    Annual meeting of the International Society for Technology Assessment in Health Care. Barcelona, ESP, 1997.


    The least costly management strategy for patients undergoing laparoscopic cholecystectomy is unclear.


    A decision model incorporating cost ratios, test accuracy, complication, and failure rates was used to determine the costs of 4 peri-laparoscopic cholecystectomy strategies : endoscopic retrograde cholangiopancreatography (ERCP), intraoperative cholangiography (IOCG), endoscopic ultrasound (EUS), and expectant management.


    Expert IOCG is least costly for intermediate-risk patients when the risk of stones is between 17% and 34%. If expert EUS is available, 0% to 10% ( « low » risk) merits expectant management ; 11% to 55% ( « intermediate » risk) merits EUS ; and greater than 55% ( « high » risk) merits ERCP.

    Thresholds were most sensitive to changes in the risks of symptoms and complications due to retained stones ; and to procedural costs, sensitivity, and success rates.

    Neither IOCG nor EUS appears likely to reduce overall costs unless their accuracy and success rates are greater than 90% and their procedural cost is less than 60% to 70% that of ERCP.

    When neither are available, ERCP is preferable when the risk of stones is greater than 22%. Thresholds were relatively insensitive to changes in the risk and severity of ERCP-induced pancreatitis. (...)
