21G和23G细针对超声引导下甲状腺结节穿刺标本满意率的比较

Comparison the sample satisfaction rate of 21 and 23 gauge needles used for the ultrasound-guided fine needle aspiration biopsy of thyroid nodules

目的比较21G和23G型号细针对甲状腺结节穿刺标本的满意率。方法 2015年1月至2015年2月到首都医科大学附属友谊医院超声医学科进行甲状腺穿刺的病例共123例,123个结节中每个结节分别用21G和23G针进行超声引导下细针穿刺抽吸活组织检查(US-FNAB),所有标本进行液基细胞学制片,将标本分为满意和不满意2种,21G和23G针穿刺的先后顺序按照随机表进行,比较21G细针和23G细针在进行甲状腺结节穿刺时标本的满意率。结果 21G针穿刺甲状腺结节的标本满意率87.8%(108/123),23G针穿刺甲状腺结节的标本满意率86.2%(106/123)。差异无统计学意义(χ2=0.045,P>0.05)。结论 23G细针和21G细针在甲状腺结节穿刺中取得标本的满意率相近,23G细针穿刺可以作为一种方法用于临床工作。

Objective To compare the sample satisfaction rate of 21 and 23 gauge needles used in the ultrasound-guided fine needle aspiration biopsy（US-FNAB） of thyroid nodules. Methods A total of 123 cases of thyroid puncture patients from January 2015 to February 2015 in our department were included in this study, each nodule was aspirated by both 21 G and 23 G needles guided by ultrasound, all specimens were produced by liquid-based cytology, the order of 21 G and 23 G needle was in terms of random table, samples were divided into two groups, satisfied or unsatisfied, then the satisfaction rate between 21 G and 23 G was compare. Results The satisfaction rate of 21 G needle aspiration of thyroid nodules was 87.8%, while The satisfaction rate of 23 G needle aspiration of thyroid nodules was 86.2%. There was no statistically significant difference between 21 G and 23 G needles in terms of the sample satisfaction rate（χ2=0.045, P〉0.05）. Conclusion The results of our study showed that FNA with 23 G needles can aspirate adequate material for cytopathological diagnosis. 23 G gauge needles may be used as a more secure method for US-FNAB of thyroid nodules in clinical work.
