[Intraoperative cholangiography in laparoscopic cholecystectomy. Our experience]

Cholangiography during conventional cholecystectomy has always been useful for anatomo-topographic study and for research of the stones of biliary tree. After a natural period of training the authors included the easy technique of cholangiography in laparoscopic cholecystectomy. The study was performed in 13 patients using Olsen's cannula with an internal a normal catheter for cholangiography. The catheterization of the cystic duct was performed in 85% of cases (11 patients), in the other 15% (2 patients) it was not possible to cannulate the cystic duct. Non complication. The mean duration of the study was 14 minutes. The authors describe the technique and conclude, after a brief discussion of the reports in the literature and personal experience, that peroperative cholangiography is an easy and safe procedure without risk and prevents the injuries to the biliary tract whose incidence is about 1.3%.
