Abstract

Choledochocele is a rare abnormality that's defined as cystic or diverticular dilatation of the common bile duct, and this protrudes into the duodenal lumen. It may cause abdominal pain, recurrent pancreatitis, obstructive jaundice etc. Although its anatomic form does not meet the criteria of pancreaticobiliary malunion, malignant changes of the choledochocele in relation to pancreaticobiliary reflux may occur. It still is regarded as having a lower malignant potential than any other type of choledochal cyst. Only one case has been currently been reported in Korea. We experienced a case of a 71 year-old woman with upper abdominal pain that was caused by a choledochocele with duodenal ampullary adenocarcinoma. She was successfully treated by surgical excison without severe complications. We report here on this case along with a review of the literature.
