Objective: Using a prospective randomized study to assess postoperative morbidity and pancreatic function after pancreaticoduodenectomy with pancreaticojejunostomy and duct occlusion without pancreaticojejunostomy. Summary Background Data: Postoperative complications after pancreaticoduodenectomy are largely due to leakage of the pancreaticoenterostomy. Pancreatic duct occlusion without anastomosis of the pancreatic remnant may prevent these complications. Methods: A prospective randomized study was performed in a nonselected series of 169 patients with suspected pancreatic and periampullary cancer. In 86 patients the pancreatic duct was occluded without anastomosis to pancreatic remnant, and in 83 patients a pancreaticojejunostomy was performed after pancreaticoduodenectomy. Postoperative complications were the endpoint of the study. All relevant data concerning patient demographics and postoperative morbidity and mortality as well as endocrine and exocrine function were analyzed. At 3 and 12 months after surgery, evaluation of weight loss, stools, and the use of antidiabetics and pancreatic enzyme was repeated. Results: Patient characteristics were comparable in both groups. There were no differences in median blood loss, duration of operation, and hospital stay. No significant difference was noted in postoperative complications, mortality, and exocrine insufficiency. The incidence of diabetes mellitus was significantly higher in patients with duct occlusion. Conclusions: Duct occlusion without pancreaticojejunostomy does not reduce postoperative complications but significantly increases the risk of endocrine pancreatic insufficiency after duct occlusion.
