The authors evaluated the diagnostic accuracy of ultra sonography in the differential diagnosis of jaundice in 63 cases who were confirmed byoperation and other diagnostic methods from Jan. to Aug 1982 at the department of internal rnedicine in Busan National University Hospital. Of 63 cases of jaundice, on ultrasonographic examination biliary obstruction was 36, and non-obstruction of bile duct was 27 according to the degree of bile duct dilatation(common bile duct 6mm, intrahepatic bile duct>4 mm). The sensitivity of ultrasonography in the diagnosis of biliary obstruction was 92% and specificity was 92,%, therefore overall accuracy of ultrasonography in the differential diagnosis of jaundice was 92%. In the detection of the exact caseses of jaundice the diagnostic accuracy of ultrasonography was 54% in obstructive jaundice, 38% in non-obstructive jaundice. So ultrasonographic examination appears to be a simple, reproducible, and high accurable screening method in the differentical diagnesis of jaundice although relatively low valuable in the diagnosis of exact causes of jaundice.
