[Extrahepatic biliary tract atresia and a common biliopancreatic canal. Review of the literature apropos of a case].

The authors report the case of an 3 months old caucasian boy which had an extrahepatic biliary atresia associate with a congenital biliary cyst and an anomalous pancreaticobiliary junction. The patency between gallbladder and duodenum permits the operative opacification of this long common pancreaticobiliary channel. The congenital biliary cyst was located on the upper part of the common bile duct and was obstructed by biliary concretions. Unfortunately, no patency between intrahepatic bile ducts and this cyst was found. Because this long common pancreaticobiliary channel may cause biliary dilatation or biliary cancer, we performed an hepatic portoenterostomy rather an hepatic portocholecystostomy. A few weeks later, the bile flow was restored and the jaundice decreased. With a follow up of 18 months, this boy is currently anicteric, despite the hepatic fibrosis found on the operative biopsy. The association extrahepatic biliary atresia-long common pancreaticobiliary channel is uncommon and only 20 cases were reported. In our case, the pancreatic juice reflux into the biliary tract might have caused the dilatation of the common bile duct and the biliary atresia by chronic obstructive cholangiopathy.
