[Therapeutic application of Nd-YAG laser treatment for the chest surgery area].

Laser therapy is now a well-established procedure and an accepted method of treatment in thoracic surgery. Therefore, using Nd-YAG laser (Model Md-50 Y) at hospital, we had discussed for the technique and its indication of laser therapeutic application against chest diseases. The following results were obtained; 1) The first object of endoscopic laser therapy is to keep the normal air-way from tracheobronchial stenosis or its bleeding as fast as possible. 2) As this laser techniques are not only the quick expansion of the residual lung but also relative absence of air-leak and blood loss, they are indicated for open lung biopsy or partial resection of metastatic lung tumors, particularly in patients with poor pulmonary function. 3) In conjunction with standard surgical technique of chest surgery, this laser treatment provides numerous other possibilities which facilitate the achievement of the therapeutic goal of surgical operation on the lungs.
