title: Intravenous computed tomographic cholangiography in acute cholecystitis. A comparison with conventional cholangiography.
abstract: Forty-nine patients with clinical signs of acute cholecystitis underwent conventional and computed tomographic cholangiography. Among 39 patients with signs of contrast medium in the biliary system at both examinations there was a diagnostic discrepancy in only one patient. Conventional radiography demonstrated cholecystopathy in this patient while contrast medium in the gallbladder and an acute pancreatitis were found at computed tomography. Ten patients with an indeterminate conventional cholangiography had a conclusive computed tomographic examination. Twenty of 30 patients with an abnormal computed tomographic cholangiography underwent cholecystectomy and all had diseased gallbladders. All 17 patients with histopathologically confirmed acute cholecystitis had signs of subserosal edema and/or changes in the omental fatty tissue adjacent to the gallbladder at computed tomography. A layer of tissue of water-density adjacent to the gallbladder and/or changes in omental fatty tissue were also seen in one patient with congestive heart failure and in one with a penetrating duodenal ulcer. None of the 19 patients with a normal computed tomographic cholangiography had a proven acute cholecystitis.
