[Indications and results of using lasers in the trachea and bronchial system].

The Nd-YAG-laser is an ideal tool for surgery within the narrow bronchial system, provided indications, contraindications and a safe technique are observed. Complications of advanced tumors in the central bronchial system can be averted and patients can be treated by adjuvant therapy with reasonable median and long-term prognosis. In many cases of benign lesions patients can be spared the risks of major thoracic surgery. Complications are comparatively rare.
