Abstract

Objective: The aim of this study is to compare the results of three gauge (G) needles (22G, 23G and 25G) in terms of cell amount in thyroid fine needle aspiration (FNA).

Subjects and methods: In the retrospective study, a total of 443 patients undergoing FNA for the first time between 2017 and 2018 were included in the study, and assigned to 3 groups with 22-gauge, 23-gauge and 25-gauge needles, respectively.

Results: The cell amount of a suspicion for the four diagnosis groups, including malignancy and malignant, benign nodules, follicular of undetermined significance (FLUS), and follicular neoplasia was mainly in the range of 0-10000, 0-300, 0-150, and 500-2500, respectively. The cut-off values of 22G needle 20000, 300, 1000, and 2500, while the cut-off values of 23G and 25G were 10000, 400, 1000, and 2500; 5000, 400, 1500, and 2000, respectively for the four diagnosis groups.

Conclusion: Large-gauge needles resulted in more cellular specimens than small-gauge needles only in the cases of malignant tumors. Small-gauge needles resulted in a higher comfort level of the patients, and had no difference in cell number in nodules with abundant blood supply, compared with large-gauge needles.

不同规格甲状腺细针穿刺的定量分析。

目的:比较22G、23G、25G三种规格(G)针在甲状腺细针穿刺(FNA)中细胞数量的差异。对象和方法:回顾性研究纳入2017 - 2018年首次行FNA患者443例，分为3组，分别使用22号、23号和25号针。结果:恶性及恶性、良性结节、未确定意义滤泡(FLUS)和滤泡瘤变4个诊断组的可疑细胞数量分别主要在0 ~ 10000、0 ~ 300、0 ~ 150、500 ~ 2500之间。22G针的截止值为20000、300、1000、2500,23G、25G针的截止值为10000、400、1000、2500;四个诊断组分别为5000、400、1500和2000。结论:仅在恶性肿瘤病例中，大针比小针检出更多的细胞标本。小针头使患者的舒适度更高，并且与大针头相比，在血供丰富的结节中细胞数量没有差异。
