Retrograde intussusception is a rare complication of gastric bypass. It is commonly located in the common limb close to the jejunojejunostomy. The management of such condition dictates the outcome of the patient either in the immediate emergency setting or in the long-term bariatric surgery’s expected results. We present a case of a retrograde intussusception 3 years after gastric bypass which warranted an emergency enterectomy, followed by an anastomotic fistula. The adequate management of these cases leads to recovery without compromising the effect of bariatric surgery in the future.
