|Abstract:||This is a retrospective yearly audit of EBUS performed in 2019 in a large teaching hospital, to assess diagnostic yield, adequacy, and use of rapid on-site evaluation (R.O.S.E.). |
Overall, 158 patients underwent EBUS procedure (187 lymph nodes, 44.9% women) with a mean age of 60.92yrs .
The overall inadequacy rate was 9.49% . ROSE was performed in 84.8% with a positive yield in 91.8%.
80.21% were ATS N2 stations (2, 4, 7). In 19% cases (30/158), 2 nodes or more where sampled.
Overall, 61.39% showed benign cytology, of which granulomas were identified in 26.58% .
Sarcoidosis suspected in 43 patients (49 lymph nodes) with a yield for granulomas of 79.1%..
Of the 111 EBUS performed for suspected malignancy, 38.74% were positive for pulmonary and extrapulmonary malignancies; 52.25% were benign; 7 showed granulomas (6.31%).
Metastatic small cell carcinoma was diagnosed in in 27.9%, pulmonary adenocarcinoma in 23.26% , squamous cell carcinoma in 11.6%, extrapulmonary malignancy in 32%; metastatic breast carcinoma was the commonest.
EBUS is a good tool for the diagnosis of both malignant and non-malignant hilar and mediastinal lymphadenopathy, with 79.1% yield for sarcoidosis and overall inadequacy rate of 9.49%. These samples can be used to assess for molecular targets.
