目的 :对痰细胞学及纤维支气管镜检查不能确诊的肺外周病灶 ,在 CT引导下经皮肺活检 ,以期术前定性诊断 ,发现早期肺癌。方法 :收集痰检及纤维支气管镜检不能确诊的肺外周病灶 6 4例 ,应用 CT机薄层扫描定位 ,普通腰穿针及 Gallini活检枪经皮穿刺 ,行细胞学和组织学检查 ,以术后病理诊断及临床观察结果为判定标准 ,分别统计细胞学和组织学诊断的准确性。结果 :恶性病变 38例 ,良性病变 2 6例。细胞学诊断的敏感性 75 .0 % (18/ 2 4 ) ,特异性 10 0 % (8/ 8) ,准确性 81.3% (2 6 / 38) ;组织学诊断的敏感性 93.3% (2 8/ 30 ) ,特异性 10 0 % (18/ 18) ,准确性 95 .8%(46 / 4 8)。结论 :CT引导经皮肺穿刺安全、准确、诊断迅速 ,Gallini活检枪穿刺的敏感性和准确性均优于细针穿刺
OBJECTIVE: Percutaneous lung biopsy under CT-guided sputum cytology and fiberoptic bronchoscopy can not confirm the diagnosis of peripheral lung lesions in order to preoperative qualitative diagnosis and early lung cancer. Methods: Totally 64 cases of peripheral pulmonary lesions were collected by sputum examination and fiberoptic bronchoscopy. CT scanning, thin-section CT, Gallini biopsy gun and percutaneous puncture were performed. Cytology and histology were performed. Post-pathological diagnosis and clinical observation of the results as a criterion, respectively, statistics cytology and histological diagnosis accuracy. Results: There were 38 malignant lesions and 26 benign lesions. The cytological diagnostic sensitivity was 75.0% (18/24), specificity was 10% (8/8), and the accuracy was 81.3% (26/38). The sensitivity of histological diagnosis was 93.3% (2 8) / 30), specificity 10 0% (18/18), accuracy 95.8% (46/48). Conclusion: CT guided percutaneous pulmonary puncture is safe, accurate and rapid diagnosis. The sensitivity and accuracy of Gallini biopsy gun are superior to those of fine needle aspiration
