Abstract:
The rising prevalence of obesity has led to a substantial investment in the advancement of treatment options for the disease and its comorbid conditions including lifestyle, pharmacologic, and procedural interventions. In this study, we describe a patient with a history of Roux-en-Y gastric bypass who was diagnosed with ischemic jejunitis on upper endoscopy because of the development of an internal hernia, a known late complication of bariatric surgery. This case highlights the diagnostic utility of endoscopy in postgastric bypass complications and the need for safer alternatives to surgery that have the potential to achieve significant weight loss such as bariatric endoscopic therapies.
