Why the study?
Given the increasing worldwide popularity of bariatric surgery, post-operative imaging is frequently encountered in clinical practice, requiring familiarity with expected anatomy and appearances to identify complications.
Familiarity with expected anatomy and imaging appearances following bariatric procedures allows radiologists to identify and manage postoperative complications early.

Bariatric surgery is an effective approach to management of morbid obesity. Given its increasing popularity worldwide, post-operative imaging of patients following bariatric surgery is frequently encountered in clinical practice. In this article we review the physiological principles, normal post-operative anatomy, and imaging appearance of common bariatric procedures (Roux-en-Y gastric bypass, vertical sleeve gastrectomy, and laparoscopic adjustable gastric banding) as well as less common bariatric procedures (including intragastric balloon and biliopancreatic diversion with duodenal switch). Technical considerations and imaging pearls for identifying perioperative and late complications following bariatric procedures will be illustrated through fluoroscopic upper GI studies and computed tomography case examples. Familiarity with expected anatomy and imaging appearances following bariatric procedures allows the radiologist to play a key role in early identification and management of postoperative complications.
