Paper Abstract

Involving high-power lasers into clinic medicine significantly extended the possibilities of the endoscopic surgery, which in a number of cases becomes a serious competitor to the traditional surgical methods of treatment1,2 Endoscopic surgeiy lowers the intervention risk, reduces the terms of patient's hospital treatment, the patient s activity can be restored in a shorter post-operational period and a possibility appears of carrying out complex operatirns in ambulance conditions. Endoscopic operations nowadays are made using mostly a continuous YAG: Nd laser with operating wavelength 1.06 tm. However, there exist serious restrictions on use of this type of radiation for the endoscopic surgical interventions at the gastrointestinal organs. They are connected with wall perforation risk . Endoscopic using of a cO-laser, which works as an excellent scalpel in general surgety, is connected with technical difficulties of 10.6 jim radiation transmission by a flexible light guide. Moreover, the the hemostatic properties of this kind of radiation are rather limited. The specified above reasons stipulated that the practical medicine be interested in solid YAG-cr-Tm: Ho lasers with wavelength range of 2 im and their application in the endoscopic surgeiy. This report consists of two parts: experimental and clinical ones. The experimental data presents the character of pulse-repetitive YAG:Nd and YAG:cr,Tm,Ho lasers radiation action in comparison with the radiation from cwYAG:Ndlaser. The second part presents the results ofthose lasers application to endobronchial surgery.
