In order to avoid lesion of adjacent organs which were often occurred after routine cryotherapy of pancreanoduodinal area, a new cryosurgical method of isolated pancreano-duodinal area was designed for treatment of neoplasm in this area, the feasibility of this method was tried in four pigs.After bile common duct, tail of pancreas, stomach, and jejunum were divided and protected by dry cotton pad, the isolated pancreano-duodinal area was twice fozen to -170℃, maintaining ten minutes with LCS 2000 cryogenic surgical system, then alimentary tract was reconstructed with cholecystojejunostomy and gastroenterostomy. Animals were observed for 1-4 weeks. There was only transient elevation of amylase postoperation and the liver function and blood sugar remained normal. No any complication was seen except a small pseudocyst in lesser omentum. Thorough destruction of pancreatic tissue by enough deep and time course of cryotherapy was emphasized and some technic problem also were discussed. Based on our experiment, cryosurgery of isolated pancreano-duodenum will be considered as a safe and effect therapy of pancreano-duodinal neoplasm.
