Conventional Bronchoscope With BAL vs. Thin Bronchoscope With BW to Diagnose Pulmonary TB

Tuberculosis, Pulmonary Clinical Trial

Official title:
Bronchoalveolar Lavage Using a Conventional Bronchoscope vs. Bronchial Washing Using a Thin Bronchoscope to Diagnose Pulmonary Tuberculosis: a Prospective Randomized Trial

Clinical Trial Summary

This study aims to compare the diagnostic yield of bronchoalveolar lavage (BAL) using a thick conventional bronchoscope and bronchial washing (BW) using a thin bronchoscope in the diagnosis of pulmonary tuberculosis.

Clinical Trial Description

In patients with suspected pulmonary tuberculosis (TB), confirm the presence of TB bacilli through sputum testing is essential for diagnosis. However, the sensitivity of sputum specimens is suboptimal, and some patients may be unable to produce sputum. In such situations, it is traditionally known that obtaining samples through bronchoscopy increases the diagnostic yield of pulmonary TB. Typically, the method of using a thick, conventional bronchoscope to perform bronchial washing (BW) or bronchoalveolar lavage (BAL) is commonly employed. However, a drawback of the conventional bronchoscope is its inability to reach close to peripheral pulmonary TB lesions due to its larger diameter. Recent studies have reported an increased diagnostic yield for pulmonary TB when using a thin bronchoscope for BW compared to using a thick, conventional bronchoscope for BW. However, a direct comparison with the method of performing BAL (BAL may have a higher diagnostic yield compared to BW) using a conventional bronchoscope has not been conducted. This study aims to prospectively compare the diagnostic yield for pulmonary TB between BAL using a conventional bronchoscope and BW using a thin bronchoscope. ;
