Coagulation of Intrabronchial Tumors by Transbronchoscopic Microwave Electrodes

Abstract

We performed transbronchoscopic microwave electrodes for two cases of respiratory tract tumors. One case had had a left complete atelectasis for bronchial tumor, after microwave electrodes had been carried out surgery. The otherhad had a right complete atelectasis for epidermoid carcinoma ; we performed transbronchial biopsy for diagnosis with using microwave electrodes for occasional bronchial bleeding.
We experienced less bleeding and smoke, a larger area could be coagulated in single procedure than high power laser ablation therapy. This method was effective in treating airway obstruction, especially in patients for administrating oxygen for respiratory failure because of less its ignitable.
