ASMBS literature review on the treatment of marginal ulcers after metabolic and bariatric surgery.

Abstract

Marginal ulcers (MUs) encompass a group of mucosal disruptions and subsequent inflammatory changes and their sequala found after Roux-en-Y gastric bypass (RYGB) oneanastomosis gastric bypass (OAGB), and, less commonly, after biliopancreatic diversion with duodenal switch (BPD/DS) or single anastomosis duodeno-ileostomy with sleeve gastrectomy (SADI-S). Prevalence of MU after RYGB ranges from .6%-16%. This review summarizes the current knowledge about the treatment options available for MU after MBS for providers who treat them.
