Surgical treatment of chronic pancreatic cholangiopathy.

In a consecutive surgical series of 70 patients with chronic calcifying pancreatitis, 18 presented with fixed stenosis of the terminal common bile duct. Nine patients presented with jaundice and two had a palpable gallbladder. The most relevant laboratory datum in the series was a persistently high serum alkaline phosphatase level. Long tapering of the terminal common bile duct was the characteristic radiological sign in 45 of our patients. In five of the 18 cases compression of the terminal bile duct was due to cephalic pseudocysts. Hepaticojejunostomy-en-Y was the type of drainage chosen in 16 cases, and an end-to-side technique was used in 15 patients. Side-to-side choledochoduodenostomy was performed in two cases. In 14 patients, biliary drainage was associated with other surgical procedures on the pancreatic parenchyma. No postoperative complications due to the biliary drainage occurred in this series.
