Abstract
- Laser emits a light characterised by being monochromatic, phased and collimated. Since the beginning of the '80s the fibers ND-YAG laser, whose energy may be transmitted by quartz fibres, is the type principally used for therapeutic bronchoscopy. It may be used to coagulate or to vaporize endoluminal lesions. The effect looked for depends on the level of density of power selected. During rigid bronchoscopy, YAG laser is usually applied in the coagulation mode, with a weak liberation of energy. Further resection is then achieved mechanically with the rigid tube or forceps. For malignant lesions the laser has a palliative action in eliminating endoluminal tumour mass. Its use has overturned the management of progressive tracheal or bronchial asphyxia. Outside emergencies, its action can be combined with radio and chemotherapy. For benign lesions its action may be curative. The laser is however poorly adapted for extrinsic compression and for infiltrating lesions where other more appropriate endoscopic methods should be used.
