Progressive respiratory failure frequently cause serious dyspnoeas or asphyxias. It is possible a palliate treatment destroying and removing masses of endobronchial tumors. Good results are obtained with Yag Laser especially in case of polypoid obstructions. Our cases demonstrate the use of endobronchial electrocautery for the removal of large amounts of tumor in the trachea and in the bronchus. Our successes suggest a possible role for this technique in selected cases. These attempts were carried out through a fiberoptic bronchoscope passed through an endotracheal tube. Endobronchial applications of electrocautery are similar to those for Yag Laser, but electrocautery requires less expansive equipment. However, the role of direct cautery and the appropriate selection and duration of currents will only be acquired with experience by an already experienced endoscopist.
