Abstract
The incidence of obesity nationwide has led to an increase in both medicinal and surgical interventions, with recent studies indicating a drop in obesity prevalence for the first time in over a decade. Laparoscopic Roux-en-Y gastric bypass remains one of the most commonly performed bariatric procedures in the United States, accounting for about 22% of all bariatric surgeries in 2022. While considered a safe procedure, gastric bypass results in an anatomic configuration that poses a unique challenge from both a surveillance and interventional standpoint. The gastric remnant, biliopancreatic (BP) limb, and extrahepatic biliary tree are not readily accessible vis-à-vis esophagogastroduodenoscopy and thus require a novel approach for evaluation. Symptomatic small bowel diverticula are by themselves a rare entity. When present in the gastric bypass patient, this combination makes for a uniquely challenging case for both diagnosis and management. Surgical exploration with or without intraoperative endoscopy may be the only modality for both localization and management of symptomatic small bowel diverticula in this patient population.
