title: Characteristics and risk factor analysis of 410 cases of tracheobronchial tuberculosis.
abstract: The present study analyzed the characteristics and risk factors associated with tracheobronchial tuberculosis (TBTB) in 410 patients with TBTB. Retrospective analysis was performed on the clinical features, bronchoscopy performance, bacteriological examination, imaging and treatment of 410 patients who were diagnosed with TBTB using bronchoscopy. Among the 410 patients, 10 patients underwent chest X-ray which revealed two cases of atelectasis, eight cases of patch or spot shadows, three cases of cavity, one case of nodule and one case with no abnormalities. The remaining 400 patients underwent computed tomography chest scans and/or airway reconstruction examinations. Among all the lesion types, the cavity type was found to be the most likely to cause bronchial stenosis or obstruction, with statistically significant differences when compared with the congestion, stenosis or scar lesion types (P<0.01). Moreover, for the cavity type, there were 194 sites of obstruction prior to therapy; however, only 23 sites of obstruction remained following therapy. Furthermore, there were 34 sites without stenosis prior to therapy and 205 sites without stenosis following therapy. The number of sites of obstruction was significantly decreased and the number of sites without stenosis was increased upon therapy. These findings suggest that the cavity type is the most sensitive type to therapy among the five types of TBTB lesion.
