Abstract
The Sunnybrook Medical Centre Gallstone Study is a randomized, controlled, double–blind study of chenodeoxycholic acid for dissolution of radiolucent gallstones. Of the first 22 patients whosestones were apparently totally dissolved on oral cholecystography, seven were found to have residual small stone fragments on ultrasound examination of the gallbladder. Continuing chenotherapy was unsuccessful in dissolving these fragments. The possibility that the residual stones represent insoluble nuclei of the original calculi must be considered. Responses to cholelitholytic therapy and subsequent stone recurrences need to be reevaluated using ultrasound.Keywords
