Laparoscopic cholecystectomy (LCH) is a surgical method which is minimally invasive thus enjoying an increasing popularity among both patients among the patients surgeons. Conversion of laparoscopic cholecystectomy is comprehended as a retrieve to the classical surgical method based on laparotomy in any phase of operation. The study deals with reasons for conversion of the initial one hundred LCH which were performed by 7 surgeons at the Department of Surgery in Ruzinov Hospital in Bratislava during the period from 27.11.1992 to 31.3.1994. Out of one hundred cases, 5 LCH required conversion to open laparotomy--5%. The most frequent rate of conversion is from 3 to 8%. Reasons for conversion in our patients include. Impossibility to introduce safety the trocar with the video camera (1x), unclear anatomic situation (1x), bleeding from the cystic artery (1x), perforation of the gallbladder and subsequent leakage of bile and stones in to the peritoneal cavity (1x), technical failure (1x). We cannot comprehend the conversion of LCH as a failure of the operating surgeon. It insinuates that the surgeon is careful and responsible for his patient. It is a sign of his good surgical judgement.
