Diagnostic Yield of Transbronchial Histology Needle Aspiration in Patients with Mediastinal Lymph Node Enlargement

Abstract

The diagnostic yield of TBNA relied mainly on cytology specimens, despite the use of a histology needle. Representative histology specimens could only be obtained in 28/106 patients (26%). Since TBNA was performed in a general hospital by different bronchoscopists, this procedure is useful in the workup of lung cancer patients with enlarged lymph nodes.
