The European Society of Cardiology guidelines on cardiovascular assessment and management of patients undergoing noncardiac surgery have seen extensive revision since the 2014 version.

They still have the same aim – to prevent surgery-related bleeding complications, perioperative myocardial infarction/injury (PMI), stent thrombosis, acute heart failure, arrhythmias, pulmonary embolism, ischemic stroke, and cardiovascular (CV) death.

Cochairpersons Sigrun Halvorsen, MD, PhD, and Julinda Mehilli, MD, presented highlights from the guidelines at the annual congress of the European Society of Cardiology and the document was simultaneously published online in the European Heart Journal.

The document classifies noncardiac surgery into three levels of 30-day risk of CV death, MI, or stroke. Low (< 1%) risk includes eye or thyroid surgery; intermediate (1%-5%) risk includes knee or hip replacement or renal transplant; and high (> 5%) risk includes aortic aneurysm, lung transplant, or pancreatic or bladder cancer surgery (see more examples below).

It classifies patients as low risk if they are younger than 65 without CV disease or CV risk factors (smoking, hypertension, diabetes, dyslipidemia, family history); intermediate risk if they are 65 or older or have CV risk factors; and high risk if they have CVD.  

In an interview, Dr. Halvorsen, professor in cardiology, University of Oslo, zeroed in on three important revisions:

First, recommendations for preoperative ECG and biomarkers are more specific, he noted.

The guidelines advise that before intermediate- or high-risk noncardiac surgery, in patients who have known CVD, CV risk factors (including age 65 or older), or symptoms suggestive of CVD:

• It is recommended to obtain a preoperative 12-lead ECG (class I).
• It is recommended to measure high-sensitivity cardiac troponin T (hs-cTn T) or high-sensitivity cardiac troponin I (hs-cTn I). It is also recommended to measure these biomarkers at 24 hours and 48 hours post surgery (class I).
• It should be considered to measure B-type natriuretic peptide or N-terminal of the prohormone BNP (NT-proBNP).

However, for low-risk patients undergoing low- and intermediate-risk noncardiac surgery, it is not recommended to routinely obtain preoperative ECG, hs-cTn T/I, or BNP/NT-proBNP concentrations (class III).

Troponins have a stronger class I recommendation, compared with the IIA recommendation for BNP, because they are useful for preoperative risk stratification and for diagnosis of PMI, Dr. Halvorsen explained. “Patients receive painkillers after surgery and may have no pain,” she noted, but they may have PMI, which has a bad prognosis.

Second, the guidelines recommend that “all patients should stop smoking 4 weeks before noncardiac surgery [class I],” she noted. Clinicians should also “measure hemoglobin, and if the patient is anemic, treat the anemia.”

Third, the sections on antithrombotic treatment have been significantly revised. “Bridging – stopping an oral antithrombotic drug and switching to a subcutaneous or IV drug – has been common,” Dr. Halvorsen said, “but recently we have new evidence that in most cases that increases the risk of bleeding.”

“We are [now] much more restrictive with respect to bridging” with unfractionated heparin or low-molecular-weight heparin, she said. “We recommend against bridging in patients with low to moderate thrombotic risk,” and bridging should only be considered in patients with mechanical prosthetic heart valves or with very high thrombotic risk.
 

More preoperative recommendations

In the guideline overview session at the congress, Dr. Halverson highlighted some of the new recommendations for preoperative risk assessment.  

If time allows, it is recommended to optimize guideline-recommended treatment of CVD and control of CV risk factors including blood pressure, dyslipidemia, and diabetes, before noncardiac surgery (class I).

Patients commonly have “murmurs, chest pain, dyspnea, and edema that may suggest severe CVD, but may also be caused by noncardiac disease,” she noted. The guidelines state that “for patients with a newly detected murmur and symptoms or signs of CVD, transthoracic echocardiography is recommended before noncardiac surgery (class I).

“Many studies have been performed to try to find out if initiation of specific drugs before surgery could reduce the risk of complications,” Dr. Halvorsen noted. However, few have shown any benefit and “the question of presurgery initiation of beta-blockers has been greatly debated,” she said. “We have again reviewed the literature and concluded ‘Routine initiation of beta-blockers perioperatively is not recommended (class IIIA).’ “

“We adhere to the guidelines on acute and chronic coronary syndrome recommending 6-12 months of dual antiplatelet treatment as a standard before elective surgery,” she said. “However, in case of time-sensitive surgery, the duration of that treatment can be shortened down to a minimum of 1 month after elective PCI and a minimum of 3 months after PCI and ACS.”
 

Patients with specific types of CVD

Dr. Mehilli, a professor at Landshut-Achdorf (Germany) Hospital, highlighted some new guideline recommendations for patients who have specific types of cardiovascular disease.

Coronary artery disease (CAD). “For chronic coronary syndrome, a cardiac workup is recommended only for patients undergoing intermediate risk or high-risk noncardiac surgery.”

“Stress imaging should be considered before any high risk, noncardiac surgery in asymptomatic patients with poor functional capacity and prior PCI or coronary artery bypass graft (new recommendation, class IIa).”

Mitral valve regurgitation. For patients undergoing scheduled noncardiac surgery, who remain symptomatic despite guideline-directed medical treatment for mitral valve regurgitation (including resynchronization and myocardial revascularization), consider a valve intervention – either transcatheter or surgical – before noncardiac surgery in eligible patients with acceptable procedural risk (new recommendation).

Cardiac implantable electronic devices (CIED). For high-risk patients with CIEDs undergoing noncardiac surgery with high probability of electromagnetic interference, a CIED checkup and necessary reprogramming immediately before the procedure should be considered (new recommendation).

Arrhythmias. “I want only to stress,” Dr. Mehilli said, “in patients with atrial fibrillation with acute or worsening hemodynamic instability undergoing noncardiac surgery, an emergency electrical cardioversion is recommended (class I).”

Peripheral artery disease (PAD) and abdominal aortic aneurysm. For these patients “we do not recommend a routine referral for a cardiac workup. But we recommend it for patients with poor functional capacity or with significant risk factors or symptoms (new recommendations).”

Chronic arterial hypertension. “We have modified the recommendation, recommending avoidance of large perioperative fluctuations in blood pressure, and we do not recommend deferring noncardiac surgery in patients with stage 1 or 2 hypertension,” she said.
 

Postoperative cardiovascular complications

The most frequent postoperative cardiovascular complication is PMI, Dr. Mehilli noted.

“In the BASEL-PMI registry, the incidence of this complication around intermediate or high-risk noncardiac surgery was up to 15% among patients older than 65 years or with a history of CAD or PAD, which makes this kind of complication really important to prevent, to assess, and to know how to treat.”

“It is recommended to have a high awareness for perioperative cardiovascular complications, combined with surveillance for PMI in patients undergoing intermediate- or high-risk noncardiac surgery” based on serial measurements of high-sensitivity cardiac troponin.

The guidelines define PMI as “an increase in the delta of high-sensitivity troponin more than the upper level of normal,” Dr. Mehilli said. “It’s different from the one used in a rule-in algorithm for non-STEMI acute coronary syndrome.”

Postoperative atrial fibrillation (AFib) is observed in 2%-30% of noncardiac surgery patients in different registries, particularly in patients undergoing intermediate or high-risk noncardiac surgery, she noted.

“We propose an algorithm on how to prevent and treat this complication. I want to highlight that in patients with hemodynamic unstable postoperative AF[ib], an emergency cardioversion is indicated. For the others, a rate control with the target heart rate of less than 110 beats per minute is indicated.”

In patients with postoperative AFib, long-term oral anticoagulation therapy should be considered in all patients at risk for stroke, considering the anticipated net clinical benefit of oral anticoagulation therapy as well as informed patient preference (new recommendations).

Routine use of beta-blockers to prevent postoperative AFib in patients undergoing noncardiac surgery is not recommended.

The document also covers the management of patients with kidney disease, diabetes, cancer, obesity, and COVID-19. In general, elective noncardiac surgery should be postponed after a patient has COVID-19, until he or she recovers completely, and coexisting conditions are optimized.

The guidelines are available from the ESC website in several formats: pocket guidelines, pocket guidelines smartphone app, guidelines slide set, essential messages, and the European Heart Journal article.
 

Noncardiac surgery risk categories

The guideline includes a table that classifies noncardiac surgeries into three groups, based on the associated 30-day risk of death, MI, or stroke:

• Low (< 1%): breast, dental, eye, thyroid, and minor gynecologic, orthopedic, and urologic surgery.
• Intermediate (1%-5%): carotid surgery, endovascular aortic aneurysm repair, gallbladder surgery, head or neck surgery, hernia repair, peripheral arterial angioplasty, renal transplant, major gynecologic, orthopedic, or neurologic (hip or spine) surgery, or urologic surgery
• High (> 5%): aortic and major vascular surgery (including aortic aneurysm), bladder removal (usually as a result of cancer), limb amputation, lung or liver transplant, pancreatic surgery, or perforated bowel repair.

The guidelines were endorsed by the European Society of Anaesthesiology and Intensive Care. The guideline authors reported numerous disclosures.

Practice has gone back and forth on whether atrial fibrillation (AFib) should be considered in the preoperative cardiovascular risk (CV) evaluation of patients slated for noncardiac surgery, and the Revised Cardiac Risk Index (RCRI), currently widely used as an assessment tool, doesn’t include the arrhythmia.

But consideration of preexisting AFib along with the RCRI predicted 30-day mortality more sharply than the RCRI alone in an analysis of data covering several million patients slated for such procedures.

ECG_Electrocardiogram_web.jpg

• 1.31 (95% CI, 1.30-1.33) for heart failure
• 1.40 (95% CI, 1.37-1.43) for stroke
• 1.59 (95% CI, 1.43-1.75) for systemic embolism
• 1.14 (95% CI, 1.13-1.16) for major bleeding  
• 0.81 (95% CI, 0.79-0.82) for MI

Those with preexisting AFib also had longer hospitalizations at a median 5 days, compared with 4 days for those without such AFib (P < .001).

The study has the limitations of most any retrospective cohort analysis. Other limitations, the report notes, include lack of information on any antiarrhythmic meds given during hospitalization or type of AFib.

For example, AFib that is permanent – compared with paroxysmal or persistent – may be associated with more atrial fibrosis, greater atrial dilatation, “and probably higher pressures inside the heart,” Dr. Mentias observed.

“That’s not always the case, but that’s the notion. So presumably people with persistent or permanent atrial fib would have more advanced heart disease, and that could imply more risk. But we did not have that kind of data.”

Dr. Mentias and Dr. Prasada report no relevant financial relationships; disclosures for the other authors are in the report. Dr. Curtis discloses serving on advisory boards for Abbott, Janssen Pharmaceuticals, Sanofi, and Milestone Pharmaceuticals; receiving honoraria for speaking from Medtronic and Zoll; and serving on a data-monitoring board for Medtronic. Dr. Korada reports he has no relevant financial relationships.

“That’s not always the case, but that’s the notion. So presumably people with persistent or permanent atrial fib would have more advanced heart disease, and that could imply more risk. But we did not have that kind of data.”

Dr. Mentias and Dr. Prasada report no relevant financial relationships; disclosures for the other authors are in the report. Dr. Curtis discloses serving on advisory boards for Abbott, Janssen Pharmaceuticals, Sanofi, and Milestone Pharmaceuticals; receiving honoraria for speaking from Medtronic and Zoll; and serving on a data-monitoring board for Medtronic. Dr. Korada reports he has no relevant financial relationships.

BALTIMORE – A large retrospective study found that laparoscopic repair of umbilical hernias in patients with obesity resulted in lower rates of wound complications than open repair even though the laparoscopic group had higher body mass index and rates of other key comorbidities, according to results reported at the annual meeting of the Society of American Gastrointestinal and Endoscopic Surgeons.

“In patients with obesity, even though our laparoscopic umbilical hernia repair [UHR] group had an overall higher BMI; higher rates of diabetes, hypertension, and current smoking status; and longer operative times, they experienced decreased postoperative wound complications, compared to the open-repair group,” said Kristen Williams, MD, of TriHealth in Cincinnati.

The retrospective cohort study evaluated 12,026 adult patients with a BMI of more than 30 kg/m² in the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database who had UHR in 2016. Almost four times as many patients had open rather than laparoscopic surgery (9,695 vs. 2,331, respectively)

Dr. Williams noted that two previous studies reported lower wound infection rates after laparoscopic hernia repair in patients with obesity: an analysis of ventral, not just umbilical, hernia repair based on the NSQIP database from 2009-2012 (Am J Surg. 2015;210:1029-30) and a single-institution retrospective chart review from 2003-2009 of patients who had umbilical hernia repair (Am J Surg. 2013;205:231-6). “In our study we wanted to compare the rate of postoperative complications after laparoscopic vs. open umbilical hernia repairs in patients with obesity based on NSQIP review,” she said.

The rate of composite surgical-site infections in the open group was 1.9% vs. 1.1% in the laparoscopic group (P less than .01), Dr. Williams noted. “SSI was statistically significantly higher in the open-repair group, and there was a trend toward higher deep SSI in the open group [0.3% vs. 0.1%; P = .147],” she said. Laparoscopic patients had significantly higher rates of postoperative pneumonia (0.4% vs 0.1%; P = .012), but Dr. Williams noted this was only significant in the non–elective surgery group. Operative times were significantly longer in the laparoscopic repair group (70 vs. 44 minutes). “The literature shows that longer operative times are associated with higher rates of SSI,” Dr. Williams added. “However our laparoscopic group still had lower rates of composite SSI.”

“Logistic regression was utilized and found that morbidity, defined as superficial, deep, and organ-space SSIs, was significantly increased in the open-repair group,” Dr. Williams said.

A higher percentage of patients in the laparoscopic group were women than in the open group (29.4% vs. 24.4%; P less than .001). The laparoscopic group had statistically significant higher average BMI (37.5 vs. 36.1; P less than .001) and higher rates of smoking (18.6% vs. 16.5%; P = .018), diabetes (18.4% vs. 15.8%; P = .002), and hypertension (47.5% vs. 43.8%; P = .001) than the open group.

The study also analyzed outcomes by BMI class. “As BMI class increased, superficial SSI, deep SSI, return-to-OR rates, postoperative pneumonia rates, and composite SSI increased in the open-repair group, indicating that higher BMI is associated with higher rates of complications in the open-repair group,” Dr. Williams said. Likewise, as obesity class increased, so did operative times in both the open and laparoscopic groups, she added.

She also noted that this study reported a significant increase in the proportion of laparoscopic UHRs than did a retrospective cohort study of 2009 and 2010 NSQIP files of UHR (Surg Endosc. 2014;28:741-6), 19.4% in this study versus 10.5% in that one.

BALTIMORE – An analysis of malpractice claims paid for hernia operations found that breach of informed consent was a reason for more than 15% of cases, and intraoperative damage to surrounding structures was the leading reason for such lawsuits, according to research presented at the annual meeting of the American Gastrointestinal and Endoscopic Surgeons.

The purpose of the study was to identify leading causes of litigation for hernia repair as the volume of hernia repairs in the United States increases with a trend toward minimally invasive and robotic surgery, said Asad Choudhry, MBBS, of the State University of New York, Syracuse.“In terms of the hernia itself, inguinal hernia operations were found to be the most common hernia procedure that led to pursuance of litigation, and laparoscopy was the most common type of procedure rather than open in terms of patients pursuing litigation.”

The study sampled the WestLawNext legal database for medical malpractice abdominal wall procedures, and evaluated 430 cases of abdominopelvic wall hernias that fit the study criteria – inguinal, femoral, ventral, umbilical, parastomal, spigelian, obturator, epigastric, incisional, paraumbilical, and pantaloon hernias, Dr. Choudhry said. Hiatal, diaphragmatic, sciatic, gluteal, and lumbar hernias were excluded. He noted that abdominal wall hernia have been reported to be the second most common abdominopelvic procedure performed in the United States after C-section, with more than 1 million procedures done annually (Surg Clin N Am. 2003;83:1045-51).

While most malpractice hernia cases were decided in favor of the defendant surgeon, settlements and cases with a jury verdict in favor of the plaintiff were costly. Dr. Choudhry cited awards of $6.8 million, $12 million, and $3 million in specific hernia cases.

“In terms of the type of repair itself, elective operations were more common, and mesh was used in approximately 27% of cases in which there was a defendant verdict and 18% of cases in which there was a plaintiff verdict,” he said.

For inguinal hernia, 61% of cases were decided for the defendant surgeon. With regards to type of procedure, laparoscopic surgery resulted in defendant verdicts in 31% of cases versus 23% for the plaintiff, and open operations resulted in a ruling favoring the defendant surgeon in 26% versus 15% for the plaintiff. (The remainder were lap-converted-to-open operations, with 2% for the defendant and 1% for the plaintiff.)

Mortality was a key determinant of verdict, Dr. Choudhry added. “Cases with no mortality were more likely of having an outcome in favor of the defendant surgeon.”

The researchers also looked at litigation arising from the phase of care – before, during, or after surgery. “In the preoperative time setting, delay or failure to diagnose or manage a hernia was the leading cause of malpractice,” Dr. Choudhry said. “These cases were mainly emergent patients presenting to the emergency department where the intervention was not performed in a timely manner and leading to some form of complication.”

In the intraoperative period, damage to surrounding structures was by far the leading cause of malpractice, but incomplete procedure or improper surgical technique and use of improper surgical materials also were significant causes in this period. Postoperatively, failure to timely detect and/or repair a surgical complication was the most common cause of litigation. “However, it’s important to note that persistent pain, such as nerve entrapment syndrome, is also noted in the postoperative time period as a cause of litigation,” he added.

The study also evaluated injury severity in the context of a claim outcome. “Most claims where there was an insignificant or minor injury were decided for the defendant surgeon,” Dr. Choudhry said. “But as you start moving higher on the injury scale toward death, these cases were more likely to favor the plaintiff, and that’s correlative because patients tend to sue more when there’s a more significant complication, such as when there’s a death of a family member.” In cases involving death, 41% resulted in a verdict for the defendant surgery, 35% in a plaintiff verdict, and 23% in a settlement, whereas in cases involving insignificant temporary injury, 90% were ruled for the defendant surgeon, with none going to settlement.

The research also found another mitigating factor in malpractice lawsuits: the number of lawyers in a state. “We noted that specific states such as California, New York, Texas, and Florida were bound to have a higher number of lawsuits per population, and this was correlative with the number of lawyers practicing within that state,” Dr. Choudhry said. New York led the nation with 46 cases, followed by California with 42, Florida with 27 ,and Texas and Pennsylvania with 17 each.

Session moderator Heather Logghe, MD, of Jefferson Medical College, Philadelphia, questioned Dr. Choudhry on how surgeons can improve their informed consent process to protect against potential litigation.

“The most important thing we can do is document and explain the risk, benefits, and alternatives, and use an inclusive informed consent that will allow the patients to have a complete understanding of the procedure that is to be done and the complications that may result,” he said. This process needs to be tailored to individual hospital systems. “This may allow for better documentation, and it may not decrease the number of malpractice lawsuits but it may decrease the outcomes not in favor of physicians.”

The researchers also identified trends in the broader context of medical malpractice. Citing data from the National Practitioner Data Bank, Dr. Choudhry noted that malpractice payouts have been increasing since 2012 after a steady 9-year decline. In addition, general surgeons are at greater risk than all but two other types of specialists – neurosurgeons and thoracic-cardiovascular surgeons (N Engl J Med. 2011;365:629-36). “Fifteen percent of general surgeons will be facing malpractice claims annually across the United States. Physicians in high-legal-risk specialties, such as the surgical specialties, are 99% likely to face a claim over their careers.”

The next step for the researchers is to use malpractice insurance data to study medical liability on a larger scale and identify methods physicians can use to improve patient care and mitigate risk, Dr. Choudhry said.

Dr. Choudhry had no relevant financial relationships to disclose.

LAS VEGAS – Colorectal surgeon Jamie Cannon, MD, doesn’t think there’s a rivalry between laparoscopic surgery and robotic surgery. Instead, she told colleagues, they should be seen as parts of the same whole: “Robotics is laparoscopy. It’s just a tool that allows us to do laparoscopic surgery better.”

"Quality improvement is not a static process. It requires constant reassessment to make sure you’re doing a good job,” said Michael J. Rosen, MD, director of the Cleveland Clinic Comprehensive Hernia Center, in a presentation at the Annual Minimally Invasive Surgery Symposium by Global Academy for Medical Education.

It’s worth raising questions since much of the data regarding surgical risks “does not come from hernia patients,” he said. “It’s extrapolated from other surgeries and might not be applicable.”

Dr. Rosen was careful to tell the audience that he’s not an apologist for tobacco users. He listed the downsides of lighting up, including harms to pulmonary function, cardiovascular function, immune response, tissue healing,and hepatic metabolism of drugs. “I’m not crazy. I know that smoking is not healthy,” he said, “and I don’t work for a tobacco company.”

But do current smokers actually pay a price in terms of hernia repair complications? Dr. Rosen and his colleagues examined the question in a 2019 study that matched two groups of 418 ventral hernia repair patients (Surgery. 2019 Feb;165[2]:406-11).

They found no statically significant difference between current smokers and never-smokers in surgical site infections, surgical site occurrences requiring procedural intervention, reoperation, and 30-day morbidity. Seromas were more common in smokers, however (5.5% vs. 1.2%; P = .0005)

Two recent studies warned about risks in current smokers who undergo hernia operations. But, Dr. Rosen said, they actually revealed minimal differences in hernia outcomes between never-smokers and current smokers (Am J Surg. 2018 Sep;216[3]:471-4; Surg Endosc. 2017 Feb;31[2]:917-21).

Tobacco use as a risk factor for hernia complications “might not be as bad as we thought it was, at least for wound morbidity,” he said. “It might not be necessary to cancel the case” because of smoking habits, he said, adding that “you should question canceling folks.”

However, he said, amount of smoking and complexity of the operations still are important factors to consider.

In his presentation, Dr. Rosen questioned another common standard in hernia procedures: The use of postoperative epidurals in elective ventral hernia repair.

He coauthored a 2018 study that compared two matched groups of hernia patients – 763 who received epidurals and 763 who did not. Patients who received epidurals had longer length of stay (5 days vs. 4 days) and higher postop complications (26% vs. 21%; P less than .05; Ann Surg. 2018 May;26[5]:971-6). Epidurals also were linked to worse outcomes in a subset of high-risk pulmonary patients.

Factors such as high rate of improper placement, extra fluid received, and Foley catheter and thromboprophylaxis issues may explain the higher rates of problems in epidurals, he said.

According to Dr. Rosen, a study into an alternative treatment, transversus abdominis plane block, is underway.

LAS VEGAS – Smoking cessation is mandatory before many hernia operations. Now, a surgeon is urging colleagues to examine the evidence and question whether this standard should still stand.

"Quality improvement is not a static process. It requires constant reassessment to make sure you’re doing a good job,” said Michael J. Rosen, MD, director of the Cleveland Clinic Comprehensive Hernia Center, in a presentation at the Annual Minimally Invasive Surgery Symposium by Global Academy for Medical Education.

It’s worth raising questions since much of the data regarding surgical risks “does not come from hernia patients,” he said. “It’s extrapolated from other surgeries and might not be applicable.”

Dr. Rosen was careful to tell the audience that he’s not an apologist for tobacco users. He listed the downsides of lighting up, including harms to pulmonary function, cardiovascular function, immune response, tissue healing,and hepatic metabolism of drugs. “I’m not crazy.

Information obtained from computed tomography (CT) scans may help predict reherniation and surgical site infection (SSI) in patients who had complex ventral hernia repair with the component separation technique (CST), according to findings published in Hernia.

Surgeon_operating_web.jpg

In a study of 65 adults who had a CT performed before CST, visceral fat volume was a significant predictor of reherniation (P = .025, odds ratio 1.65), reported Harm Winters of the department of plastic and reconstructive surgery at Radboud University Medical Center, Nijmegen, the Netherlands, and coauthors.

Patients were 18-75 years of age, and had complex ventral hernia repair via CST between 2000 and 2013. Patients were excluded if the CT scan was performed earlier than 6 months before hernia repair, or if the scan did not cover the full abdomen.

Visceral fat volume, subcutaneous fat volume, loss of domain, rectus thickness and width, abdominal volume, hernia sac volume, total fat volume, sagittal distance, and waist circumference were measured. Mesh reinforcement during surgery was used in 45 patients (69.2%), the authors noted.

Hernia sac volume and subcutaneous fat volume per 1,000 cm³ were significant predictors of surgical site infection (P = .020, OR 2.10 and P = .034, OR 0.26, respectively).

“These findings suggest that CT measurements are a valuable tool for preoperative risk assessment in patients undergoing complex ventral hernia repair using the CST,” the researchers wrote. Future trials should “further identify the role of these CT scan-derived body morphometrics for patient-tailored risk assessment,” they concluded.

No conflicts of interest were reported.

LAS VEGAS – Ajita Prabhu, MD, is intrigued enough by robotic inguinal hernia surgery to study it extensively. Her verdict: In general, it’s just not ready for prime time.

138875_photo_web.jpg

“Right now, I don’t think I have any compelling evidence to tell a laparoscopic surgeon with good surgical times and good outcomes to convert to robotic surgery,” said Dr. Prabhu, an associate professor of surgery at the Cleveland Clinic Foundation, in a presentation the Annual Minimally Invasive Surgery Symposium by Global Academy for Medical Education.

According to Dr. Prabhu, the number of robotic inguinal hernia surgeries in the United States has shot up over the past 8 years, but research into the technique has remained sparse and retrospective.

“There’s not a lot out there,” she said. “If I stood here and went through every one of those studies detail by detail, I think I could do it in 15 minutes.”

It is true, she said, that robotic surgery has possible advantages, such as better ergonomics for surgeons and, perhaps, a shorter learning curve than laparoscopy. Still, she said, “for those of us who grew up on it [laparoscopy], it’s a lot less hassle for us to get in and get out and get the job done,” even though the technique can hard to both learn and teach.

Robotic surgery has some disadvantages too, she said. “We’re finding additional evidence that it adds OR [operating room] time, and it’s expensive.” She pointed to an analysis that determined the average total cost for robotic unilateral inguinal hernia repair is $5,517 versus $3,269 for laparoscopic procedures (P less than .001). The cost difference is driven by fixed costs, particularly medical device expenses (Surg Endosc. 2018 Dec 7. doi: 10.1007/s00464-018-06606-9).

Moving forward, she said, robotic inguinal hernia surgery should be tested so “we can make sure it’s actually better, not just cool. We need to be able to justify our utilization.”

To that end, a multicenter, randomized, controlled study is now comparing robotic with laparoscopic surgery in inguinal hernias with 50 patients in each group, Dr. Prabhu said. Her institution, Cleveland Clinic Foundation, is one of the centers in the study (www.clinicaltrials.gov/ct2/show/NCT02816658).

In an interview, Dr. Prabhu said the study just finished enrollment; publication is expected within the next few months.

Dr. Prabhu disclosed relationships with Intuitive Surgical (research support and honoraria), Bard Davol (honoraria) and Medtronic (advisory board).

Management of ventral hernia repair in women of childbearing age should include counseling about and consideration of potential impact of pregnancy on recurrence, concluded the authors of a systematic review of the literature on hernia and pregnancy.

pregnant woman IV solution_web.jpg

Erling Omoa, MD, of Bispebjerg Hospital and the University of Copenhagen, and his colleagues surveyed 5,189 articles and chose four cohort studies, four case-control studies, and one case-series study that met their criteria of quality, comparability, and outcomes data. Only randomized, controlled trials, analytical observational studies, and large case series were included. The focus was primary ventral (umbilical and epigastric) and incisional hernia surgery before, during, and after pregnancy.

“The prevalence of clinically relevant primary ventral hernias is very low during pregnancy,” the investigators wrote, but there is a lack on consensus concerning the management of hernia repair in women of childbearing age. “The objective of this systematic review was to examine the risk of recurrence following prepregnancy ventral hernia repair, and secondly, to evaluate the prevalence of ventral hernia during pregnancy and the risk of surgical repair before and after childbirth,” they wrote.

The reviewers evaluated pregnancy following ventral hernia repair as a potential risk factor for hernia recurrence. One study found that subsequent pregnancy was associated with a 1.6-fold increased risk of recurrence. Another found that pregnancy was independently associated with a 73% raised risk of recurrence. The risk of recurrence was no different between mesh and suture repair.

The review found the prevalence of primary ventral and inguinal repair during pregnancy to be low. A single-center cohort study of 20,714 pregnant women of which 17 (0.08%) had umbilical hernias and none of these required repair before delivery. A case series of 126 women who underwent this surgery during pregnancy indicated that this procedure was associated with minimal 30-day morbidity and no deaths. No data was available on fetal morbidity or recurrence in this case series.

Case-control studies reporting on umbilical repair concomitant with elective C-section found that, although adding hernia repair to the procedure increased operative time in some studies, there was no additional complication risk.

Overall, the investigators found several areas in which evidence remains weak, such as the long-term risks for recurrence following pregnancy and long-term outcomes of mesh versus suture repairs. They recommended that patients be counseled on the risk of recurrence linked to subsequent pregnancies and that, if possible, ventral hernia repair should be postponed until after a last planned pregnancy. Watchful waiting until after a delivery was deemed safe in many cases.

The investigators reported no conflicts.
