ASYMPTOMATIC EXTRAHEPATIC PORTAL OBSTRUCTION WITHOUT PORTAL HYPERTENSIVE FINDINGS DETECTED IN ULTRASONIC MASS-SCREENING

Background/Aims: We report three adult cases of extrahepatic portal ob struction (EHPO) detected by ultrasonic (US) mass screening. Material and Methods: All these cases were asymptomatic with no abnormalities o n hematological or biochemical tests, Only indocynanine green clearanc e test revealed a slight abnormality. By imaging modalities, the porta l trunk could not be visualized and cavernous transformation could be visualized. Results: There were no findings of portal hypertension, su ch as splenomegaly, esophageal varices and hepatofugal collaterals, in any of these cases. Conclusions:As many EHPOs without symptoms can be detected on US mass survey, US is considered to be the best modality for screening for this disease.
