We treated 160 patients (141 men and 19 women, the age of patients was from 18 to 67 years) with gastric and duodenal ulcers using a helium-neon laser LG-75 with an output power range from 15 to 35 mW. Laser radiation was injected into a quartz monofilament 4 mm in diameter and 3 m in length using a transient focusing device. The power of radiation at the output of the fiber was 85% of the initial one. In 127 patients the ulcer (size - 0,8±0,2 cm) was localized in the bulb of duodenum, in 33 patients - in the stomach (0,7±0,1 cm). The efficacy of treatment was judged by the dynamics of clinical, radiological, endoscopic and morphological parameters. Acid-producing function of the stomach was investigated by intragastric pH-metry, motor function - by electro gastrography. The therapeutic manipulations were performed daily or every other day for 5 min at a power density at the end of the glass fiber of 1.5-2X103 wt-m-2. In all cases laser therapy was started after histological and cytological examination of biopsy material.
