[Congenital dilatation of the common bile duct in which choledochal duct flows into Wirsung (author's transl)].

In a two year old girl, the authors observed a case of common bile duct dilatation, with jaundice and chronic pancreatitis, in which the common bile duct enters the Wirsung. An Y choledochojejunostomy was performed. The patient was easy recovered. As comment, the authors present a synthesis of knowledges of this malformation, very well studied in Japan, where it is less uncommon. We must try to find it by retrograd catheterism with duodenoscopic or surgical exploration. The systematic research of this low choledochal malformation must demonstrate if most part of congenital choledochal dilations were so explain as in japaneses publications or it is an autonomous illness and an etiology, among others, of congenital common bile duct dilatations.
