Complications of bariatric surgery are increasingly recognized on postoperative CT scans. This exhibit will review the CT findings of complications of bariatric surgery to aid in making a confident diagnosis. Upper gastrointestinal fluoroscopic correlation will be provided in selected cases.

Examples of the following complications will be included but are not limited to: 1. Anastomotic leak 2. Anastomotic stricture 3. Small bowel obstruction due to adhesions, internal hernia and intussusception 4. Staple line dehiscence 5. Afferent loop syndrome 6. Blind pouch syndrome at the jejunojenustomy 7. Bezoars 8. Mesocolic constriction of the roux limb 9. Postoperative collection (hematoma and abscess) 10. Band slippage, erosion and malplacement

TEACHING POINTS: 1. Review CT appearances of various postoperative complications 2. Highlight imaging clues to allow for confident diagnosis 3. Differentiate normal post surgical findings from pathologic conditions CONCLUSIONS: The increased performance of bariatric surgery warrants a better understanding of postsurgical anatomy and the CT appearance of complications. After of this review, the radiologist will be more confident recognizing various complications of bariatric surgery on CT scan.
