[Healing of extensive acute gastric ulcer after chemical burn by Helium-Neon laser (endoscopic and morphologic investigation)].

The paper provides the results of endoscopic and morphologic follow-up of healing of extensive corrosive gastric ulcer in He-Ne laser therapy of 34 patients (512 gastric biopsies). Laser radiation of ulcer reduces frequency of stenosis in healing outcome as well as treatment duration, creates conditions for healing without leukocytic fusion of necrotic tissues. Effectivity of laser therapy is determined by the time of its start and regularity.
