[A prospective and comparative study of 262 laparoscopic cholecystectomies]

A prospective, comparative study is made of 262 patients (195 males, 67 females) subjected to laparoscopic cholecystectomy. Two groups were considered: simple cholelithiasis (SC) (187 cases), and complicated cholelithiasis (CC) (75 cases: 63 acute cholecystitis, 8 hydrocholecystitis, 4 pancreatitis). Mean age was 51 among the SC cases, and 57 in the CC patients. Mean operating time was 67 and 96 minutes for the SC and groups, respectively. Preoperative complications were more frequent in the CC group (51.4%) than in the SC patients (24%)--immediate laparotomies being performed in 2 and 25% of the SC and CC patients, respectively. Mortality was zero, with similar morbidity in both groups. Mean hospitalization time was 4.9 and 3.4 days for the CC and SC groups, respectively.
