Discrepancy Between Ultrasound and Oral Cholecystography in the Assessment of Gallstone Dissolution
Theodore F. Shapero, Irving E. Rosen, Stephanie R. Wilson, Murray M. Fisher – 1 September 1982 – 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.
