| PURPOSE : The purpose of this study is to evaluate whether ultrasound (US)-guided fine-needle non-suction technique
is more comfortable and useful than the conventional suction technique for the cytopathologic evaluation
of thyroid nodules.
MATERIALS and METHODS : Cytopathologic findings at consecutive fine-needle non-suction biopsies of 415 thyroid nodules
in 262 patients were retrospectively reviewed. The procedure was performed by non-suction technique
with 25-guage needle under US guidance. For each nodule, the biopsy was repeated up to two passes.
RESULTS : Cytopathologic diagnostic rate was 89.4% (371/415), and inadequate specimen rate was 10.6% (44/415).
Among 371 adequate specimens, the nodules were benign in 282 (68%), malignant in 55 (13.3%), and suspicious
for malignant or follicular neoplasm in 34 (8.2%). Among 44 inadequate specimens, nodules were calcified
in 9, cystic in 2, and solid or mixed echoic in 33.
CONCLUSION : US-guided fine-needle non-suction technique is more comfortable than and as useful as the conventional
suction technique for the cytopathological evaluation of thyroid nodules. |
