[The plasm welding of the digestive system organs in experiment].

The plasm welding of the gut organs--perspective trend, which permits to increase the surgeon possibilities in performance of operative intervention. The results of operations, performed on large intestine and stomach, trusts, that it is possible to apply the streams of the high temperature gas plasm for the tissues dissection and connection. There are such advantages of the method, as the operation time shortage, simplicity in manipulating "Plasmomed" apparatus, absence of foreign bodies in the connection zone, high degree of hemostasis achieved. After the operation there was observed rapid restoration of the main structure elements in the large intestine and stomach wall, localized in the plasm welding zone. There was elaborated and tested a new method of the living tissues welding, and the processes, occurring in tissues within the plasm welding application zone, were studied up.

[Experimental substantiation of the method of biological tissue welding in surgical hepatology].

Application of the welding method for biological tissues in hepatobiliary surgery was experimentally substantiated. In 14 pigs (25-30 kg body mass) resection of one hepatic lobe, using electric welding method, was done. In control group (4 pigs) the similar operative intervention was accomplished, using conventional method. Application of the electric welding method guarantees secure hemostasis and cholestasis, do not causes specific pathological changes in the adjacent region of affection tissues, speed of restoration of the structures damaged exceeds such in application of the suturing method.

[Experimental application of electrocautery in biliary surgery].

The testing of a new nonsuture electrothermic method of biliary system tissues connection was conducted in laboratory animals--rabbits and pigs. Reactions of tissues and cells in zone of electric influence and the gallbladder suture, remote reactive changes in the operation zone were studied up. In application of the proposed method of the regeneration processes inhibition and specific pathological changes in surrounding tissues were not noted, speed of the damage structure restoration was comparable with such in the tissues connection using suture materials.

[Experimental elaboration and perspectives of application of electric welding of the live tissues].

In experiment on pigs, rabbits and white rats there was examined method of electric welding (electrothermoadhesion) of live tissues--intestine, stomach, gallbladder and bladder, peritoneum, elements of mesentery, liver, spleen. We distinguish among "welding" of the hollow organs wall with restoration of their passability and "overwelding" of masses of the tissues with production of coagulational furrow, along which resection of necessary parts is executed. According to data of morphological investigations obtained the security of the method was established. Peculiarities of welding suture of tissues were studied. The method is introducing in the clinical practice actively due to its simplicity and safety in sutureless connection of tissues.

[Experimental models for testing new surgical methods and materials].

The main models of operative interventions, used for examination of new surgical suturing and nonsuturing methods of the tissues connection are presented; the animals applied in such a purpose, the anesthesia support schemes for every kind of laboratory animals were noted.

[Experimental-clinical substantiation of the use of atraumatic suture material "metallatravm" in the surgery of bile ducts].

High efficacy of home sutural material "Metallatravm" application while biliary anastomoses creation was proved in experiment on 180 white rats. One-layer extramucosal interrupted suture application proved as a long-term one. In 35 patients with biliary ducts obstruction high efficacy of applied material was noted. Ligature cholelithiasis and stenosis recurrences were not observed.

[Use of Soviet fibrin adhesive in liver surgery in experimental animals].

The results of a comparative experiment for studying the native glue composition on a fibrin base, which possesses the hemostatic and adhesive properties and has the influence on the processes of regeneration, and modern synthetic medical glues are presented. The essential advantages of a fibrin-based glue were revealed.

[Mechanism of the hemostatic effect of alginates].

It was revealed that the presence of alginate accelerated the final stage of blood coagulation--fibrinogen-into-fibrin conversion. This was conditioned by the structure and stereochemical properties of an alginate.
