Abstract:
Small bowel intussusception is an uncommon cause of adult intestinal obstruction after gastric bypass for morbid obesity. It usually affects the Roux or the common limb at the jejunojejunostomy site and is mainly retrograde. An altered motility of the Roux limb seems to be the main explanation for its developement. We report the case of a patient with a late acute anterograde intussusception after a previous distal Roux-en-Y gastric bypass. Clinical, radiological and operative findings are presented and surgical solutions described in the literature are reviewed.
