[Computed tomography diagnosis of hepatic space-occupying lesion of different nature].

Specific CT-symptoms are reliable criteria for differential diagnosis of benign lesions of the liver. The method permits to diagnose exactly cystic lesions of the liver in 95.3% cases, and tumor lesions -- in 83%.

[An algorithm for differential diagnosis searching in space-occupying lesions of the liver].

The experience of examination of 584 patients with volumetric masses of the liver (VML) of various origin is presented. For successful differential diagnosis of VML and definition of rational surgical policy the algorithm of examination was considered with due regard for diagnostic stages, each of them being characterized by definite complex of tests. It is thought necessary to begin examination with noninvasive and highly informative tests.

[Diagnosis and therapeutic tactics in polycystic liver].

The results of clinical observations of 60 patients with polycystosis of the liver who had been treated or examined by the authors in the period from 1964 to 1989 were summarized. The clinical course of the disease was featured by scanty clinical signs: pains in the upper half of the belly and hepatomegaly were most frequent. The combination of diagnostic techniques for verification of surgical intervention necessity was established.

[Laboratory and instrumental diagnosis of echinococcosis during conducting mass screening and surgical treatment].

In the course of 15 years the authors conducted a comprehensive examination of over 13,000 patients for establishing the diagnosis and surgical treatment of hydatid disease; among these patients there were more than 3,000 who underwent operation, 1,280 who were examined for recurrence of the disease, and 5,000 who were subjected to periodical medical examination. The enzyme immunoassay and indirect hemagglutination test are the most reliable in the diagnosis of primary and recurrent hydatid disease and in periodical examination; the latex fixation test remains false-positive (16.9%) up to 3 years.
