B超引导下细针穿刺活检判断甲状腺结节性质的应用价值

Application Value of B-ultrasound-guided Fine-needle Biopsy to Determine the Nature of Thyroid Nodules

目的:探讨B超及B超引导下的细针穿刺活检判断甲状腺结节性质的临床应用价值。方法:选取2018年1月~2019年10月我院收治的甲状腺结节患者200例,所有患者均接受B超检查和B超引导下细针穿刺检查,以手术病理结果为金标准,对比两种检查方式的灵敏度、特异度、阳性预测值、阴性预测值和准确率。结果:(1)200例患者共239个结节,手术病理结果证实良性结节64个,恶性结节175个;(2)B超引导下细针穿刺检查的灵敏度、特异度、阳性预测值、阴性预测值、准确率明显高于B超检查(P<0.05);(3)B超引导下细针穿刺对不同大小结节的诊断的灵敏度、特异性、阳性预测值、阴性预测值、准确率均优于B超检查(P<0.05)。结论:B超引导细针穿刺活检判断甲状腺结节性质的应用价值明显优于B超检查。

Objective:To explore the clinical value of B-ultrasound and B-ultrasound-guided fine-needle biopsy in the diagnosis of thyroid nodule.Methods:200 cases of thyroid nodule from January 2018~October 2019 were collected and all patients were examined by B-ultrasound and B-ultrasound-guided fine needle aspiration,take the surgical pathological results as the gold standard,the sensitivity,specificity,positive predictive value,negative predictive value and accuracy of the two methods were compared.Results:(1)There were239 nodules in 200 patients,64 of which were benign and 175 of which were malignant;(2)The sensitivity,specificity,positive predictive value,negative predictive value and accuracy of fine needle aspiration under the guidance of B-ultrasound were significantly higher than those of B-ultrasound(P<0.05);(3)The sensitivity,specificity,positive predictive value,negative predictive value and accuracy of fine needle aspiration under the guidance of B-ultrasound for the diagnosis of nodules of different sizes were all better than that of b-ultrasound(P<0.05).Conclusions:B-ultrasound-guided fine-needle biopsy is an ideal method for the diagnosis of thyroid nodules which is worth popularizing.
