[Endoscopic laser treatment of neoplasm and tubulovillous adenoma of the rectosigmoid. Initial experiences and review of the literature].
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.
