Objective;To improve the technique of pancreatoduodenectomy in order to facilitate the managementof complications and direct observation on follow up.Methods;Pancreatoduodenectomy and Child′s method of digestive tract reconstruction was performed in 42 paltents. A blind loop of jejunum 5 to 6 cm in length was constructed beyond the pancreatojejular anastomosis and it was fixed to the subcutaneous tissueof the adjacent abdominal wall.Results;Thirtytwo cases recovered uneventfully,and 10 cases had complications induding pancreatic and biliary leakage and hemorrhage. These complications were successfully treated under direct vision by choledochoscope passed into the blind jejunal loop. This method of observation was used for longtime follow up in 22 cases,and revealed ercurrent tumor(n=5),bile duct stricture(n=4) and bile duct ascariasis(n=1).Conclusions; This operative method did not cause new complicationsand it can be combined with the traditional operation. Postoperatively, direct observation and management of leakage of pancreatojejular anastomosis and biliointestinal anastomosis and hemorrhage can be accomplished, and the anastomoses and pancreatic stump can be directly observed at followup.
