title: Laparoscopic cholecystectomy: its impact on national health economics.
abstract: OBJECTIVE
  To assess whether sound economic reasons exist for the wider introduction of laparoscopic cholecystectomy in Australia.
  
  
  METHODS
  A retrospective survey of patients who underwent laparoscopic cholecystectomy. We compared time of hospital stay and time off work after laparoscopic cholecystectomy with data for open cholecystectomy.
  
  
  METHODS
  Seventeen participating surgeons in four Australian States allowed access to patients treated between May 1990 and November 1991 (1254 patients in all).
  
  
  METHODS
  Patient acceptability of the procedure, average length of postoperative in-hospital stay, and the savings associated with earlier return to work compared with open cholecystectomy.
  
  
  RESULTS
  Almost 90% of patients (1127) replied and 1088 responses were considered appropriate for analysis. Serious complications were rare; 96% of patients thought the technique was successful. The mean length of in-hospital stay was 2.6 days (range, 1-120), compared with a mean of 8.7 days for open cholecystectomy. Among working patients, the mean time to return to work was 11.6 days (range, 10.7-13.1), an estimated 27 days sooner than after open cholecystectomy. Extrapolating from these results, replacing 95% of open cholecystectomies with laparoscopic procedures would have 133,285 hospital bed-days and 500,000 work-days each year.
  
  
  CONCLUSIONS
  Laparoscopic cholecystectomy is safe and effective. Its wider use in Australia would result in savings to both the individual and the national economy.
