目的对超声引导下甲状腺结节细针穿刺活检的临床应用及质量控制予以分析和探讨。方法对2014年1月-2015年12月医院收治的甲状腺结节患者68例进行回顾性分析,分析超声引导下甲状腺结节细针穿刺活检的结果和超声诊断结果,并与手术病理与随访结果进行对比,得出假阳性率及细针穿刺活检诊断的灵敏度、特异度及准确率。结果 68例患者经超声引导下甲状腺结节细针穿刺活检的阳性病例24例,44例。灵敏度为75.0%(18/24),特异度为81.8%(36/44),准确率为82.4%(42/51),假阳性率为18.2%(8/44)。细针穿刺活检诊断甲状腺结节的灵敏度为91.7%(22/24),特异度为95.5%(42/44),准确率为94.1%(64/68)。结论对甲状腺结节患者进行超声引导可对穿刺目标的结节进行正确的选择,对甲状腺结节经过超声引导在实行细针穿刺活检具有十分显著的效果,对细针穿刺过程中的各个环节的质量进行控制,可很好地提升该技术水平,值得在临床上进一步的推广和使用。
Objective To analyze and discuss the clinical application and quality control of ultrasound guided fine needle aspiration biopsy of thyroid nodules. Methods A retrospective analysis was performed on 68 patients with thyroid nodules admitted from January 2014 to December 2015 in our hospital. The results of ultrasonography guided fine needle aspiration biopsy and ultrasound diagnosis were analyzed. The results were compared with those of surgical pathology and follow-up For comparison, the false positive rate and sensitivity, specificity and accuracy of fine needle aspiration biopsy were obtained. Results 68 cases of ultrasound-guided thyroid nodules fine needle aspiration biopsy in 24 cases, 44 cases. The sensitivity was 75.0% (18/24), the specificity was 81.8% (36/44), the accuracy was 82.4% (42/51) and the false positive rate was 18.2% (8/44). The sensitivity of fine needle aspiration biopsy in diagnosing thyroid nodules was 91.7% (22/24), the specificity was 95.5% (42/44) and the accuracy was 94.1% (64/68). Conclusions Ultrasound guided thyroid nodule can select the correct nodule for the puncturing target. Ultrasound guided thyroid nodule has a very significant effect on the fine needle aspiration biopsy. Quality control, can well enhance the level of technology, it is worth in the clinical further promotion and use.
