One hundred and twenty-three patients from a hyperendemic focus underwent ultrasound study. The anteroposterior size of the liver, the thickness of the wall of the gallbladder and the nature of its contents, the diameter of common bile ducts and portal vein, additional morphological changes in the architectonics of the liver and biliary ducts were determined. Examinations have established that ultrasound study is a technique determining the characteristic signs that are pathognomic to moderate and severe invasions--cholangiectases (predominant localization in the second segment of the liver), a significant increase in the anterioposterior size of the liver and an change in the parenchyma of the organ, the thickening of the wall of the gallbladder, an change in its content (at the expense of sediments, flocculi, waxes, and concretions), and an increase in the size of the intrahepatic and common bile ducts.
