CT引导下Magnum活检枪经皮肺活检诊断肺部肿块的临床研究

Clinical study of diagnosis of lung mass by CT-guided percutaneous lung biopsy through Magnum biopsy gun

目的探讨CT引导下Magnum活检枪在经皮肺肿块穿刺活检术中的临床应用价值。方法对胸片和CT检查提示为肺部肿块的187例患者行CT引导下Magnum活检枪经皮肺穿刺活检。结果 187例(100%)穿刺成功;179例(95.7%)获得正确诊断,恶性肿瘤162例,占90.5%,其中腺癌72例,鳞癌67例,小细胞癌12例,大细胞癌5例,转移性肺癌4例,腺鳞癌2例;结核10例;炎性假瘤5例;嗜酸性肉芽肿2例。并发症主要为气胸和出血,其中气胸发生率为18.2%,咯血及痰中带血发生率为9.1%,肺组织出血占12.3%,5例胸腔少量积血,2例穿刺处皮下血肿。结论 CT引导下Magnum活检枪经皮肺穿刺活检术操作简便,诊断准确,并发症少,值得临床推广。

Objective To study the clinical application value of CT-guided Magnum biopsy gun in percutaneous needle biopsy of lung mass.Methods CT-guided percutaneous needle biopsy of lung mass through Magnum biopsy gun was conducted to detect 187 patients with lung mass suggested by chest radiography and CT.Results 187 cases（100%） got successful puncture,179 patients（95.7%） was confirmed with 162 cases of malignant tumor,accounting for 90.5%,including 72 cases of adenocarcinoma,67 cases of squamous cell carcinoma,12 cases of small cell carcinoma,5 cases of large cell carcinoma,4 cases of metastatic lung cancer and 2 cases of adenosquamous carcinoma;10 cases of tuberculosis;5 cases of inflammatory pseudotumor and 2 cases of eosinophilic granuloma.The major complications were pneumothorax with incidence rate was 18.2% and bleeding,which incidence rate of hemoptysis and bloody sputum was 9.1%,lung tissue bleeding,12.3%,5 patients with small amount of pleural hemorrhage and 2 cases of subcutaneous hematoma at puncture site.Conclusion CT-guided percutaneous needle biopsy of lung mass through Magnum biopsy gun is easy and simple to handle,with accurate diagnosis and less complications,and is worthy of promotion.
