Abstract

Retrograde jejuno-jejunal intussusception is a rare complication of bariatric surgeries. It causes acute sudden symptoms that require immediate surgical intervention. We report a case of a 46-year-old female who underwent Roux-en-Y gastric bypass (REYGP) 3 years prior. The patient presented to the emergency department with acute sudden abdominal pain, nausea and vomiting. Laparoscopically, intussuscepting small bowel segment was found gangrenous, and it was resected and end-to-end anastomoses were fashioned. The postoperative course was uneventful, and the patient remained asymptomatic for the 12 months of follow-up. Patients with retrograde intussusception experience an intolerable severe pain that necessitates surgical intervention. The etiology of intussusception as a complication after REYGP is unclear, yet theoretically some possible etiologies exist. The initial diagnosis of retrograde intussusception is made based on abdominal computed tomography. Early intervention significantly reduces morbidity and mortality.
