Abstract: Objective To explore the clinical features of the patients with active pulmonary tuberculosis associated endobronchial tuberculosis(EBTB). Methods Clinical data on 97 active pulmonary tuberculosis cases associated EBTB were analyzed retrospectively. Results Cough(82.5%),sputum production(80.4%),fever(45.4%) and the different degree of haemoptysis or blood stained sputum(23.7%) were the most common chief complaints.The most common roentgenographic findings were atelactasis/detelectasis(44.2%) and parenchymal infiltration and/or consolidation(37.9%),and bronchial stenosis or obstruction,bronchiectasis,bronchial dissemination,bronchial air sign,mediastinal lymphadenitis and lymph nodes calcification were also demonstrated in chest CT.Sputum smear/culture of acid-fast bacilli positive rate was 63.9%.It was 83.3% in the patients with muti-lobar/segmental parenchymal infiltration and/or consolidation of Chest CT.Bronchoscopic Results showed the lesions were more likely to be seen in the main and lobe bronchi.Multi-trachea/bronchi were involved(81.4%) and several subtype forms of bronchoscopic finding co-existed.The positive rate of bronchoscopic brushing smear for acid-fast baccili and biopsy was 55.9% and 69.4%,respectively.Only 18 patients received interventional bronchoscopic treatments.6 patients with bronchial stenosis/obstruction and atelactasis received the treatments of fiberoptic broncoscopic balloon dilation.As a result,stenosis was alleviated in 5 patients. Conclusions Symptoms were non-specific in the patients with active pulmonary tuberculosis associated EBTB.Chest CT was very useful in evaluating bronchial lesions such as stenosis or obstruction and the change of mediastinal lymph nodes. Bronchoscopy was still an important method to diagnose active pulmonary tuberculosis associated EBTB.Bronchoscopic findings showed that leision occurred on Multi-trachea/bronchi and overlapping subtype forms existed.Bronchial stenosis can be improved effectively by balloon dilation techniques.
