Abstract
Gastric bypass is currently the operation of choice for surgical management of morbid obesity. Prompt and accurate radiological diagnosis in the early postoperative period is critical for proper management of suspected gastrojejunal anastomotic leakage, abscess formation, and acute distension of the excluded stomach and afferent loop. Inadequate weight loss may indicate an increase in the gastric pouch and anastomosis or dehiscence of the staple line. Gastric and jejunal ulceration and anastomotic narrowing also require radiological and endoscopic evaluation.
