[Analysis of failures in laparoscopic cholecystectomy]

The aim of the study was an analysis of the causes of conversion from LCh to the traditional operation in the large group of unselected patients. 1991 in 31 LCh-2 cases were converted (5.8%), in 1993 in 862-11 cases (1.3%). In the remaining years the frequency of conversion was below 1%. Altogether in 4000 LCh conversion was necessary in 44 cases. Causes of the conversion: in 23 patients lack of possibility to visualize the gallbladder neck, in 12 cases acute inflammation of gallbladder, in 11 cases chronic inflammation, in another 6 patients laparotomy was performed because of gallbladder carcinoma, in 4 cases because of gallbladder fistulation. The most common cause of conversion were adhesions of the neck of a gallbladder. Conversion rate can be lowered to below 1%.
