Laparoscopic versus open cholecystectomy: a prospective comparative study in the elderly with acute cholecystitis.

The aim of this prospective comparative study was to determine the feasibility and the efficacy of laparoscopic cholecystectomy for acute cholecystitis in patients older than 75 years of age and to compare the results with those of open cholecystectomy. From January 1992 to December 1999, 139 patients older than 75 years of age underwent cholecystectomy for acute cholecystitis. The two groups of patients with cholecystolithiasis included 50 patients who underwent laparoscopic cholecystectomy (group 1) and 89 patients who underwent open cholecystectomy (group 2). Group 1 consisted of 30 women and 20 men, with a mean age of 81.9 years (range, 75-98). Group 2 consisted of 51 women and 38 men, with a mean age of 81.9 years (range, 75-93). There was no difference in the American Society of Anesthesiologists classification in both groups. The length of the surgery (103.3 vs. 149.7 minutes), postoperative length of stay (7.7 vs. 12.7 days), and inpatient rehabilitation (15 vs. 42 patients) were significantly shorter in group 1 than in group 2. The postoperative morbidity rate was not different between the groups. There was no mortality in group 1, but four patients died in group 2 (P = 0.29). The conversion rate was 32% (n = 16) in group 1. In summary, laparoscopic cholecystectomy in elderly patients with acute cholecystitis is safe and effective. Laparoscopic cholecystectomy in elderly patients restores them to the best possible quality of life with the lowest cost to them physiologically.
