[Clinical efficacy of ct-guided transthoracic needle biopsy of peripheral lung lesions].

Objective: To evaluate the effectiveness of a step-by-step protocol for GT-guided transthoracic biopsy in verification of peripheral lung tumors.

Material And Methods: A retrospective analysis of the results of GT-guided transthoracic biopsies of focal lung neoplasms was performed between October 2019 and December 2020. The analysis included the results of 176 biopsies in 158 patients.

Diagnostic approach and treatment specificity in patients with focal lesions of the biliopancreatic area complicated by mechanical jaundice.

Pancreatoduodenal resection (PDR) represents one of the most demanding procedures which is required in patients with a tumoral lesion at this level. The aim of the present article was to report the results of 272 patients submitted to such surgical procedures. All patients were divided into two groups: the main group, for whom the optimized decompression algorithm was used (n=112) and the control group, for whom preparation for PDR was carried out according to generally accepted standards (n=160).

[Experience of simultaneous laparoscopic cholecystectomy and gynecologic operations performance in conditions of "withous gas" laparoscopy in patients of high operation-anesthesiology risk].

The results of laparoscopic cholecystectomy performance in a combination with laparoscopic gynecologic operation on the background of concomitant cardiovascular and pulmonary diseases were analyzed in 67 patients. In 26 patients (main group) the original lifting system was used, 41 (control group)--operated on classical technology. Optimal operative accesses variants a defined, carboxyperitoneum influence on the central hemodynamics in the postoperative period, time of restoration of patients, frequency of postoperative complications is studied.

[Etiologic and immunologic characteristics of the influenza A1 epidemic in the Khabarovsk region in November--December 1977].

The etiology of an influenza outbreak which had occurred in Khabarovsk since 14 November, 1977 was elucidated. The largest number of cases was recorded among children and adolescents (under 22 years of age). Virological studies during the epidemic yielded 90 strains of influenza virus which were found to be antigenically quite close to A1 virus (HINI) which had circulated in this country in 1947-1956.
