Abstract
This study aims to compare the differences in sampling satisfaction rates between 5 mL syringe and 22G percutaneous transhe-patic cholangiography(PTC)needles in fine-needle aspiration(FNA)to provide economical and reasonable needle selection.From Janu-ary 2021 to March 2022,187 patients with thyroid nodules(a total of 200 nodules)who underwent ultrasound-guided FNA were punctured using 22G PTC and 5 mL syringe needles once for each nodule,and the sample was sent for pathological examination.The sample satisfac-tion rate of the two methods was statistically analyzed,and factors affecting the sample satisfaction rate were determined.Results demon-strated that the overall sample satisfaction rates of 5 mL syringes and 22G PTC needles were 83％and 85％(P＞0.05),respectively.The sat-isfaction rates of the two specimens were 92.6％and 91.1％(P＞0.05)among 136 nodules with poor blood supply.For 64 nodules with rich blood supply,the satisfaction rate of both specimens was significantly lower than that of the nodule with poor blood supply(P＜0.05),and that of the 5 mL syringe needle was significantly lower than that of the latter(62.5％vs.71.8％,P＜0.05).The results suggest that satisfac-tory sampling results can be obtained using either a 5 mL syringe or 22G PTC needles.The 22G PTC needle is more likely to yield FNA re-sults if the nodule is rich in blood supply.
