Lack of bowel distension is not indicative of a normal study Internal hernias can present with intermittent pain without overt obstruction Key imaging findings on CT can allow early diagnosis of post bariatric complications before symptoms become life threatening  

Bariatric surgery is becoming a commonplace hospital procedure performed in North America. Patients may undergo a number of surgical intervention, including Roux-en-y gastric bypass, sleeve gastrectomy and gastric banding. If complications occur, they often present with bowel obstruction. However, patients can have important abnormalities in the absence of dilated loops. This educational poster will review non-obstructive complications of bariatric surgery which need to be identified early to alleviate symptoms, improve weight loss goals and prevent future ischemic or obstructive complications. This includes: 1. Dehiscence of Roux-en-y of sleeve gastrectomy staple lines 2. Internal hernia through Petersen’s defect without obstruction: Specific focus on a. SMV “beak sign” b. Perpendicular crossing of vessels with respect to bowel loops c. Location and aggregation of bowel loops in abnormal locations 3. Slipped band after restrictive-type banding surgery 4. Malabsorption syndromes
