Comparison of 21‐gauge and 22‐gauge aspiration needle during endobronchial ultrasound‐guided transbronchial needle aspiration

Abstract

There were no differences in the diagnostic yield between the 21G and 22G needles during EBUS-TBNA. The preserved histological structure of the samples obtained by the 21G needle may be useful for the diagnosis of mediastinal and hilar adenopathy of unknown aetiology which may be a challenge with the 22G needle.
