Endobronchial tuberculosis

Abstract

Endobronchial tuberculosis is defined as tuberculous infection of the tracheobronchial tree. Although clinical features differ between various types and stages of endobronchial tuberculosis, common symptoms are cough, hemoptysis, sputum production, wheezing, chest pain, fever and dyspnea. Endobronchial tuberculosis is difficult to diagnose, because the lesion is not evident in the chest radiograph. Computerized tomography is very useful in evaluating bronchial lesions such as stenosis or obstruction. The most important goal of treatment in active endobronchial tuberculosis is the eradication of tubercle bacilli. The second most important goal is prevention of bronchial stenosis. Corticosteroid therapy for prevention of bronchial stenosis in endobronchial tuberculosis remains controversial, but the best results are associated with minimal delay in the initiation of steroid treatment. In inactive disease, treatment to restore full patency is appropriate. As steroids or other medication are unable to reverse stenosis from fibrous disease, airway patency must be restored mechanically by surgery or endobronchial intervention. Aerosol therapy with streptomycin and corticosteroids is useful in treatment against active endobronchial tuberculosis. Time to healing of ulcerous lesions is shorter, and bronchial stenosis is less severe in patients on aerosol therapy. Progression to bronchial stenosis may be prevented if the therapy is initiated as soon as possible.
