The role of bronchoscopy in the diagnosis and management of pediatric pulmonary tuberculosis

Abstract

Pulmonary tuberculosis (TB) is the commonest clinical form of childhood TB occurring in approximately 80% of cases. Traditionally, bronchoscopy in pediatric TB suspects was used to collect specimens for mycobacterial culture using especially bronchoalveolar lavage. New data have described the role of bronchoscopy as a more comprehensive instrument for the diagnosis and management of pulmonary TB in children. Flexible bronchoscopy is an important intervention to evaluated airways disease, collect samples for culture, relieve critical threatening airway obstruction and aid in the management of complicated pulmonary TB disease in children. Airway involvement in children suspected of pulmonary TB has been described in 41-63% of cases. The commonest airways involved are bronchus intermedius, left main bronchus and the trachea. Bronchoscopy is safe in children with severe airway obstruction. As bronchoscope images improve, the working channel size increases new applications for bronchoscopy will be developed making them more applicable in small children.
