Abstract:

Objective To evaluate the combination of endobronchial ultrasonography with guide sheath (EBUS-GS), transbronchial lung biopsy (TBLB), and rapid on-site evaluation (ROSE) for the diagnosis of bacteriologically-negative pulmonary tuberculosis (PTB).Methods A total of 70 patients with suspected PTB were enrolled from January 2020 to December 2020 based on clinical symptoms, abnormal radiographic findings, sputum bacteriological examination (smear and culture), and initial sputum molecular detection negative results. The patients randomly divided into two groups: group A underwent EBUS-GS-TBLB (n=34), and group B underwent EBUS-GS-TBLB+ROSE (n=36). The diagnostic rates and biopsy numbers were evaluated between the two groups.Results 16 patients with PTB were detected in group A, and 22 in group B. After the joint ROSE, The PTB diagnostic rate improved from 47.06% to 61.11%(P=0.238), and the mean numbers of biopsy decreased from 4.53±0.50 to 3.08±0.60(P<0.01). The accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of ROSE for the diagnosis of PTB were 86.36%, 86.67%, 85.71%, 92.86%, and 75.00%, respectively, with no serious complications.Conclusion The combination of EBUS-GS-TBLB and ROSE can improve the diagnostic rate, and reduce the biopsy numbers, which is thought of an effective and safe novel diagnostic modality.
