Alternative (nonresective) therapies of symptomatic cholelithiasis have been followed by frequent recurrence of gallstones. Great interest has been generated by the recent development of laparoscopic cholecystectomy, which in addition to preventing recurrence, may be associated with less patient discomfort, shorter hospital stays and more rapid return to work than standard cholecystectomy. We compared the first 25 patients who underwent laparoscopic cholecystectomy at our institution to the most recent 25 patients undergoing standard cholecystectomy by the same surgeon. The results of analysis of the two patient groups showed that they were similar in age, weight and gallstone burden. A slightly longer operative time (mean plus or minus S.E.M., 122 +/- 9 minutes versus 95 +/- 5 minutes, p) was required to perform laparoscopic cholecystectomy than standard cholecystectomy during this early experience. However, patients undergoing laparoscopic cholecystectomy had a markedly diminished usage of parental narcotic analgesia during the first 24 hours postoperatively (1.7 +/- 0.5 milligrams of morphine sulfate versus 34.5 +/- 4.1 milligrams of morphine sulfate). They also were discharged from the hospital (1.0 +/- 0 days versus 4.1 +/- 0.3 days) and returned to work or unrestricted activity (8.5 +/- 1.1 days versus 35.6 +/- 4.5 days) much sooner postoperatively than those treated by standard open cholecystectomy. Based on these favorable results, we conclude that laparoscopic cholecystectomy should be the procedure of choice for most patients with symptomatic cholelithiasis.
