[Treatment of peptic ulcer patients using yellow laser light]

A group of 26 patients received a course of endoscopic therapy for gastroduodenal ulcers using yellow laser light on copper vapours. Treatment was carried complexly with traditional drug therapy. Phototreatment (0.58 mcm) of the mucosal defects was carried out every other day, single dose equalling 2--3 joules; 12 +/- 2.0 days from the beginning of treatment were required for complete scarring of the duodenal ulcerations and 11.8 +/- 8.0 days for healing of gastric ulcers.
