Application Of Endoscopic Lasers For Operations In Gastro-Intestinal Tract

We have described our experience in the application of high energy argon and Nd:YAG lasers for endoscopic surgical manipulations. Laser was used for the removal of polyps with a wide base, villi tumours in colon, for the elimination of scar strictures in colon anastomosis, for the formation of primary-delayed colon anastomosis and for the removal of timoral stenosis in esophagus and in colon. Laser therapy has certain advantages over other endoscopic manipulations: long-term and immediate results are better. One can use this therapy in combination with others (radial therapy, surgical treatment). We have worked out a classification of polyps and stenosing tumours in the digestive system to determine indications for laser endoscopy and to choose the best parameters of laser irradiation.
