Abstract:
In 101 jaundiced patients, gray scale ultrasonography of longitudinal scan in RAO position demonstrated themeasurable extrahepatic biliary system in 73 patient; 17 cases (50%) of those with nonobstructive jaundice and 56cases (84%) of those with obstructive jaundice. The size of the internal diameter of extrahepatic biliary systemindicated that obstructive jaundice was best differentiated from non-obstructive jaundice when diameter above 7mm served as abnormal extrahepatic duct in jaundiced patients, giving sensitivity 85.5% specificity 97% anddiagnostic accuracy 89.5% by decision matrix analysis. The overall etiological diagnostic accuracy in obstructivejaundice was 40% which had higher one in choledocholithiasis and pancreas head carcinoma than other diseases. Thesonography should be imaging procedure of choice in differential diagnosis of jaundiced patients, which is simple, safe, noninvasive and has high diagnostic accuracy in differentiation between the two.
