ERCP Findings In Hepatic Clonorchiasis / 대한소화기내시경학회지

ABSTRACT

An endoscopic retrograde cholangiographic study of 25 consecutive cases of hepatic clonorchiasis was performed during the period from Aug. 1986 to Sep. 1991 Hepatic clonorchiasis was confirmed by stool of examination for Clonorchis sinensis. The findings consist of characteristic filling defects and changes in the intrahepatic and extrahepatic bile ducts. The filling defects due to adult worms are significant diagnostic criteria of clonorchiasis. Its appearance is elliptical and/or round. The change in the intrahepatic bile ducts consisits of dilatation, irregularity(tortousity and elongation) and blunting of termieal branches of bile tree, irregular stenosis, fuzziness and raggedness. The characteristic changes in the extrahepatic bile ducts in clonorchiasis are duct wall irregularities and mild dilatation of bile duct. ERCP is an excellent method to evaluate biliary tree in patient with clonorchiasis because it reveals not only its characteristic findings of clonorchiasis but also its severity and associated lesions.
