目的：分析CT引导下PCNB（经皮肺穿刺活检）在肺占位病变诊断中的应用

Objective: To analyze PCNB (percutaneous needle biopsy) value in the diagnosis of lung occupying CT-guided. Methods: The hospital in March 2017 ~ lung space occupying lesions row in June 2019 admitted to the study, all patients are in line PCNB CT-guided preoperative diagnosis, drawn a record of success, the success rate of the final drawn, diagnosis typing accuracy and diagnostic accuracy, the rate of complications occur. Results: The 40 patients disposable diagnostic coverage success rate was 87.5% (35 patients), the final drawn 100% success rate (40), 36 cases of diagnosis, diagnostic accuracy was 90.00%, malignant lesion detection was 88.24% (containing 80.00% of lung squamous cell carcinoma, lung adenocarcinoma 100%, colorectal cancer 85.71%, 90.91% small cell lung carcinoma, large cell undifferentiated carcinoma 80.33%), the detection rate of 100.00% benign lesions (including lung abscess 100.00%, 100.00% ball tuberculosis, pneumoconiosis 100.00%), the adverse reactions was 12.50% (containing 5.00% pneumothorax, needle tract bleeding 2.50%, 2.50% pulmonary compressed air thrombosis 2.50%). Conclusion: CT guided PCNB diagnosis of non-occupying lesions can significantly improve the success rate of the drawn diagnostic accuracy, while effectively reduce the incidence of complications.

Objective: To analyze the application value of PCNB (psoriasis biopsy) in the diagnosis of pulmonary occupancy lesions under CT guidance. Methods: The patients treated in our hospital from March 2017 to June 2019 as the object of study, all patients with CT-guided PCNB diagnosis, record a material success rate, final material success rate, diagnostic accuracy and type-type diagnosis accuracy, complication incidence. Results: The success rate of 40 patients in this diagnosis was 87.5% (35 cases), the final yield was 100% (40 cases), 36 cases were clearly diagnosed, the diagnostic accuracy rate was 90.00%, of which the detection rate of malignant lesions was 88.24% (including lung squamous cancer 80.00%, lung adenocarcinoma 100%, lung adenocarcinoma 100%, lung adenocarcinoma) Rectal cancer 85.71%, lung small cell carcinoma 90.91%, large cell undifferentiated cancer 80.33%), benign lesiondetection rate of 100.00% (including pulmonary abscess 100.00%, tuberculosis ball 100.00%, dust lung 100.00%), adverse reaction rate of 12.50% in this group (including gas chest 5.00%, needle bleeding 2.50%, pulmonary compression 2.50%, air thrombosis 2.50%). Conclusion: Using CT to guide PCNB to diagnose non-occupancy lesions can significantly improve the success rate and diagnostic accuracy of materials, and effectively reduce the occurrence of complications.

Objective: to analyze the value of CT guided PCNB in the diagnosis of lung space occupying lesions. Methods: the patients with lung lesions in our hospital from March 2017 to June 2019 were studied. All patients were diagnosed by PCNB guided by CT. The success rate of one-time sampling, the success rate of final sampling, the accuracy rate of diagnosis and classification, and the incidence rate of complications were recorded. Results: the successful rate of one-time sampling was 87.5% (35 cases), the final successful rate of sampling was 100% (40 cases), and the accurate rate of diagnosis was 90.00% (36 cases). The detection rate of malignant lesions was 88.24% (including 80.00% of squamous cell carcinoma, 100% of adenocarcinoma, 85.71% of rectal cancer, 90.91% of small cell carcinoma and 80.33% of undifferentiated large cell carcinoma). The detection rate of benign lesions was 100% The adverse reactions were 12.50% (including 5.00% of pneumothorax, 2.50% of needle hemorrhage, 2.50% of pulmonary compression and 2.50% of air thrombus). Conclusion: using CT guided PCNB in the diagnosis of non occupying lesions can significantly improve the success rate and diagnostic accuracy, and effectively reduce the incidence of complications.<br>
