  • Title: A computer model for evaluating the costs of cholecystectomy or ursodiol treatment in the management of cholelithiasis.
    Author: Crain K.
    Journal: Clin Ther; 1990; 12(3):250-62. PubMed ID: 2379230.
    Abstract:
    Over 500,000 cholecystectomies are performed each year in the United States. The procedure has its risks (mortality is 1.2% in the general population and 3% in patients aged 75 years or over) and it is expensive: the average direct cost of each cholecystectomy is about $10,000, for a national total of $5 billion annually. An alternative to surgery is to dissolve the stone with ursodiol, a naturally occurring bile acid, which has been successfully used for cholesterol gallstones with a diameter less than 20 mm. A computer model was developed to compare the costs of surgery for gallstones and treatment with ursodiol. In a hypothetical health maintenance organization with one million enrollees, use of ursodiol treatment rather than cholecystectomy would result in cumulative savings of $8.5 million after one year, $30.7 million after five years, and $57.8 million after ten years.
