[Reoperations on the extrahepatic bile ducts after surgery of the common bile duct or its indirect drainage].

An analysis is made of 80 re-interventions on the extra-hepatic biliary pathways in patients who had underwent one or more surgical interventions on the main biliary pathway. The cases have been classified according to the type of the initial intervention as follows: re-interventions following cholecystectomy, choledocotomy and Kehr drainage, following sphincterotomy, and following internal and external biliary derivations. An analysis is made of the causes of re-interventions, and of the increased risk due to severe complications which are at the origin of high morbidity and mortality rates. Particular stress is laid on the necessity for a correct diagnosis, as well as a complete one for the first intervention on the biliary pathways, which will allow to make an adequate choice for a second surgical solution.
