ABSTRACT
The results of the treatment of 430 patients with benign tumors of the liver (BTL), including hemangiomas (41), nonparasitic solitary cysts (49), polycystosis (65) and parasitic hepatic lesions (alveococcosis-91, echinococcosis-184). To determine the character of a volume structure the accuracy of ultrasound and duplex sonography was tested (87.1-91.7%), as well as the accuracy of computer tomography (91.4-96.8%), angiography (90.6-96.3%), serological and radioimmunoassays. The use of these methods has increased the accuracy of diagnosis 2.2 times (in hemangiomas), nonparasitic cysts-to 1.2 times. The proposed methods of differential diagnosis and choosing of a proper treatment policy in patients with BTL made it possible to formulate indications and contraindications for the surgery, work out an optimal treating policy, depending on a character, location of BTL. The improvement of the surgical technique has decreased the rate of morbidity and mortality (2.5 and 1.5 times respectively).
