Abstract:
Diagnostic imaging features of the most commonly performed types of bariatric surgery, which are gastric banding, sleeve gastrectomy, and Roux-en-Y gastric bypass, are reviewed as well as imaging diagnosis of their complications. Although upper gastrointestinal series remains the first-line imaging test for assessing postoperative anatomy and complications, the important role of multidetector computed tomography in diagnosis of serious complications is highlighted.
