Fatal fulminant pancreatitis after laparoscopic gastric bypass surgery.

Current widespread application of laparoscopic techniques in Roux-en-Y gastric bypass (RYGBP) is making surgical safety an increasingly important issue. We report one case that resulted in death due to postoperative fulminant acute pancreatitis after laparoscopic RYGBP was performed when this procedure was still relatively new in China. The patient was a chronically obese 19-year-old male. Weight loss medications had been ineffective, and preoperative body mass index was 40.7. Preoperative examination revealed moderate steatohepatitis. Laparoscopic RYGBP (LRYGBP) was performed. Early manifestations of clinical shock appeared 13 h after the laparoscopic surgery. A second laparoscopic examination showed small-vessel hemorrhage at the posterior wall of the jejunojejunal anastomosis, with blood clot formation resulting in Roux limb and afferent loop obstruction. Fulminant acute pancreatitis developed in the patient 18 h after the second surgery. The patient died 15 days later from systemic multiorgan insufficiency. LRYGBP (postcolon) is a technically demanding procedure for surgeons who are not experienced in this operation. In addition, surgical tolerance is reduced in morbidly obese patients. Therefore, special care should be taken during surgery, and hemostasis must be achieved at all bleeding sites. Increased perioperative surveillance allows for early detection and management of severe complications.
