With laser it's possible to produce a radiation of definite wave length which is rich in energy. This energy is changed into heat during its impinge on tissue. Different effects (coagulation, vaporization) can be produced in dependence on wave length, the technical features of laser and the different interaction of laser light. In 8 patients with obstructive polypous carcinomas of rectosigmoid a complete passage-recovery could be achieved. The therapy was effective in 8 out of 11 patients with villous adenomas. One patient had a relapse into adenoma after half a year. With laser a distal rectostenosis at high degree could be widened at Morbus Crohn. Complications didn't appear. Indications of laser-therapy are explained. The laser-therapy is effective, not very risky but not cheap. Therefore it requires an application of overlapping subjects.
利用激光可以产生具有确定波长且能量丰富的辐射。这种能量在其撞击组织的过程中会转化为热量。根据波长、激光的技术特性以及激光与光的不同相互作用，可以产生不同的效果（凝固、汽化）。在8例直肠乙状结肠阻塞性息肉样癌患者中，实现了完全的通道恢复。该疗法对11例绒毛状腺瘤患者中的8例有效。1例患者在半年后复发为腺瘤。对于克罗恩病患者，激光可使高度的远端直肠狭窄变宽。未出现并发症。阐述了激光治疗的适应证。激光治疗有效，风险不大但费用不低。因此，它需要应用于重叠的病例。
