Treatment of congenital dilatation of the choledochus- reconstruction of the bile duct after resection of the dilated choledochus.

Reconstruction of the way of bile flow was attempted in 21 cases with the resection of the dilated bile duct, and the post-operative courses were observed over a long period. It was found that ascending cholangitis is seldom caused by the hepaticoduodenostomy. It is important, when hepaticoduodenostomy is performed, that the sound section of the wall of the bile duct without stenosis in the hepatic side should be selected. Reconstruction of the way of the bile flow to prevent ascending cholangitis by leading normal bile flow into the duodenum should be devised.
