[Dissection of the Calot's triangle by the celioscopic approach]. / Dissection du triangle de Calot par voie coelioscopique.

ABSTRACT

Laparoscopy seems to increase the frequency of post-cholecystectomy biliary complications. Irrespective of the instruments and techniques utilized, dissection of Calot's triangle must be performed in compliance with the classical rules of bile duct surgery. These rules are always keep in contact with the gallbladder; completely dissect the Calot's triangle area which must not contain more than one biliary tract element; never dissect the cystic duct beyond the right border of the hepatic choledochus; never section an element that is not identified with certainty; systematically perform a peroperative transcystic cholangiography, in particular to detect the anatomical variants of the extra-hepatic biliary ducts.
