Abstract
BackgroundMetabolic and Bariatric Surgery (MBS) is the most effective management for patients with obesity and weight-related medical conditions. Duodenal switch (DS) is a recent MBS procedure with increasing attention in recent years, however the risk of anastomotic or staple line leaks and the lack of efficient surgical expertise hinders the procedure from becoming fully adopted. ObjectivesTo determine the 30-day predictors of leaks following DS and explore their association with other 30-day postoperative complications. SettingMetabolic and Bariatric Surgery Accreditation and Quality Improvement Program database. MethodsPatients who underwent a primary biliopancreatic diversion with DS or single-anastomosis duodenoileostomy with sleeve procedure, categorized as DS, were assessed for 30-day leaks. A multivariable logistic regression was constructed to identify the predictors of leaks. The assessment of postoperative complications arising from leaks was also performed. ResultsA total of 21,839 DS patients were included, of which 177 (.8%) experienced leaks within 30 postoperative days. The most significant predictor of leaks was steroid immunosuppressive use (adjusted odds ratio [aOR] = 3.01, 95% confidence interval [CI] [1.56–5.13], P < .001) and age, with each decade of life associated with a 26% increase in risk (aOR = 1.26, 95% CI [1.09–1.45], P = .001). Operative length was also associated with leaks, with every additional 30 minutes increasing the odds of a leak by 23% (aOR = 1.23, 95% CI [1.18–1.29], P < .001). The occurrence of leaks was correlated with postoperative septic shock (Crude Odds Ratio [COR] = 280.99 [152.60–517.39]) and unplanned intensive care unit (ICU) admissions (COR = 79.04 [56.99–109.59]). Additionally, mortality rates increased 17-fold with the incidence of leaks (COR = 17.64 [7.41–41.99]). ConclusionsLeaks following DS are a serious postoperative complication with significant risk factors of steroid use, prolonged operative time and advanced age. Leaks are also associated with other severe complications, highlighting the need for early diagnosis and intervention along with additional studies to further validate our results.
