title: Sensitivity of ultrasonography in the demonstration of common bile duct stones and its ranking in comparison with intravenous cholangiography and endoscopic retrograde cholangiopancreatography.
abstract: A series of 75 patients with surgically verified common bile duct (CBD) stones were re-examined in retrospect, in order to ascertain the sensitivity of ultrasonography (US) in the detection of CBD. The sensitivity of US turned out to be 19%. US detected bile duct dilatation in 58% and all the CBD stones detected or suspected were seen in cases with bile duct dilatation. The sensitivity of intravenous cholangiography (IVC) proved to be 24%. Endoscopic retrograde cholangiopancreatography (ERCP), however, was found to be by far the most sensitive method, since it demonstrated 84% of the CBD stones.
