[Cholecystectomy by laparoscopic approach. A trial for evaluating the biliary risk].

Owing to the wide diffusion of the coelioscopic cholecystectomy some problems are worth studying. From a technical standpoint they are important changes: use of monopolar current for coagulation, suppression of intra-operative cholangiography, absence of suture of the gallbladder bed, systematic retrograde dissection. Theoritically these modifications are important enough to increase the biliary risk. As a matter of fact, comparison with traditional cholecystectomy data as well as results of preliminary studies on coelioscopic cholecystectomy does not confirm such a risk. This operation appears safe, at least if indications are limited to non complicated cholelithiasis.
