Since the mid-seventies the application of laser in gastroenterology for the treatment of haemorrhages and tumours has stood the test. At present the neodym-YAG-laser is the most important endoscopically applicable laser. The sources of laser radiation, the biophysical effects of laser and their fields of application, the technical and methodical and security-technical aspects as well as own divice-technical solutions and the indications in the application of the endoscopic laser therapy are described. In 12 out of 15 patients with a villous adenoma of the rectum the treatment was successful. In 9 patients with a high-degree stenosing rectosigmoid carcinoma (diameter 0.5 cm) the passage could be restored (diameter after treatment 1.3 cm). Complications did not appear. The laser therapy is effective, poor in risks, but not cheap.
自七十年代中期以来，激光在胃肠病学中用于治疗出血和肿瘤已得到验证。目前，钕钇铝石榴石激光是最重要的可在内窥镜下应用的激光。本文描述了激光辐射源、激光的生物物理效应及其应用领域、技术方法和安全技术方面，以及自身的设备技术解决方案和内镜激光治疗的应用指征。15例直肠绒毛状腺瘤患者中有12例治疗成功。9例高度狭窄的直肠乙状结肠癌患者（直径0.5厘米）经治疗后肠腔得以恢复（治疗后直径为1.3厘米），未出现并发症。激光治疗效果显著，风险较低，但费用不低。
