Treatment of peptic ulcer of the stomach and duodenum with helium laser
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.
