[Morphology of the reparative processes after the arrest of gastric hemorrhages using various lasers]. 1981

V I Eliseenko, and O K Skobelkin, and T M Titova

Morphological changes in the stomach of 40 heparinized dogs with acute gastric hemorrhages from experimental ulcers and 22 patients with acute gastrointestinal hemorrhages were studied immediately and at remote intervals after laser photocoagulations performed by continuous laser irradiation. After laser irradiation, typical changes in morphological structures developed and were accompanied by the appearance at the site of the bleeding ulcers of coagulation necrosis and coagulative thrombi of arrosive arteries conducive to hemostasis. Laser wounds healed with the formation of aseptic productive inflammation without considerable inflammatory infiltration and edema of the adjacent tissues. Reparation of the mucous membrane ends by 30--45 days after coagulation with regeneration of the muscular layer of the mucosa and without any scar in the submucous layer.

UI MeSH Term Description Entries
D007834 Lasers An optical source that emits photons in a coherent beam. Light Amplification by Stimulated Emission of Radiation (LASER) is brought about using devices that transform light of varying frequencies into a single intense, nearly nondivergent beam of monochromatic radiation. Lasers operate in the infrared, visible, ultraviolet, or X-ray regions of the spectrum.
