[The ultrasonic diagnosis of lesions of the hepatobiliary system in protracted forms of viral hepatitis in children].

Ultrasound examination of the hepatobiliary system was carried out in 102 children (3-12 years) with viral hepatitis A and B on the 57-75 days of the disease. Increased liver size and swelling of the parenchyma was revealed in 100% of patients. Thickening of the gallbladder walls was similarly frequent in A and B hepatitis. In 40% deformation of the gallbladder was revealed in 40.1%. The pancreas was increased in 13.6%, indurated in 36.4% of patients. Changes in the gallbladder and cholangitis are clearly related to the level of bilirubinemia ALT activity that is one of the causes of delayed convalescence.
