[Endoscopic laser therapy].

The Nd-YAG-laser is being used since ten years in gastroenterological endoscopy with good success. It can be used for treatment of bleeding lesions or lesions which potentially could bleed, for treatment of benign and malignant tumors, treatment of non-neoplastic stenoses and pathological changes in the region of the papilla. Own results with this treatment in 1033 patients are reported, demonstrating high efficacy of this method by improving quality of life and decreasing the number of surgical interventions necessary and also decreasing hospital lethality.
