[Use of nonhazardous laser radiation for treating the complications of patients undergoing radical surgery for esophageal and stomach cancer].

Helium-neon laser irradiation of sparing intensity (fluence 1.5-2.0 x 10(3) W/m2) was given to 15 patients with erosive-ulcerous complications ( anastomositis , reflux-esophagitis and peptic ulcer of anastomosis) following radical surgery on the stomach. Irradiation was delivered via the optical fibre of the endoscope biopsy duct. A pronounced analgetic effect of laser irradiation was observed. In 2 cases, peptic ulcers of anastomoses became completely covered with epithelium. The same effect was obtained in 11 out of 13 cases of erosive reflux-esophagitis.
