RESUMO
PURPOSE: Roux-en-Y gastric bypass is a common bariatric procedure. Its configuration creates an excluded gastric remnant, which is subject to potential acute complications such as bleeding, perforation, and necrosis. MATERIAL AND METHODS: A retrospective analysis of a prospective database including all patients presenting between 2007 and 2019 to our institution with acute gastric remnant complications after RYGB was performed. RESULTS: Seven patients were included, including 3 hemorrhages, two of which were treated with double-balloon enteroscopy, as well as 3 perforations and 1 necrosis, all of which required emergent surgery. Overall gastric remnant complication rate was 0.3% in this series. CONCLUSION: Acute gastric remnant complications after RYGB are infrequent, but their diagnosis and management can be challenging. Double-balloon enteroscopy has diagnostic and therapeutic value for selected patients. Emergent surgery remains the standard of care for unstable patients and should not be delayed.
