A retrospective analysis of 6,387 cholecystectomies

This is the largest retrospective analysis of biliary tract surgery ever reported involving 6,378 patients operated on during a three year period, 1990-1992. During this time interval, the frequency of laparoscopic procedures has increased dramatically. The use of laparoscopic procedures was associated with a significant decrease in the total length of hospital stay and total charges as compared to the open procedures. Because of laparoscopic surgery's increased acceptance, we propose that the frequency of laparoscopic surgery of the biliary tract should be used as a quality control measure.
