objective To assess the efficacy of applying bronchofibroscope facilitated by microwave and sacculus to heal tracheal and bronchial tuberculosis with ulcer caseous necrosis and granulation generation. [Methods]: Select 143 cases of tracheal and bronchial tuberculosis patients (ulcer caseous necrosis and granulation generation), then use microwave to solidify the ulcer caseous objects and granulation on the surface of the air tube of tracheal bronchus. Next, incise it with the current of 40W-55W. If the caseous objects and granulation cause airway constriction, use microwave to conduct incision and make sacculus expand. If the caseous objects and granulation cause airway obstruction and the opening is extremely narrow, put off microwave incision and avoid occluded scar from growing too quickly. Under this circumstance, sacculus expansion should be conducted first, then cut granulation around the opening. If the scar is completely occluded, surgery should be done in such case. The diameter of sacculus needs to be expanded to 0.5, 0.8, and 1.2cm, with its pressure from 3 to 6. [Results]: Al the patients of 143 cases go through microwave treatment and sacculus expansion. In two cases among al, the patients with caseous objects and granulation blocked in the right intermediate bronchus are conducted microwave incision, but they fail to folow the prescription of treatment strictly, so in the recovery time the occlusion can’t be expanded in time. In three cases among al, the left main bronchus is severely narrow and the opening is stil closed partly, nevertheless the situation of the patients’ difficulty in breathing is improved obviously. In four cases among al, brackets are inserted in the patients who have tracheal stricture, but the stricture stil exists and granulation grows on tubal wal. After conducting microwave incision 3 to 4 times and sacculus expansion 7to 8 times, the condition of the patients is basicaly wel til now. [Conclusio]: The research indicates that bronchofibroscope facilitated by microwave and sacculus is an important approach to heal tracheal and bronchial tuberculosis. This approach can solve the patients’ difficulty in breathing quickly, clean up caseous objects and granulation in airway, and expand the stricture. This achievement can’t be reached by applying medication to the whole body. According to 2 to 3years’ observation, the patients’ bronchial tuberculosis doesn’t relapse. In spite of the growth of granulation, bronchus stricture again after expansion, more operation times and great pain for the patients, the efficacy of this treatment is comparably apparent and is approved by the patients.
