s p n b n m w Laparoscopic Roux-en-Y gastric bypass (RYGB) is the most commonly performed bariatric procedure. A comprehensive preoperative evaluation is performed to detect possible gastrointestinal irregularities. However, except for the duodenum, an assessment of the small bowel is usually not performed. Few reports regarding the management of intraoperative detected pathologies of the small bowel have been published. Adult enteral intussusception is rare. In bariatric patients, this long-term complication usually occurs in the postoperative course. Transient small bowel intussusceptions (TSBIs) are even more uncommon; however, they might be much more frequent than thought owing to their self-limiting presentation.
