[Technics for laparoscopic cholecystectomy--their use and results]. 
In mini-invasive surgery mainly two operative techniques for laparoscopic cholecystectomy are familiar and implemented in practice--"American" and "French" technique.  Over the period May 1993 to September 1997, in the two surgical clinics of H. M. I.--Pleven a total of 311 laparoscopic cholecystectomies are performed.  Of them 218 are done according to the "American" technique, 87--according to the "French" technique, and six patients are operated using the so-called "lifting" technique.  In the appear submitted the advantages and shortcomings of the two techniques for laparoscopic cholecystectomy are comparatively studied.  The timing of operative intervention CO2 quantity expenditure and intraoperative complications are analyzed.  The choice of technique for laparoscopic cholecystectomy depends on the surgeon's personal judgement, but under given situations one of the two techniques or a combination thereof should be mandatorily used.
