[Endoscopic evaluation of endobronchial tuberculosis in children].

The aim of this study was to determine the role of fiberoptic bronchoscopy (FB) in pulmonary tuberculosis in children. We assessed bronchoscopic findings of 36 procedures performed in 30 children who presented the following abnormalities on chest films: lobular or segmentary atelectasis (17), paratracheal or parahilar adenopathies (14), parenchymatous consolidation (9) and localized hyperinflation (5). Premedication for FB included intravenous atropine and diazepam plus ketamine for sedation, as well as lidocaine 2 and 5% in aerosol form for topical anesthesia. FB results showed that involvement was endobronchial in 29 patients. In the 18 patients with X-rays suggestive of endobronchial tuberculosis (EBT), the diagnosis was confirmed by FB. Significantly, EBT was found by FB in 11 (36.6%) patients with no clinical or radiological signs of such involvement. EBT was in the early stages in 3 (10%) patients and was advanced in 8 (26.6%). M. tuberculosis was isolated in 9 (30%) of the 30 patients. Culture was of bronchoalveolar lavage in three, of gastric lavage in four and of endobronchial biopsy in two. We conclude that FB is a safe, important tool for the confirmation of EBT in the management of pulmonary tuberculosis in children. It serves as a guide for the start of steroid treatment, especially in children with no radiological suggestion of EBT.
