• A choledochal cyst in the adult patient is not just an aneurysmal dilatation of the common bile duct, but it is the most obvious manifestation of a more widespread pancreaticobiliary ductal dysplasia. Most patients have abnormalities of the pancreatic ducts and, frequently, multiple areas of dilatation involving the intrahepatic bile ducts. Of our nine patients, six had pancreatograms, five of which were distinctly abnormal. Two of the five had recurrent pancreatitis. Six patients were found to have marked stenosis of the outflow tract from the cyst. Because the mucosa lining the choledochal cyst was chronically ulcerated, anastomoses to the cyst formed strictures in seven (64%) of 11 patients, and the long-term risk of carcinoma arising in the cyst was increased. The preferred therapy was excision of the cyst with Roux-en-Y hepaticojejunostomy.
