Résumé
Patients with undiagnostic pleural effusions are routinely examined by conventional medical thoracoscopy under the white light (WL). The endoscopic appearance of pleural diseases under WL could be misleading. Narrow-Band Imaging (NBI) has been applied as an interesting and effective diagnostic tool for endoscopy. However, there is also controversy about its value in the application of thoracoscopy. The objective of this study was to investigate the diagnostic value of NBI technology during thoracoscopy. Patients with undiagnosed pleural effusions admitted to our hospital between September 2017 and September 2019 were enrolled. During the thoracoscopy, we performed WL mode first and then NBI. Pictures of endoscopic real-time lesions were recorded under two modes, and at least five pieces of tissue were taken, respectively, on pleura lesions. Biopsy specimens were respectively taken for pathologic analysis. Diagnostic sensitivity, specificity were calculated to compare with pathologic results. 100 eligible patients were enrolled, including 63 with malignancy, 23 with tuberculous pleurisy, 3 with systemic disease and 11 with the negative condition. Compared with pathological results, the sensitivity of WL was 91.01%, and NBI 84.27%; while the specificity of WL was 27.27%, and NBI 81.82%. Compared NBI with WL, the former's specificity is superior to the latter's, which is statistically significant (P < 0.05). The advantage of NBI lies in its high specificity. It's useful to diagnose unknown pleural effusions in clinical practice. With better visualization of blood vessels, we can enhance the accuracy of biopsy and reduce the risk of unexpected bleeding arose from the biopsy.

BACKGROUND
Patients with undiagnostic pleural effusions are routinely examined by conventional medical thoracoscopy under the white light (WL). The endoscopic appearance of pleural diseases under WL could be misleading. Narrow-Band Imaging (NBI) has been applied as an interesting and effective diagnostic tool for endoscopy. However, there is also controversy about its value in the application of thoracoscopy.

The objective of this study was to investigate the diagnostic value of NBI technology during thoracoscopy.
METHODS
METHODS
Patients with undiagnosed pleural effusions admitted to our hospital between September 2017 and September 2019 were enrolled. During the thoracoscopy, we performed WL mode first and then NBI. Pictures of endoscopic real-time lesions were recorded under two modes, and at least five pieces of tissue were taken, respectively, on pleura lesions. Biopsy specimens were respectively taken for pathologic analysis. Diagnostic sensitivity, specificity were calculated to compare with pathologic results.

RESULTS
100 eligible patients were enrolled, including 63 with malignancy, 23 with tuberculous pleurisy, 3 with systemic disease and 11 with the negative condition. Compared with pathological results, the sensitivity of WL was 91.01%, and NBI 84.27%; while the specificity of WL was 27.27%, and NBI 81.82%. Compared NBI with WL, the former's specificity is superior to the latter's, which is statistically significant (P < 0.05).
CONCLUSIONS
CONCLUSIONS
The advantage of NBI lies in its high specificity. It's useful to diagnose unknown pleural effusions in clinical practice. With better visualization of blood vessels, we can enhance the accuracy of biopsy and reduce the risk of unexpected bleeding arose from the biopsy.
