Abstract
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.关键词
