[Treatment of tracheobronchial malignant tumors using a new high power diode contact laser (GaAlAs) system].

We treated ten patients with tracheobronchial malignant tumors using a new high power diode contact laser (GaAlAs) system (DIOMED 25, OLYMPUS) with a flexible bronchofiberscope (OLYMPUS BF IT200 or BF IT240). The total energy of the high power diode laser was 811 J, with a range of 64-3,960 J. With this method 85.
