 Sixty cases of the congenital dilatation of the bile duct including 48cases with various abnormal pancreatico-cholangio connections were roentgenologically studied and discussed about their diagnostic procedures.

 Eight types (A-H) were classified according to the location of the dilated bile duct. The majority (87%) of the cases showed the type A and B which were accompanied with the abnormal pancreatico-cholangio connection in all cases. But, in the other cases, abnormal pancreatico-cholangio connection were not detected.

 There were such complications as pancreatitis and malignancy of the bile duct in some cases and it was pathogenetically and diagnostically important that the complication of malignancy was only observed in the cases showing type of A and B. Therefore, for the precise detection of the congenital dilatation of the bile duct, not only the demonstration of the entire biliary tract but also the existence of the abnormal pancreatico-cholangio connection should be investigated. First of all, non-invasive examinations such as ultrasound, drip infusion cholangiography and hypotonic duodenography are to be performed, but ERCP should also be done by all means to obtain the analysis of pancreatico-cholangio connection.
