[Liver in children with prior intrathoracic tuberculosis during long-term observation period after chemotherapy].

Ultrasonography of the liver and biliary tract revealed both nonspecific (chronic persistent hepatitis) and paraspecific changes in 93.8% of children with local forms of primary tuberculosis in the phase of infiltration, including 17.3% in whom the changes appeared as biliary dyskinesia. Late outcomes indicated that antituberculous chemotherapy had no negative effect on the liver. The ultrasonographic studies detected abnormal changes of the hepatic parenchyma only in 7.8%, mainly in those with chronic persistent hepatitis.
