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

ABSTRACT

Bronchoscopy is useful as a diagnostic and therapeutic procedure in children with Tuberculosis (TB) disease complicated by airway obstruction. It is needed in children when surgical intervention may be required for airway compression, when drug resistance is suspected, and to rule out an alternative diagnosis for airway obstruction. Bronchoscopy with bronchoalveolar lavage (BAL) should be performed when other, less invasive samples cannot be collected, or when they fail to provide useful diagnostic information. BAL specimens collected at bronchoscopy can be tested using molecular TB assays and mycobacterial culture. The aim of this review is to evaluate the role of bronchoscopy in the diagnosis and management of pulmonary TB in children, and, specifically, to review the role of interventional bronchoscopy. A search of electronic databases was undertaken using the online databases PubMed, Ovid MEDLINE, EMBASE, Google Advanced Scholar, and Web of Science to identify relevant literature. The search was limited to pediatrics, pulmonology, bronchoscopy, and pediatric pulmonary tuberculosis for all articles published in English on pediatric bronchoscopy between 2010 and 2020. Recent advances in pediatric bronchoscopy was included, as well as recent research on improving the diagnosis with the use of interventional bronchoscopy. The role of bronchoscopy in pediatric pulmonary tuberculosis has changed during the last decade, from a simple method of collecting samples for bacteriological conformation to an more sophisticate procedure. New methods are available for collecting samples, which includes the use of Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and also better methods of bacteriological conformation. Interventions are now possible; not only to improve the diagnostic abilities of bronchoscopy but also to diagnose, manage, and follow-up upon airway-related complications. Bronchoscopy services remain limited in resource-limited countries due to the high cost of equipment.
