Gastric Bypass: Weight Loss with Complications Abstract. Roux-en-Y gastric bypass (RYGBP) is the most often performed bariatric operation worldwide with internal hernia as one of the main long-term complications. To our knowledge, we report the first case of post-ischemic small-bowel strictures observed after a successful operation of an internal hernia after RYGBP. During emergency surgery a Petersen and a Brolin hernia were diagnosed and repaired. The initially ischemic small intestine was recovered. However, a week later the patient presented herself again due to ischemia-induced small-bowel strictures. These were treated successfully by endoscopic balloon dilatation.
