Abstract: Objective  To discuss the efficacy of airway obstruction suffered from endobronchial tuberculosis through interventional therapy under bronchoscope.  Methods  Eighty-two patients with airway obstruction suffered from endobronchial tuberculosis were given normal antituberculosis treatment, in the same time they received interventional therapy under bronchoscope. According to the degree of obstruction, flushing, removing by forceps clip, or highfrequency electric coagulation were chosen and then isoniazid was administrated in bronchial lumens.  Results  Of 82 patients, 54 cases had airway complete unobstruction, 26 had mild airway narrow, and 2 had no improvement.  Conclusion  The efficacy of intervention therapy under electronic bronchoscope in patients with endobronchial tuberculosis is definite．This method has few complications，it can improves effectively the airway obstruction．
