BACKGROUND: Endoscopy is performed routinely during bariatric surgery. It is often used for provocative testing and intraluminal inspection 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, resulting in a slight increase in time but no increase in complications within 30 days compared with cases where no endoscopy is performed. Do these results persist for endoscopy during 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 in this database. 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, with a significant P value of 0.05. The results were reported as the frequency and percentage for categorical variables and the mean (± standard deviation) for continuous variables.
RESULTS: A total of 7249 RBS cases were identified. After propensity score matching for patient comorbidities and demographics 2329 cases remained. Esophagogastroduodenoscopy (EGD) was performed in 375 (16%) of these patients. There were no differences in complication rates between the two groups.
CONCLUSIONS: Similar to non-revisional bariatric surgery, there is no difference in 30-day postoperative complications when endoscopy is performed in RBS. Endoscopy is performed in about one-sixth of RBS cases.
