Tuberculosis Diagnosis: Bronchoscopy Adds Little Information to Bacteriologic Tests

February 5, 2003

Researchers in Israel found that bronchoscopic testing is of limited utility for the diagnosis of pediatric pulmonary tuberculosis. Haim Bibi and colleagues at Barzilai Medical Center in Ashkelon and Bikur Holim Hospital in Jerusalem performed a study to "evaluate the effectiveness of fiberoptic bronchoscopy in the diagnosis of PTB," according to the report.

The investigators evaluated the utility of fiberoptic bronchoscopy in 80 children with suspected PTB and 342 control children with non-TB pulmonary illnesses. They found external compression of the right main bronchus in significantly more children with suspected PTB than in controls, 32 out of 80.

However, study data showed, mycobacterium tuberculosis was found in bronchoalveolar lavage fluid cultures from only three of the 80 children. Other physical anomalies such as laryngotracheomalacia were significantly more common in control children. The full report, "Should Bronchoscopy Be Performed in the Evaluation of Suspected Pediatric Pulmonary Tuberculosis?" was published in Chest (2002;122(5):1604-1608).

"Bronchoscopy in children with suspected PTB has a low yield and does not significantly aid bacteriologic confirmation," Bibi and colleagues concluded.
