The characteristic pathophysiology of both cystic and fusiform types in congenital biliary dilatation were studied using 51 cases experienced in our department and the following results were obtained. 1. Sex incidence of female was more frequent in cystic type. 2. Bile flow disturbance was observed more frequently in cystic type. 3. Chyledocal walls were more thick in cystic type. 4. Mucous glands of choledocal wall were prominently seen in cystic type. From these results, the characteristic etiology was not easily determined and the quolitative differences of several factors, such as above factors, may play an important role in making form of either cystic or fusiform type.
