A Case of Choledochocele with Parapapillary Diverticulum Presenting as Pancreatitis / 대한소화기내시경학회지

ABSTRACT

Choledochocele, classified as choledochal cyst type III, is a rare cystic or diverticular dilatation of the terminal biliary tree that causes abdominal pain, recurrent pancreatitis, and obstructive jaundice. It is the rarest of the choledochal cysts and has lower malignant potential than any other type of choledochal cyst. Although its anatomic structure does not fit the criteria for pancreatobiliary maljunction, pancreaticobiliary reflux may occur in patients with choledochocele. Herein, we report the case of a 63-year-old woman with recurrent episodes of acute pancreatitis that were caused by a choledochocele with two parapapillary diverticula. She was successfully treated by endoscopic needle-knife sphincterotomy without severe complications and remained asymptomatic at the 6-month follow-up.
