title: History of pancreaticojejunostomy in pancreaticoduodenectomy: development of a more reliable anastomosis technique.
abstract: The history of pancreaticojejunostomy in pancreaticoduodenectomy is described. Many types of operations have been devised in search of a more reliable method of anastomosis. To perform a safe and reliable pancreaticoenteric anastomosis it is necessary to understand the organ characteristics of the pancreas. We investigated factors required for a reliable pancreaticojejunostomy and devised a new surgical technique that meets those requirements. We introduce the theoretical substantiation and clinical usefulness of our new surgical technique while reviewing the history of pancreaticojejunostomy after pancreaticoduodenectomy. The unique aspect of our method is approximation of the pancreas stump and jejunal wall by six to eight interrupted sutures. It is speculated that too many sutures and tying too tight in the anastomosis may cause ischemia and necrosis of the pancreatic stump by restricting the tissue blood flow. Our method allows us not only to reduce the number of sutures, but also to avoid some of the complicated manipulations done in any other existing methods. The newly devised pancreaticojejunostomy is an excellent surgical technique with anastomotic failure seen in only two patients and no deaths out of 162 consecutive patients.
