Abstract

Background

Current data for the utility of radial endobronchial ultrasound (EBUS) in investigating peripheral lung lesions (PLLs) has been restricted to populations with low pulmonary tuberculosis (TB) incidence. The aim of this study was to assess the diagnostic utility of radial EBUS with guide sheath in the diagnosis of peripheral lung lesions in Singapore, a high TB incidence setting.

Methods

A post-hoc database analysis was performed. 123 consecutive patients with computed tomographic evidence of PLLs who underwent radial EBUS guided bronchoscopy were included.

Results

The final diagnosis was malignancy in 76 cases and benign in 44 cases. Radial EBUS guided bronchoscopy had a sensitivity of 65.8 % for malignancy, positive predictive value of 100 %, negative predictive value of 62.9 %, and a diagnostic accuracy of 82.5 %. 22 patients had a final diagnosis of pulmonary TB. The diagnostic sensitivity for pulmonary TB was 77.3 %, with a positive predictive value of 100 %, negative predictive value of 95.2 % and a diagnostic accuracy of 95.8 %. Overall, 58.8 % of pulmonary TB cases relied on histology to make an early diagnosis.

Conclusion

Radial EBUS guided bronchosopy is useful in investigating PLLs in a high TB incidence setting. Our data also suggests that radial EBUS is a more rapid diagnosis technique for tuberculous lesions.
