Background: Laparoscopic cholecystectomy (LCHE) is the method of choice for the treatment of symptomatic cholelithiasis and its complications. The authors set out to analýze outcomes of cholecystectomy over a one-year period, the conversion percentage, their reasons and early postoperative complications. Materiál and methods: 411 cholecystectomies were performed in the Department of Surgery at the 2nd Medical School, of Charles University and at The Central Military hospital in Prague within a one year period (2005), 296 of them by laparoscopic approach. Classic cholecystectomies was performed in 101 patients from a total number of 115 operations as a part of more extensive abdominal operations: during GIT operation, pancreas resection, liver resection, operations for benign and malign affections of extrahepatic bile duet, during operations for colorectal malignity, and operation for malign icteras with constraction of palliative biliodi-gestive anastomosis. 14 cholecystectomies were carried out classically for cholelithiasis and its inflammatory complications or upon suspicion of gallbladder tumour. Results: In 29 patients (9.8 % from 296 laparoscopic operations), conversion from laparoscopy to open operation was necessary. In one patient after conversion, early re-operation for subphrenic abscess and punction of right pleural exudates was needed. We noticed wound infection in 32 cases (10.8 %). Fluid at the site of paraumbilical video port installation oceurred in 18 patients (6.8%). Secondary wound healing at the other incisions oceurred in 17 patients (4.7 %), with co-incidence of fascia dehiscence in 2 cases (0.69 %). We identified biliáry leak in one čase (0.33 %), but this stopped spontaneously following prolonged drainage. We noted extended postoperative gut paresis (until the 5111 postoperative day) in 2 patients, this also spontaneously subsided. In our group of patients, we did not notě perioperative bile duet injury, and no patients died following the proceduře.
