Abstract

A case of anomalous union of the pancreatico-biliary ductal system (AUPBDS) with a fusiform dilatation of the common bile duct, in which the arrangement of the two ductal systems was demonstrated with endoscopic ultrasonography (EUS), was reported. A 34-aged male was admitted for a surgical treatment with congenital dilatation of the bile duct. ERCP revealed AUPBDS of biliary joining type with a common channel of 13 mm in length. The constricted part of the common bile duct that seemed to join the main pancreatic duct within the pancreatic parenchyma was demonstarated by conventional ultrasonography. With EUS, the junction of the two ducts was much more clearly depicted and located in the pancreatic parenchyma. In conclusion, EUS seemed to be one of the most useful methods in imaging the extramural junction of pancreatic and biliary ducts in AUPBDS.
