目的评价CT引导下经皮肺穿刺活检术在肺内占位性病变诊断中的价值。方法选取45例经影像检查确定为肺部占位性病变的患者,采用CT引导下经皮穿刺切割或抽吸取得标本进行病理学检查。结果穿刺成功率100%,其中43例获得准确诊断,诊断准确率为95.6%;其中恶性肿瘤21例(鳞癌7例、腺癌5例、肺泡癌1例、转移癌8例),良性病变22例(结核19例、炎性假瘤2例、错构瘤1例)。并发症发生率6.7%,包括少量气胸2例,轻微咯血1例,均不需特殊处理。结论 CT引导下经皮肺穿刺活检术操作简便、安全,诊断准确性高、并发症少,可作为肺内结节病变的常规诊断手段。
Objective To evaluate the value of CT guided percutaneous lung biopsy in the diagnosis of space occupying lesions in the lung. Methods Forty-five patients who were diagnosed as space-occupying lesions by imaging were selected and pathologically examined by CT-guided percutaneous cutting or aspiration. Results The success rate of puncture was 100%, of which 43 cases were diagnosed correctly, the diagnostic accuracy was 95.6%. Among them, 21 cases were malignant tumor (squamous cell carcinoma in 5 cases, adenocarcinoma in 5 cases, alveolar carcinoma in 8 cases, metastatic carcinoma in 8 cases), benign lesion 22 cases (tuberculosis in 19 cases, inflammatory pseudotumor in 2 cases, hamartoma in 1 case). Complication rate of 6.7%, including a small amount of pneumothorax in 2 cases, mild hemoptysis in 1 case, are not required special treatment. Conclusion CT-guided percutaneous lung biopsy is simple, safe, accurate, and has few complications. It can be used as a routine diagnostic tool for pulmonary nodules.
