[Gallbladder and common bile duct calculi: treatment with laparoscopy vs laparotomy. Costs and benefits].

The cost-benefit ratio of laparoscopy vs laparotomy was evaluated comparing 2 groups of patients: 500 operated using traditional laparotomy and 500 operated via laparoscopy. The first parameter considered was the average hospital stay, which was 8.4 days (min. 3, max. 22 days) in group I (laparotomy) (Fig. 1) against 4 days (min. 2, max. 13 days) in group II (laparoscopy). Even more interesting were the results related to the average postoperative hospital stay: 5 days for laparotomy, 2 days for laparoscopy. Currently, 90% of patients submitted to laparoscopic cholecystectomy is discharged in the first postoperative day. The cost of the surgical procedure is 1,100,000 It. Lit. for laparotomic cholecystectomy and 2,130,000 It. Lit. for laparoscopic cholecystectomy. However, considering the cost of the daily hospital stay and adding the cost of the surgical procedure we already save 50% with the laparoscopic method. Furthermore, if we consider the time occurring between patients' discharge and return to work a 50% reduction of the postoperative recovery time is obtained. The conclusions of the Authors are the following: Laparoscopic cholecystectomy performed by skilled surgeons presents an incidence of complications comparable to traditional cholecystectomy. The operating time is almost the same for both methods. Operative costs are higher for the laparoscopic technique. Postoperative hospital stay is drastically reduced with the laparoscopic procedure. Return to work is assured in a shorter time after laparoscopy.
