Endobronchial surgery of trachea and bronchi.

Bronchoscopic operative interventions were performed in 57 patients. We used photocoagulation with neodym-YAG-Laser, electrosurgery with fibroscopic diathermic snare and mechanical removal of endobronchial neoplasms. The most effective method was the laser photocoagulation, which permits removal of benign tumors, carcinoids, massive cicatrical tracheal stenosis and noninvasive bronchial cancer, help in restoring the lumen of main airways in case of nonoperable malignant tumors.
