 54 years. More than half (64%) were men and the main etiology was biliary (47%), followed by alcohol (16%). The median duration of preoperative enteral nutrition was 29 days. Of the 242 patients, 187 had an NJ tube only, 25 had PEG-J only, and 30 patients had an NJ tube followed by PEG-J. More than half of PEG-Js were placed under fluoroscopic guidance, while the remaining 41% were placed endoscopically.

In terms of safety, patients in the NJ tube group had a significantly higher rate of all complications, compared with those in the PEG-J group (52% vs. 27%, respectively; P = .0015). Conversely, there was a significantly higher rate of serious complications among patients in the PEG-J group, compared with the NJ group (11% vs. 0%; P less than .0001). The researchers also found that compared with patients in the PEG-J group, those in the NJ group were more prone to mechanical complications such as difficulty to place (5% vs. 0%, respectively), replacement (30% vs. 5.5%), and repositioning (30% vs. 2%), while PEG-J patients were more prone to infectious complications such as skin infections/cellulitis (4% vs. 0%) and perforation/leakage/peritonitis (11% vs. 0%). When they limited the analysis to grade III or IV complications, the mechanism was always the same: early dislodgement from the GI tract. “The presentation ranged from asymptomatic patients to severe peritonitis,” Dr. Roch said. “Two patients out of the six with severe complications required emergent laparotomy.”

In terms of efficacy, the NJ and PEG-J groups were equivalent in achieving enteral nutrition (67% vs. 68%, respectively). There were also no differences between the two groups in nutritional status when assessed by an increase of serum albumin (38% vs. 36%; P = .87), normalization of serum albumin (9% vs. 16%; P = .14), or in the prevalence of infected necrosis (53% vs. 49%; P = .64).

Dr. Roch acknowledged certain limitations of the study, including its single-center, retrospective design. “Furthermore, we are a tertiary care center, and most patients are referred to us late in the course of their disease,” she said. “Finally, no PEG-Js were placed outside of our institution, raising the question of a selection bias. She reported having no financial disclosures.
