超声引导下穿刺活检对颈部淋巴结病变的诊断价值

目的 探讨超声引导下穿刺活检对颈部淋巴结病变的诊断价值.方法 超声引导下应用18 G组织切割针经皮穿刺活检颈部淋巴结病变共178例,取出目标组织者为取材满意,否则为取材不满意.以活检病理肯定诊断或随访6个月的结果为最后诊断.结果 超声引导下颈部淋巴结穿刺活检的取材满意率为96.7%.对转移肿瘤诊断的敏感性、特异性和准确性均为100%;对淋巴结核、淋巴反应性增生诊断的敏感性、特异性和准确性分别为81.7%、99.1%、92.1%和82.9%、94.1%、91.6%.结论 超声引导下经皮穿刺活检对颈部淋巴结病变的诊断具有很高的价值,但不同种类疾病,其诊断价值有差异.

Diagnostic value of ultrasound-guided percutaneous biopsy for neck lymphadenopathy

Objective To investigate the diagnostic value of ultrasound-guided percutaneous biopsy for neck lymphadenopathy. Methods One hundred and seventy-eight patients with neck lymphadenopathy underwent ultrasound guided biopsy. A biopsy was considered technically successful if a targeted tissue was obtained. Final diagnosis was made based on either the conclusive pathological diagnosis or the result of follow-up for more than six months. Results The rate of technically successful biopsy was 96.7% , and the sensibility, specificity and accuracy for the metastases of cervical lymph node were 100%, 100% and 100% , respectively, while for the tuberculosis of cervical lymph node and the reactive hyperplasia of lymph nodes, the sensitivity, specificity and accuracy were 81.7% , 99. 1%, 92. 1% and 82.9% , 94. 1% , 91. 6% respectively. Conclusion Ultrasound-guided percutaneous biopsy has high value for diagnosis of cervical lymphadenopathy, but for different diseases, the diagnostic value is different.
