Low-intensive lasers in the treatment of peptic gastric and duodenal ulcers.

Abstract Pharmacochemical achievements have brought about considerable improvement in treating peptic ulcers. But possible side effects demand a very cautious approach to the administration of every new drug, and stimulate the search for nontraditional treatment. In 638 patients who were treated by semiconductor laser transcutaneously (external irradiation), an average term of ulcer healing was 11.5 days, that is, half the time required for controls. The healing process under laser therapy depends on the disease gravity as well as the diameter and depth of the ulcer. Morphologically, we noted a quick restoration of microvessels in the ulcer area. The most optimal parameters of laser irradiation are chosen with the help of biophotometry.
