PURPOSE OF REVIEW: Morbid obesity is an epidemic in the United States and parts of Europe, with severe health consequences. As the number of patients undergoing bariatric surgery has increased dramatically, it is crucial for the gastroenterologist caring for these patients to have a better understanding of the procedures, their unique complications and the proper management for these complications. RECENT FINDINGS: The incidence of the most significant complications is calculated from recent publications. Radiological and endoscopic workup is useful for diagnosis. Endoscopic dilation of strictures is possible. Endoscopic intervention for selected leaks and fistulas has been reported. SUMMARY: This review describes the most common types of bariatric surgery, discusses the complications that each can cause, and addresses the recommended approach for their work-up and management in order to better equip the gastroenterologist in dealing with this new field.
