[Laparoscopic cholecystectomy. Our experience]

This study analysed 90 cases of symptomatic cholelithiasis treated with laparoscopic cholecystectomy. 27% of the cases studied suffered from microlithiasis, 44% from multiple calculosis with calculi measuring 1 to 2 cm in diameter, 25% from single calculi measuring up to 4 cm in diameter, and 4% from a benign proliferative pathology of the cholecystic wall. Calculosis of the main biliary tract was also found in 3 patients and was treated by preoperative endoscopic papillosphincterotomy. In addition to routine tests and ultrasonography, endovenous cholangiography, or retrograde cholangiography (ERCP) in cases of suspected calculosis of the biliary tract, was always performed prior to surgery. Mean operating time was 60 min. Two procedures were converted into laparotomy due to laceration of the cystic artery. In one case laparotomy was performed on day two due to choleperitoneum following a lesion of the cystic duct. Pneumoperitoneum could not be performed in three cases. Mean hospital stay was 48 hours. No other intra- or postoperative complications were reported. These results support the opinion that laparoscopic cholecystectomy is a safe method, with few limitations and represents the treatment of choice in the therapy of symptomatic cholelithiasis.
