A retrospective study was carried out on 66 patients (44 female, 22 male), mean age: 55.8 (31-87 years old) who were undergone laparoscopic cholecytectomy (LC) for acute calculus cholecystitis. Among them, 22 patients (33.3%) had one or more associated internal diseases. 12 patients (18.2%) had gangrenous cholecystitis. LC was successful in 61 patients (92.4%), other 5 patients (7.6) were transferred to open procedure. In 55 patients (83.3%), LC was performed with 3-trocar technique. The mean operative time was 108 ± 41 minutes (from 40 to 295 minutes). The mean hospital stay was 4 ± 1.8 days (range 2 to 11 days). Complications occurred in 10.6% of patients. There was no intraoperative bile duct injury and there was no death in this study
