[Prevention of pancreatic fistula after pancreaticoduodenectomy by pancreaticojejunostomy plus invagination of pancreatic stump].

Pancreaticoduodenectomy was performed without operative mortality in 118 patients between 1980-1990 by the improved method of pancreaticojejunostomy with the invagination of pancreatic stump. Pancreatic fistula occurred in 3 patients (2.5%) vs. 15.2% in the past, which healed up 41, 49, and 63 days after, respectively. Follow-up studies that include B Ultrasound, CT, PA-BA. 14CO2 breath test and fecal fat elevation were performed in 74 patients (63%) after one year of the operation. No patients suffered from chronic pancreatitis. The improved anastomosis between pancreas and jejunum not only decreased the incidence of pancreatic fistula, but also avoided the occurring of chronic pancreatitis as the result of pancreatic duct stenosis.
