Anomalous union of the pancreaticobiliary duct (AUPBD) is a rare congenital anomaly, defined as the pancreaticobiliary ductal union located outside of the duodenal wall, usually forming a markedly long common channel. This anomaly is associated with congenital choledochal cyst, carcinoma of the biliary tract and pancreatitis, and is more commonly seen in Asian than in Western countries. AUPBD is frequently accompanied by biliary dilatation, but some patients with AUPBD have no biliary dilatation. The causal relationship between AUPBD and biliary dilatation associated with this anomaly has not been fully established. Here, we report a case of type IIIc2 AUPBD without biliary duct dilatation that was treated by drainage of major papilla.
