Yield of conventional transbronchial needle aspiration (cTBNA) before and after introduction of endobronchial ultrasound.
There was significant increase in the diagnostic yield of cTBNA after introduction of EBUS.
Fig 2.
Learning curve of transbronchial needle aspiration (TBNA) over a 10-year period.
The proportion of representative lymph node sampling as well as diagnostic yield has increased over time.
Table 2.
Diagnostic yield before and after introduction of EBUS.
In this analysis, the initial 100 cTBNA cases after introduction of EBUS are included in the after EBUS period and is further stratified based on the clinical diagnosis.
