Intussusception after Roux-en-Y gastric bypass

Intussusception is a common pediatric surgical problem. Its occurrence in adults is rare and usually involves a specific lead point such as a small bowel tumor or other mass. We describe two adults who developed intussusception after Roux-en-Y gastric bypass. Signs and symptoms of small bowel obstruction were seen in both of these patients, but the responsible pathology was unusual. Because of the increasing frequency with which these gastric bypass procedures are being performed, a high index of suspicion must be employed when dealing with these postoperative patients who present with abdominal complaints.
