[Possible uses of laser in gastroenterology].

In the therapy of certain benign and malignant changes in the intestinal tract the laser stood the test. The absolute necessity of its use is limited, among others by existing alternative methods, so that a broadly disseminated equipment is not necessary. By the development of new types of laser and better handling systems (fibres with diffuse emission, fibres with lateral delivery of light and so on) its possibilities of application will enhance.
