Abstract: Objective To explore the application value of coaxial semi automatic biopsy gun in the biopsy of small pulnonary nodules.Methods A retrospective analysis was performed on 40 patients with small pulmonary nodules who underwent CT guided percutaneous pulmonary nodules biopsy.Taking postoperative pathology diagnosis or imaging follow-up results as gold standard,the accuracy,specificity,sensitivity,intraoperative complications and puncture techniques of biopsy were analyzed.Results All operations were successfully completed.There were 29 malignant lesions and 11 benign lesions confirmed by postoperative pathology diagnosis or imaging follow-up results.The sensitivity,specificity,accuracy rate of puncture biopsy in diagnosis of malignant small pulmonary nodules was 89.65％ (26/29),100％ (11/11),92.50％ (37/40).The main complications were pneumothorax and local hemorrhage.Conclusion Percutaneous biopsy of small pulmonary nodules using coaxial semi-automatic biopsy gun has high accuracy,specificity and sensitivity,is a safe and effective method.
