超声引导穿刺活检的甲状腺结节定性诊断效果

Qualitative diagnosis effect of thyroid nodules guided by ultrasound guided biopsy

目的探讨并对比超声引导下穿刺活检与触诊法穿刺活检在甲状腺结节定性诊断中的价值。方法选择2012年9月-2016年9月期间天津市大港油田总医院诊治的100例甲状腺结节患者,随机分为对照组(触诊法穿刺活检)和观察组(超声引导下穿刺活检),每组各50例,通过比较两组穿刺活检结果、病理结果,进一步分析两组的敏感度、特异度、准确率、误诊率和漏诊率。结果与对照组相比,观察组对甲状腺结节良恶性诊断的敏感度、特异度、准确率均明显升高,而误诊率和漏诊率显著降低,差异有统计学意义(P<0.05)。结论超声引导下穿刺活检能够为甲状腺结节定性诊断提供客观的参考依据,成为非手术条件下获得病理学诊断的首选方法。

Objective To study and compare the value of the qualitative diagnosis of thyroid nodules between ultrasound guided and palpation biopsy. Methods The 100 patients with thyroid nodules in Tianjin General Hospital of Dagang Oil Field from September 2009 to September 2013 were randomized into the control group（palpation biopsy biopsy）and the observation group（ultrasound guided biopsy）with 50 patients in each group. The sensitivity,specificity and the rates of accuracy,misdiagnosis,missed diagnosis in the two groups were compared through the compare of the biopsy results and pathology results in the two groups. Results Compared with the control group,the sensitivity,specificity and the rates of accuracy in the observation group were significantly increased and the rates of misdiagnosis and missed diagnosis in the observation group were obviously reduced. The differences were statistically significant（P〈0.05）. Conclusion The ultrasound guided biopsy can provide the objective basis for the qualitative diagnosis of thyroid nodules and become the preferred method of non-operation conditions to obtain pathological diagnosis.
