Abstract:
Objective To evaluate the diagnostic role of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in the smear and culture negative tuberculosis.Methods The tuberculosis suspected patients with spu-tum-negative for three times and with hilar or mediastinal lymphadenopathy were randomly divided into 2 groups,study group received EBUS-TBNA and bronchoalveolar lavage group(BAL) examination,control group received BAL examination only.Chi-square test was used to compare their diagnostic sensitivity and negative predictive value.Results Totally 82 patients were included this study,40 patients were in control group and 42 in the study group.In the control group,tuberculosis was confumed in only 8 cases by means of bacteriological examination in the BAL fluid,27 were confirmed by the following surgery ordiagnostic treatment of anti-Tuberculosis,and the other 5 cases were diagnosis as other diseases; In the study group,tuberculosis was confirmed in 28 patients through bacteriological and pathological examination,8 were false negative and the other 6 were diagnosis as non-tuberculosis diseases.The diagnostic sensitivity in the study group was significantly higher than that in control group (77.8％ verus 22.9％,x2 =21.4,P ＜ 0.01 ) ; and the negative predictive value in the EBUS-TBNA group was also significantly higher than that in the BAL group (42.9％ VS 15.6％,x2 =3.97,P =0.046).Complications were similar inthese 2 groups,only 1 case of intervention required puncture site bleeding happened in the study group.Conclusion EBUSTBNA has a higher sensitivity and negative predictive value in the diagnosis of smear and culture negative pulmorary tuberculosis patients with hilar or mediastinal lymph nodes.This technique is a safe method with few complications than the traditional BAL examination.It may play an important role in the diagnosis of smear and culture negative tuberculosis patients.
