Incidence of stenotic lesion of the biliary tract in malignant group was more higher than that in benign group, 41cases were malignant stenosis and 13 cases were benign. Jaundice was significantly seen in the cases with malignant stenosis but fever and epigastralgia were significantly seen in benign cases, respectively. Then, serum total bilirubin level in malignant stenosis was more higher than that in benign one. Stenotic lesion of the biliary tract often recognized on the upper bile duct. The form of the stenotic lesion of the cholangiogram classified four types; among them tightening type and growing one were frequently found. Smooth edge of the bile duct in cholangiogram was significantly more frequenthy seen in benign stenosis but irregular edge was significantly seen in malignant cases. Sclerosing findings of the bile duct were frequently found in malignant stenosis. Eleven patients that showed stenotic lesion more than 30mm in length and 6 patients that showed dilatation of bile duct more than 20mm in diameter were all malignant stenosis.}, pages = {250--257}, title = {胆道狭窄病変に関する臨床的研究}, volume = {101}, year = {1987} }
