[Features of radio wave tissue dissection in surgical practice]. / Osobennosti radiovolnovoi dissektsii tkanei v khirurgisheskoi praktike.

Results of experimental and clinical investigations of using radioknife "Surgitron" for dissection and coagulation of tissues were compared. In 145 experiments the possibility to dissect different tissues (skin, muscles, fascia) and parenchymatous organs of the abdominal cavity was studied. The specific course of reparative processes was analyzed at different periods after operation. In clinical conditions the radioknife was used for operative interventions on 520 patients: in 91 cases the device was used for dissection and coagulation of hollow organs and in 73 cases--of parenchymatous organs of the abdominal cavity, in 356 patients radioknife was used for plastic operations. The radioknife "Surgitron" was established to be very good for dissection of tissues. The coagulating effect was weak. The zone of undesirable lateral necrosis was negligible, and often it was absent that makes favorable conditions for the reparative processes. On the basis of clinical and experimental investigations it was established that using radioknife "Surgitron" is indicated and expedient in plastic and esthetic surgery because it is in this field where the positive properties of radiowave action can have maximal realization taking into account the requirements of the means and quality of dissection of tissues.

[Physical methods of dissection and coagulation in surgery]. / Fizicheskie sposoby dissektsii i koaguliatsii v khirurgii.

The paper presents 20-year experience in using various devices for tissue dissection and coagulation of such as electrosurgical ones EN-57M, Efa-0201 (Russia), Karl Storz-endoscope (Germany), Force-300, Force-FX, LigaSure ("Valley-lab", USA), Erbotom ICC 350 ("Erbe"), Argo-3000 ("Soring", Germany), a Surgitrone radioknife ("Ellman", USA), ultrasonic Auto Sonix devices ("Auto Suture", USA), a harmonic Ultracision scalpel ("Ethicon Endo-Surgery", USA), laser Scalpel-1 and Romashka-1 devices (Russia), plasma Fakel-01 and Prometey devices (Russia). The results of 424 experimental studies and clinical application of different energies in 1683 patients are analyzed. The influence of different types of energy on tissue and reparative processes were revealed, morphological changes were studied. Advantages and shortcomings of each type of energy are demonstrated, recommendations for their optimum application are formulated.

[Use of a plasmatic surgical device for hemostasis in injuries of parenchymal organs]. / Primenenie plazmennoi khirurgicheskoi ustanovki dlia gemostaza pri povrezhdeniiakh parenkhimatoznykh organov.

The article presents experimental grounds and clinical experiences for using a plasma device in 58 patients. Sufficiently high efficiency and safety of the method used during surgical procedures for arrest of bleedings from parenchymatous organs is proved.

[Experimental development of methods of organ-sparing operations in mechanical injuries of the spleen]. / Ob eksperimental'nykh razrabotkakh metodov organosokhrania-iushchikh operatsipri mekhanicheskikh povrezhdeniiakh selezenki.

Experiments in dogs have shown that injuries of the spleen in these animals are of another character than those in men. Even in severe injuries hemorrhage spontaneously stops within several minutes without any surgical procedures and the spleen wounds heal rather quickly. Dogs easily endure traumas of the organ. The authors make a conclusion that results of the development of methods of treatment of injuries of the spleen in experiment can not give a correct estimation of possibilities to effectively use them for humans.

[Characteristics of the healing of wounds of the stomach, intestines and liver after exposure to the plasma scalpel]. / Osobennosti zazhivleniia ran zheludka, kishki i pecheni pri vozdeistvii plazmennogo skal'pelia.

Results of experimental application of plasma surgical device UMPR-20 in operations on the stomach, intestine and liver in acute and chronic experiments are described. Coagulating properties of the plasma jet were detected responsible for reliable hemostasis in dissection of the parenchymatous organs. As compared with other surgical devices (electroknife, ultrasonic scalpel, laser "Scalpel-1" device) the zone of injury of the underlying tissues is much less and makes up 0.2-0.3 mm. The plasma surgical device UMPR-20 has good prospects in using during operations on parenchymatous organs and for treatment of their injuries.

[Comparative data on the healing of surgical wounds of the stomach made by ordinary, laser and ultrasonic scalpels]. / Sravnitel'ye dannye o zazhivlenii operatsionnykh ran zheludka, nanesennykh obychnym, lazernym i ul'trazvukovym skal'pelem.

The article presents comparative morphological data on the healing of operative wounds on the stomach of rabbits made by an ordinary, laser and ultrasound scalpels. In all the cases the wound was sutured by a one-row interrupted sero-muscular stitches. Clear distinctions in the healing of postoperative gastric wounds made by different scalpels were established. The formation of a zone of coagulative necrosis, followed by rejection of necrotic masses was invariably noted after the laser and ultrasound scalpels. These zones were not so considerable after dissecting the stomach with an ordinary scalpel. No incompetent sutures, failure of their hermetic quality or any other complications in the process of scar formation were detected in all the series.

[Clinico-morphologic evaluation of regenerative processes in gastric incisions made with a laser scalpel]. / Kliniko-morfologicheskaia otsenka regenerativnykh protsessov v rane zheludka, nanesennoi lazernym skal'pelem.

Clinical observations and experiments in animals enabled the authors to conclude that after operations on hollow organs of the abdominal cavity the healing of wounds made by a usual scalpel developed more favorably than of those made by a laser scalpel.
