  • Title: Scintigraphic evaluation of bile dynamics before and after endoscopic sphincterotomy.
    Author: Chandramouli B, Gupta SM, Cohen GE.
    Journal: Clin Nucl Med; 1994 Sep; 19(9):800-2. PubMed ID: 7982316.
    Abstract:
    Endoscopic sphincterotomy has been used for the treatment of many biliary disorders, including extraction of obstructing common bile duct stones. Manometric studies of the sphincter of Oddi and the common bile duct have shown a marked decrease in biliary tract pressures after sphincterotomy. A prospective study of 12 patients with intact gallbladders using hepatobiliary imaging before and after sphincterotomy was performed to assess changes in bile dynamics. Nonfilling of the gallbladder occurred in 9 of the 12 patients after sphincterotomy, indicating significant alteration of bile flow. Such changes in bile dynamics may have serious implications in patients selected for medical dissolution of gallstones. It may also adversely affect specificity of cholescintigraphy in diagnosing acute cholecystitis.
