[Intraoperative ultrasonic study in surgery of hepatic echinococcosis].

The authors analyse the results of intraoperative ultrasonic examination (IOUSE) of the liver in 31 patients with echinococcosis of the liver; 21 of them had multiple hydatid cysts in the liver. The authors came to the conclusion that IOUSE is a highly informative method for noninvasive diagnosis in surgery of the liver. IOUSE is indicated when information must be obtained during the operation concerning the location of invisible and nonpalpable pathological structures, the borderlines of their extension, the anatomical relations with the vascular-ductal structures of the liver. Exact echographic localization of these structures and their grading ensure safety of various types of operations in this disease.
