title: Postcholecystectomy syndrome: evaluation using biliary scintigraphy and endoscopic retrograde cholangiopancreatography.
abstract: We prospectively studied 30 patients with postcholecystectomy syndrome to determine the efficacy of biliary scintigraphy in the detection of stenosis of the sphincter of Oddi. All patients underwent endoscopic retrograde cholangiopancreatography (ERCP). Biliary scintigraphy disclosed stenosis of the sphincter by agreement with the ERCP or surgical findings in nine (90%) of ten patients and in eight (100%) of eight patients with biliary obstruction from other causes. Retention of activity at 2 hours in visually prominent ducts was the best predictor of abnormal biliary drainage. Biliary scintigraphy is a useful, noninvasive screening test for the detection of postcholecystectomy biliary obstruction.
