We present the case of a 41-year-old female who underwent a laparoscopic gastric bypass 8 years prior to her admission to the emergency room, where she arrived complaining of severe and colicky epigastric abdominal pain. The abdominal computed tomography showed a jejuno-jejunal intussusception, for which the patient underwent urgent exploratory laparotomy with intussusception reduction. Intestinal intussusception is a possible postoperative complication of a Roux-en-Y gastric bypass.esMedicineExploratory laparotomyAnastomosisGastric bypassIntussusception (medical disorder)LaparotomySurgeryRoux-en-Y anastomosisGynecologyGeneral surgeryarticle
