Comparison of laparoscopic cholecystectomy with open cholecystectomy in a single center

In this retrospective study, we compared the results of 1,283 open cholecystectomies (OCs) performed at our medical center during the pre-laparoscopic era with 1,107 laparoscopic cholecystectomies (LCs) performed from 1990 to 1992.

The percent -age of patients undergoing intraoperative cholangi -ography was similar for patients with chronic chole -cystiris for each period, although the incidence of abnormal cholangiograms was lower in the laparo -scopic era (5.8% versus 15.2%, p
