Denervation of the gastric acid-producing zone by a gastric wall laser seromyotomy.

The application of various surgical laser devices offers the possibility for significant simplification of the technique of the selective denervation of a gastric acid-producing zone proposed by Tylor as the gastric wall seromyotomy. The application of laser technique results in decreased operative time, a wide range of surgical practice, less operative bleeding, and more reliable denervation. Operations performed in 38 patients provide a basis for recommending optimal parameters of laser energy for the gastric wall incision and reveal the advantages and disadvantages of different irradiation sources.

Resection of abdominal hollow organs by laser.

During a ten-year period 642 abdominal hollow organ resections have been performed by means of a new, original technique--that is, CO2 laser irradiation combined with specially designed instrumentation. This resulted in a remarkable decrease in postoperative morbidity and mortality. The article describes the laser procedure.

The abdominal surgery the Laser-"scalpel" should be used in combination with special instruments, to direct the ray, to protect medical personnel, surrounding tissue and organs. Complete haemostasis, sterility and biological welding of the different layers of stomach and gut enables the surgeon to make use of one layer anastomoses. Laser-photocoagulation of bleeding ulcers is the method of choice in serious ill patients.
