超声引导下经皮肺胸膜穿刺自动活检

Ultrasound guided percutaneous automatic biopsy of pulmonary and pleural diseases

目的探讨超声引导下经皮肺、胸膜自动活检的组织学诊断准确性和并发症。方法回顾性总结分析９４例外周型肺占位和胸膜病变９８次Ｂ超引导下经皮穿刺自动活检的结果。病例包括肺癌３２例，胸膜间皮瘤２０例，转移性肺癌５例，肺或胸膜结核２７例，肺炎性病变１０例。使用带１８Ｇ内槽式穿刺针的自动活检装置，在Ｂ超引导下行病变穿刺活检，术后观察气胸、出血等并发症发生情况。结果９８次穿刺均一次取材成功，８７例做出了明确的组织学分型诊断，组织学确诊阳性率为９２．６％（８７／９４），穿刺后并发症中气胸和出血各２例（占２．１％），均无须手术处理而愈。结论Ｂ超引导下经皮肺、胸膜穿刺活检是一种安全可靠的确诊肺外周型占位和胸膜病变的方法。

bjective\ To determine the diagnostic accuracy and complication rate of Ultrasound (US) guided percutaneous automatic biopsy of pulmonary and pleural diseases. Methods\ Ninetyeight consecutive biopsies were performed on 94 patients who suffered from pulmonary or pleural diseases included 32 lung cancers, 20 mesothelimas, 5 metastases, 27 tuberculosis and 10 inflammatory foci. Under US guided, a 18guage core needle with automatic biopsy device was used. After procedure, the complications (such as pneumothorax and bleeding) were noticed. Results\ The procedure of puncture was successful in all patients and the positive rate histologically was 92.6% (87/94). After procedure, pneumothorax was discovered in two patients and bleeding in two. These patients were rescured without operation. Conclusions\ US guided percutaneous automatic biopsy is a safe and reliable method for diagnosing pulmonary and pleural diseases.
