Abstract

Anomalous union of pancraeticobiliary drain (AUPBD) is uncommon anomaly of the pancreaticobiliary ductal union system. Usually, this anomaly is confirmed by long common channel (>15 mm) at ERCP and is divided into according to relationship between pancreatic duct and common bile duct. Recently several reports showed that AUPBD may be associated with congenital choledochal cyst and gallbladder carcinoma. A 33-year old man was admitted with RUQ pain and jaundice. Ultrasonography, Abdominal CT, ERCP, and PTBD cholangiography showed type I choledochal cyst, AUPBD and focal adenomyomatosis on the gallbladder. Whipple's operation with excision of the choledochal cyst and chloecystectomy were performed for treatment. This clinical experience suggests that high incidence of choledochal cyst in patients with AUPBD and gallbladder adenomyomatosis are may be closely related to the carcinogenesis of gallbladder cancer in patients with AUPBD.
