The use of laser surgical equipment permits to simplify considerably a method of gastric seromyotomy. On the basis of the results of treating 38 patients, the optimal parameters of laser energy, used in dissection of the gastric wall, are recommended, the advantages and shortcomings of the different sources of radiation are studied.

The principles of surgical techniques of operations with the use of carbon dioxide laser were developed on basis of the authors' personal experience of 8 years in surgical interventions on 65 patients. The stages of the operative approach, cholecystectomy, choledochotomy, +choledocho-duodeno-anastomosis, papillosphincterotomy, and sterilization of the operative wound and intraabdominal abscesses are illustrated by professionally drawn illustration-diagrams. Laser separation of the gallbladder from the liver takes 220 +/- 35 sec, laser hemostasis and cholestasis of the gallbladder bed--245 +/- 40 sec, laser choledochotomy--17 +/- 8 sec, laser duodenotomy--33 +/- 9 sec. No specific complications were encountered after laser interventions.

A technique of laser seromyotomy was developed as a method for vagus denervation for the treatment of gastroduodenal ulcers. Soviet Raduga neodymium YAG laser and foreign Medilaz and Flexilas units were employed as sources of laser irradiation. The operation was performed in the 'contact scalpel' mode with the use of Soviet sapphire tips. The developed technique permits seromyotomy that results in better hemostasis and lower risk of gastric submucosal layer involvement vs. electronomo suggested earlier by Taylor, an English surgeon. Twelve patients were operated on; one developed intraperitoneal hemorrhage that ceased independently.

It was revealed, that irradiation in the experiment of the spore-forming and non-spore-forming microbial cultures, irrespective of the density of growth, was accompanied by their complete destruction in density of radiant energy of the "Scalpel-1" CO2-laser equal to 32.2 J/cm2 (power density--32.2 W/cm2) and more, and exposure for 1 s.
