[A new technique in positioning of Kehr's tube in laparoscopy].

The enlargement of the indications in the use of the laparoscopic technique puts the surgeon in front of the need to project new techniques and to improve new instruments daily. On one hand, the technique and instruments used to perform a video-laparoscopic cholecystectomy are codified. However, there is still a lot of work to do for the laparoscopic treatment of the common bile duct stones. The aim of the present scientific contribution is the exposition of an original methodology for the positioning of the T-tube in laparoscopy which would be a difficult manoeuvre otherwise.
