Abstract
A total of 40 patients with pancreatitis had associated extrahepatic biliary obstruction. Eighteen had biliary-induced pancreatitis. Comprehensive correction of the biliary tract disease, including cholecystectomy, common duct exploration and, when indicated, transduodenal sphincteroplasty, resulted in a high recovery rate (83%) with no recurrence of pancreatitis. Twenty-two patients had chronic pancreatitis with involvement of the terminal biliary tract by a long tapering stenosis. Nineteen of these patients had chronic fibrocalcific pancreatitis secondary to chronic alcohol abuse. In five patients, the stenosis produced a high grade obstruction which required biliary bypass with choledochoduodenostomy (four) or cholecystoduodenostomy (one). The remaining 14 patients maintained patency of the biliary tract following correction of the underlying pancreatic pathology. The latter consisted of drainage (nine) or resection (five) of 14 associated pseudocysts (present in 64% of the 22 patients), combined with side-to-side pancreaticojejunostomy to decompress an obstruction of the major pancreatic duct. In assessing the degree of terminal bile duct stenosis, calibration of the duct with Bakes dilators or rubber catheters was a useful aid. Two of the 22 patients ultimately proved to have carcinomas, producing obstruction of the pancreatic duct in the head of the gland. Both were treated initially with choledochoduodenostomy. This possibility must be considered in the management of these patients.
