[Radionuclide and sonographic diagnosis of lesions of the hepatobiliary system in opisthorchiasis].

Radionuclide and sonographic studies of liver and biliary tract of 37 patients infested with O. felineus, including 7 patients with an early and 30 with late chronic disease were performed. Alterations in radionuclide and sonographic characteristics were revealed, pointing to dyskinetic disturbances in the gallbladder and to the cholestatic syndrome (reduced secretory function of the liver, dilated bile ducts, late visualization and reduced concentration function of the gallbladder). The most profound abnormalities in the indices were seen in patients early in the disease. Prasiquantel treatment contributed to rapid restoration of gallbladder motor function.
