EVALUATION OF THE COST OF LAPAROSCOPIC AND OPEN CHOLECYSTECTOMY

Despite the rapid growth of laparoscopic cholecystectomy, the comparative costs of this new procedure and open cholecystectomy remain unknown. In this study the costs have been evaluated of a consecutive series of patients undergoing these procedures in a district general hospital with an established resource management centre. Fifty consecutive patients undergoing open cholecystectomy between June 1988 and July 1990 immediately before the introduction of laparoscopic cholecystectomy and 100 patients undergoing laparoscopic cholecystectomy between August 1990 and June 1992 were studied. Costs estimated prospectively for each patient were compared. The mean cost per patient of open cholecystectomy was estimated at pound 2102 compared with pound 2026 for the first 50 patients undergoing the laparoscopic procedure. The mean cost pound 1744) for the second 50 patients undergoing laparoscopic cholecystectomy was less than that for either open cholecystectomy (P < 0.005) or the initial 50 laparoscopic operations (P < 0.03). Operating theatre costs and equipment costs were higher in both laparoscopic groups. These were offset by the higher nursing and ward costs of open cholecystectomy. For the laparoscopic procedure the operating theatre times and duration of hospital stay were both less in the second 50 patients than in the first 50. After the initial learning period, laparoscopic cholecystectomy is less expensive than the open operation and represents a cost-effective method for treatment of the patient with gallstones.
