Interventional bronchoscopy in the treatment of bronchial stenosis due to tranchebronchial tuberculosis

Abstract

Objective To assess the efficacy of interventional bronchoscopic techniques in treating bronchial stenosis due to tracheobronchial tuberculosis. Methods Data of 35 patients who were admitted to our hospital with a diagnosis of tracheobronchial tuberculosis and treated with microwave, balloon dilatation and stent placement from January 2006 to December 2010 were analyzed retrospectively. The dyspnea index and FEV1 were evaluated. Results The effective rate of interventional bronchoscopic techniques was 91.4%. Twenty-five patients undergoing microwave and ball dilatation treatment and 7 patients undergoing stent placement were cured with interventional bronchoscopy.Pulmonary functions of FEV1 were improved from (1.54 ± 0.21) L to (2.48 ± 0.32) L(P ＜ 0.05) before and after interventional bronchoscopy respectively. There was no significant complications in patients who were treated with interventional bronchoscopy. Conclusions Interventional bronchoscopic techniques were effective and safe for bronchial stenosis treatment. Key words: Bronchoscopy; Intervention; Tracheobronchialtuberculosis; stenosis; Efficacy
