超声引导甲状腺结节细针穿刺针数对取材满意率的影响

目的　比较在超声引导下甲状腺结节细针穿刺活检中不同穿刺针数的标本满意率，为临床操作提供依据。 方法　纳入我院95例患者，共计106个实性或实性为主的甲状腺结节，随机分为1针组、2针组和3针组，均在超声引导下完成对甲状腺实性成分的细针穿刺活检术，标本送细胞病理学诊断，依据Bethesda分类标准，将BethesdaⅠ类定义为不满意，BethesdaⅡ~Ⅵ类定义为满意，比较不同穿刺针数的标本满意率。 结果 结节标本总体满意率为92.5%（98/106），1针组、2针组、3针组的标本满意率分别为90.2%（37/41）、93.9%（31/33）、93.8%（30/32），三组差异无统计学意义（P＞0.05）。 结论　对于实性或以实性为主的甲状腺结节，超声引导下细针穿刺的针数对取材的影响不明显，穿刺1针可以达到和2针、3针相当的标本满意率。

Effect of ultrasound-guided fine-needle passes number on sampling satisfaction rate

Objective　To compare the sample satisfaction rate of different needle passes in ultrasound-guided fine-needle aspiration biopsy of thyroid nodules, and provide the basis for clinic operation. Methods　Ninety-five patients with 106 solid or mainly solid thyroid nodules were included in our hospital and randomly divided into a one-needle passes group, a two-needle passes group, a three-needle passes group. Fine needle aspiration biopsy of thyroid was performed under ultrasonic guidance. The obtained specimens were sent for cytopathological diagnosis which was classified according to the Bethesda System. Bethesda I was defined as unsatisfactory, and Bethesda Ⅱ~Ⅵ were defined as satisfactory. The satisfaction rate of specimens with different number of passes needles was compared.　Results　The overall satisfaction rate of nodule samples was 92.5% (98/106). There were no statistical differences in the satisfaction rate among the one-needle passes group, two-needle passes group, and three-needle passes group (90.2%, 93.9%, and 93.8%, respectively, P>0.05).　Conclusions　For solid or mainly solid thyroid nodules, the number of needle passes guided by ultrasound has no significant effect on sampling and the satisfaction rate of specimen with one needle passes is equivalent to that with 2 or 3 needles.
