[Endoscopic electro- and laser surgery in diseases of the trachea and bronchi].

Endoscopic interventions with the use of a AIH-laser and high frequency currents were carried out in 72 patients with tumors and cicatricial stenoses of the trachea and bronchi. Intraoperative complications occurred in 4 patients. The immediate results were good and satisfactory in 92.8% of patients. The authors conclude that the use of a polypectomic loop is advisable in removal of tumors on a narrow base, those on a wide base are best destroyed with a laser; the use of an AIH-laser beam in the treatment of cicatricial stenosis is undesirable.
