[Ultrasound in a differentiated treatment approach for liver diseases].

Objective: Prospective assessment of the proposed diagnostic algorithm aimed at increasing the reliability of diagnosis of diffuse and focal liver diseases, reducing diagnostic invasiveness, economic costs, developing management strategy of patients with liver tumors and early diagnosis of hepatocellular carcinoma.

Material And Methods: A prospective case-control study included 336 patients with a preliminary diagnosis of diffuse focal liver damage for the period from January 2015 to April 2019.

Results: The authors described a diagnostic algorithm for focal liver lesions based on various ultrasound modes including gray-scale scanning (B-mode), Doppler ultrasound and pulse-wave Doppler.

[Immediate outcomes of pancreatoduodenectomy after different digestive reconstruction procedures].

Objective: To study the immediate results of pancreatoduodenectomy depending on digestive reconstruction procedure.

Material And Methods: We analyzed 242 patients who underwent pancreatoduodenectomy for the period from January 2013 to December 2019. There were 32 combined procedures: 28 (11.

[Percutaneous endoscopic gastrostomy].

Percutaneous endoscopic gastrostomy (PEG) was developed in 1980. Since that time this method has become preferable for long-term enteral nutrition. PEG is an effective and relatively safe procedure for enteral nutrition of patients with impaired enteral feeding.

[Early outcomes of open, laparoscopic and robot-assisted pancreatoduodenectomy].

Aim: To study immediate results of open, laparoscopic and robot-assisted pancreatoduodenectomy for malignancies.

Material And Methods: There were 158 patients with cancer of biliopancreatoduodenal area. Open procedures were performed in 118 cases, laparoscopic in 17, robot-assisted pancreatoduodenectomy - in 23.

[METHOD FOR DETERMINING EROSIVE LESIONS OF THE GASTRIC MUCOUSA IN CHILDREN WITH JUVENILE ARTHRITIS].

To detect the clinical diagnostic criteria for non-invasive diagnosis of erosive gastritis in children with juvenile arthritis have been studied the 92 children aged 9 to 16 years (mean age-13,9 ± 2,3 years) with verified diagnosis of juvenile arthritis, of whom 10 had erosive gastritis (group 1) and 82 without erosions (group 2). A comparison of the groups on 23 grounds by analysis of contingency tables and the subsequent discriminant analysis, has developed a new non-invasive method for determining the erosive lesions of the mucous membrane of the stomach in children with juvenile arthritis, including a score of history, complaints and the results of laboratory studies the level of the G-17, pepsinogen I, pepsinogen II, and the ratio of pepsinogen I to pepsinogen II, the presence of autoantibodies to the H+, K+/ATPase of the parietal cells of the stomach, the test for occult blood "Colon View Hb and Hb/Hp". Developed a diagnostic table, including 11 features with scores each.

Tunable laser diodes for the 1250-1650 nm spectral range.

A series of tunable laser diodes was developed with emission wavelength in spectral range 1250-1650 nm. This paper describes the configuration and basic characteristics at temperatures from 5 to 80 degrees C.
