A rare complication of laparoscopic Roux-en-Y gastric bypass: case report of gastric remnant necrosis.

Gastric remnant necrosis is a very rare, but potential life-threatening complication after laparoscopic Roux-en-Y gastric bypass (LRYGB). We report a case of gastric remnant necrosis that was complicated by peritonitis and resulted in septic shock in a 49-year-old woman who had undergone a LRYGB three months prior to admission. An emergent laparoscopy with subtotal gastrectomy was performed. The patient was treated for septic shock and could leave the hospital in a good condition. Potential etiological factors for gastric remnant necrosis were elaborated.
