Abstract

PURPOSE
To assess the difference in the cytological adequacy of ultrasonography (US)-guided fine needle aspiration cytology (US-FNAC) for cervical lymphadenopathy using 21 and 23 gauge needles.
MATERIALS AND METHODS
US-FNACs were separately performed on two cervical lymph nodes and in each patient using 21 gauge (group A) and 23 gauge (group B) needles, respectively. We used 4 grade classifications for the cytological analysis of each slide and compared the cytological adequacy of US-FNAC for cervical lymphadenopathy in the two groups.
RESULTS
We performed US-FNACs on 58 cervical lymph nodes from 29 patients, with a cytological adequacy of 69.0%. The number of adequate cytological results was 19 (65.5%) in group A and 21 (72.4%) in group B, and the diagnostic adequacy did not differ significantly between the two groups (Mann-Whitney test, p = 0.574).
CONCLUSION
There was no statistically significant difference in the cytological adequacy of US-FNAC for cervical lymphadenopathy according using of 21 and 23 gauge needles.
