[The extra-hepatic bile ducts. Apropos of a new case of abnormalities].

A double anomaly of extrahepatic biliary pathways was detected in the same patient. The first anomaly involved the cystic duct, which emptied into the third part of duodenum, the second anomaly the common bile duct which was implanted into the right side of the cystic duct one centimeter from the papilla. An anomaly of this type has not been reported previously in the literature and surgeons should be aware of its possible occurrence.
