After an analysis of the complex interweaving reactions of laser on biological materials, the laser applications in medicine and surgery are reviewed by the author. In ophthalmology its use is regular but not yet optimal. In otological applications the first results are good. In dermatology favorable results are obtained but the absence of special device had stopped his development. In surgery and endoscopy the best wave length must be chosen in reference to their hemostatic action and cutting, nevertheless in gastroscopy and bronchoscopy the laser seems to bring new therapeutic solutions. In odontology the pulsed lasers are dangerous for therapy but the holographic technique is a fertile research area. The author conclude to the necessary development of researches on the fundamental problems set by the biomedical applications of lasers.

[Use of a flexible laser-beam (Yag) for endoscopic treatment of some tracheobronchial lesions (author's transl)].

After the use for several years of an endoscope which enables electro-coagulation in the treatment of some tracheo-bronchial lesions, the limitations and accidents of this method were compared with clinical results and experimental research. Results seem to indicate that the flexible laser beam can considerably improve therapeutic possibilities. This beam, conducted by a flexible fiber, could easily be used by medico-surgical teams who already possess the suitable endoscopic material, or material that could readily be adapted to this method.

[Use of a laser beam (YAG) with a flexible fiber for endoscopic treatment of some broncho-tracheal lesions (author's transl)].

For several years we employed an endoscope permitting electro-coagulation in the treatment of some broncho-tracheal lesions and were able to observe the limits and accidents involved in this method. When compared with clinical results (work of Freche in ORL, laser CO2) and after experimental research, the use of a flexible laser beam (YAG) seems to bring about a noteworthy increase in therapeutic possibilities. This flexible fiber beam could easily be used by some medico-surgical teams who already possess appropriate of easily adaptable endoscopic equipment. Clinical studies are in progress.
