Introduction: Endoscopy is performed routinely during bariatric surgery. It is often used for provocative testing during Roux-en-Y gastric bypass (RNYGB) and sleeve gastrectomy (SG). Recent publications would indicate about one-quarter of bariatric cases are performed with concurrent endoscopy with a slight increase in time and no increase in complications. Does performing endoscopy decrease complication rates after revisional bariatric surgery (RBS)?
Methods: An analysis of the American College of Surgeons National Surgical Quality Initiative Program (NSQIP) was conducted for the years 2005-2017. Seventeen postoperative outcomes were analyzed. A 1:1 propensity score matching analysis was completed for 13 patient comorbidities and demographics. A McNemar’s test for paired categorical variables and a paired t-test for continuous variables were completed. The results were reported as the frequency and percentage for categorical variables and the mean (+/- standard deviation) for continuous variables. P was significant at 0.05.
Results: A total of 7,249 revisional bariatric surgery (RBS) cases were identified. After propensity score matching for patient comorbidities and demographics 2,329 cases remained. Esophagogastroduodenoscopy (EGD) was performed in 375 (16%) of these patients. There were no differences in complication rates between the two groups.
Conclusions: Endoscopy is performed in about one-sixth of patients undergoing RBS. There is a slight increase in operative time but no difference in 30 day postoperative complications.
