Fibrotic stricture of the extrapancreatic biliary tract: a new complication of acute pancreatitis. Two cases.

Two cases of fibrotic stricture of the extrapancreatic common bile duct were observed 3 and 5.5 months after severe acute alcoholic pancreatitis. The diagnosis was made by endoscopic retrograde cholangiography in both cases. Although colonic or ureteric stenosis have been reported after acute pancreatitis, this is the first report of extrapancreatic biliary stricture occurring after acute pancreatitis. The strictures could have arisen by either an enzymatic or ischemic mechanism. Outcome was favorable after surgical hepaticojejunostomy.
