目的:比较B超引导下细针吸取穿刺和传统细针吸取穿刺在甲状腺肿块性质确定中意义。方法:使用B超引导下细针吸取穿刺(UG-FNAB)和传统细针吸取穿刺技术(c-FNAB)对225例甲状腺肿块进行穿刺活检,然后进行涂片,染色,镜检,结合临床作出细胞学诊断,并与组织切片诊断对照,比较两种方法的确诊率。结果:在UG-FNAB检测病例中59.3%的结节位于甲状腺右叶,40.7%肿块位于左叶和峡部。87%的患者甲状腺机能正常,结节最长径平均为2.8±1.1 cm,部分病例符合甲状腺恶性肿瘤的超声影像学改变。在本研究中诊断为甲状腺乳头状癌的病例细胞学和组织学特点均符合甲状腺癌形态学特点。在225例研究病例中,总确诊率为72.89%(164/225),其中UG-FNAB组确诊率为90.58%(77/85),C-FNAB组确诊率为62.14%(87/140),两组确诊率比较有显著性差异(P<0.05)。结论:本组研究数据显示比较C-FNAB,UG-FNAB在诊断甲状腺复杂性结节中具有更高的确诊率,特别是在C-FNAB方法不能得出明确诊断时。
OBJECTIVE: To compare the significance of fine needle aspiration and traditional needle aspiration in the determination of thyroid mass under the guidance of B ultrasound. Methods: A total of 225 cases of thyroid masses were biopsied by fine needle aspiration (UG-FNAB) and conventional fine needle aspiration (c-FNAB) guided by B-ultrasound, followed by smears, staining, and microscopy. Cytological diagnosis, and compared with the diagnosis of tissue sections, compared the accuracy of the two methods. RESULTS: Of the UG-FNAB cases, 59.3% were located in the right thyroid lobe, and 40.7% were located in the left lobe and isthmus. 87% of patients had normal thyroid function, and the longest diameter of the nodules averaged 2.8±1.1 cm. Some cases were consistent with ultrasound imaging changes of thyroid malignancy. The cytological and histological features of the cases diagnosed as papillary thyroid carcinoma in this study were consistent with the morphological features of thyroid cancer. Among the 225 study cases, the total diagnosis rate was 72.89% (164/225), with a diagnosis rate of 90.58% (77/85) in the UG-FNAB group and a 62.14% (87/140) diagnosis rate in the C-FNAB group. There was a significant difference in the rate of diagnosis between the two groups (P<0.05). Conclusion: The data from this study show that C-FNAB and UG-FNAB are more accurate in diagnosing complex thyroid nodules, especially when the C-FNAB method cannot provide a definitive diagnosis.
