Objective To evaluate the value and safety of CT-guided transthoracic cutting needle lung biopsy in the diagnosis of pulmonary flake or consolidation lesions.Methods A total of 100 patients admitted in the department of respiration,PLA Army General Hospital from January 2013 to December 2016 underwent CT-guided transthoracic cutting needle lung biopsy.Clinical data,chest CT images,pathological results and complication of the patients were retrospectively analyzed.Results One hundred patients(64 males and 36 females,aged 15-85 years;mean 56.3 ± 12.1 years old) showed single (≥ 2.5 cm × 2.5 cm in vertical diameter) or multiple (at least one lesion≥2.5 cm × 2.5 cm in vertical diameter) flake or consolidation lesions in chest CT scan.Lung biopsy was successful in 96 of 102 cases(94.1%).Among 83 patients pathologically diagnosed by lung biopsy,82 patients were finally confirmed the diagnosis.The diagnostic accuracy was 86.5% (83/96) and the correct diagnosis rate was 82.0% (82/100).Complication of transthoracic lung biopsy had pneumothorax(4.9%,5/102),hemoptysis(11.8%,12/102) and chest pain(4.9%,5/102).In 82 patients confirmed diagnosis,tumor accounted for 34.1% (28 patients),including lung adenocarcinoma (78.4%,22/28),squamous cell carcinoma(14.3%,4/28),small cell lung carcinoma(3.5%,1/28) and pleural mesothelioma (3.5%,1/28),while non-neoplastic lesions accounted for 65.9% (54 patients),including organizing pneumonia (42.6%,23/54),nonspecific inflammation (24.1%,13/54),pulmonary tuberculosis (16.7 %,9/54),purulent pneumonia (7.4 %,4/54),cryptococcal pneumonia (3.7 %,2/54) and allergic pneumonial,nonspecific interstitial pneumonia and desquamative interstitial pneumonia (1 case respectively,1.9%).Conclusion The CT-guided transthoracic cutting needle lung biopsy is a safe technique with a high diagnostic value and low complication for single or multiple flake or/and consolidation lesions.Transthoracic lung biopsy is actively performed for undetermined pulmonary flake or consolidation lesions.%目的 评价CT引导下切割针经皮活检对肺部片状、实变病灶的诊断价值及安全性. 方法 回顾性分析我院2013-01~2016-12 CT引导下切割针经皮肺活检肺部单发或多发性片状、实变病灶患者100例的102例次活检的临床、影像及病理资料. 结果 100例患者,男64例,女36例,年龄在15-85岁,平均(56.3±12.1)岁.患者肺部单发片状、实变病灶均≥2.5 cm ×2.5 cm,多发性片状病灶具有≥2.5 cm ×2.5 cm的可穿刺病灶.96例穿刺成功,肺活检穿刺成功率94.1%(96/102).获得病理诊断83例,82例明确诊断,诊断的准确率86.5% (83/96),正确诊断率82.0% (82/100).肺活检气胸发生率4.9% (5/102),咯血11.8% (12/102),胸痛4.9%(5/102).82例确诊患者中,肿瘤28例(34.1%),其中肺腺癌22例(78.6%),肺鳞癌4例(14.3%),小细胞肺癌及胸膜间皮瘤各1例(3.5%);非肿瘤病变54例(65.9%),其中机化性肺炎23例(42.6%),非特性炎症13例(24.1%),肺结核病9例(16.7%),化脓性肺炎4例(7.4%),隐球菌肺炎2例(3.7%),过敏性肺炎、非特异性间质性肺炎、脱屑性间质性肺炎各1例(1.9%). 结论 CT引导下切割针经皮肺活检对肺部单发或多发性片状、实变病灶具有较高的诊断价值,不良反应少,是安全的方法.对性质不明确的肺部片状、实变病灶,积极行经皮肺活检明确诊断.
