Abstract

In 2 years 53 patients with tumors of the tracheobronchial tree have been treated by photocoagulation therapy. Forty cases of them were with different types of cancer and 13 cases with benign lesions of the trachea or bronchi. As a laser source we used an Nd:YAG laser, MBB, Germany. At first the tumor was irradiated with a power of 25 - 30 W, following power up to 90 W. The median energy dose was 3,500 J/sq cm for each patient. The treatment was executed under local anesthesia with a rigid or flexible bronchoscope. In all of the cases with benign tumors we obtained a stable positive effect. In 15 cases of carcinoma we attained a recanalization and restoration of the ventilation to the treated area -- 37.5%. The only complication due to the procedure was the death of one patient with a tracheal cancer and myasthenia gravis. Photocoagulation therapy is an effective method for benign tumors. In cases with carcinoma this therapy is used with palliative purpose -- recanalization of the bronchus. Laser endobronchial therapy shows an immediate positive effect in the treatment of airway obstruction.
