The results of 1122 laparoscopic cholecystectomies have been analyzed which were performed within a two year period of time. In 1097 (97.8%) cases the authors managed to carry out the laparoscopic procedure, however in 25 patients (2.2%) the operation had to be converted to an open surgery. There was no hospital mortality, however 1 patient died at home due to pulmonary embolism. (Mortality: 0.09%) According to their survey 758 patients exhibited concurrent medical risk factors and 413 previous abdominal operations increased the "surgical" risk of laparoscopic procedures. 27 early and 46 late postoperative complications have been observed. In 3 instances (0.26%) bile duct injury occurred and in 5 cases (0.44%) reoperations had to be carried out secondary to postoperative complications. Forty patients (3.6%) have had recognized common bile duct stones, these were removed, in part preoperatively (28pts), in part postoperatively (11pts) by endoscopic sphincterotomy (EST). In one case a laparoscopic retrieval of common bile duct stone was accomplished via the dilated cystic duct. 47% of their patients left the hospital on the first day and 78% of them were discharged within 2 days.
