[Problems inherent in the diagnosis and treatment of common bile duct calculi during video-laparoscopic cholecystectomy. Report on 700 cases, February 1991 to December 1997].

Conditions of predictivity seem to make treatment of common bile duct (CBD) stones during VLC more safe and adequate. IV cholangiography (or, nowadays, MRI and echoendoscopy) drive to a selective use of ERCP and cholangiography, help to reduce the incidence of residual lithiasis and give a "topographical map" of the CBD that can be useful, during VLC, in the search of the hilum structures, especially when the anatomical situation is not clear.
