The research for no X-ray perspective by bronchoscopic lung biopsy in the diagnosis of peripheral lung cancer

Objective To investigate the transbronchial lung biopsy of peripheral lung cancer diagnostic role.Methods From January 2011 to December 2011,the clinical manifestations,X-ray and CT examination of suspected peripheral lung cancer,and the bronchoscopy was not found 50 cases of bronchial sub-segment of the proximal cavity lesions.Passing a fiberoptic bronchoscope(bronchoscopy) lung biopsy(TBLB) surgery.Results The diagnostic transbronchial lung biopsy confirmed 15 cases,the positive rate was 30%(15/50).Show the different size of the lesion of peripheral lung cancer based on CT,bronchoscopic biopsy positive rate of diagnosis,the difference was significant(P 0.05).The male patients' TBLB positive rate was significantly higher than women,,eight cases adenocarcinoma,four cases of squamous cell carcinoma,two cases of large cell carcinoma,one case of small cell carcinoma,adenocarcinoma was significantly higher than the carcinoma group(P 0.05).Which close to the lungs and hilar were 12 cases,the TBLB positive biopsy rate was significantly higher than the near pulmonary takeaway and chest group,the difference was significant(P 0.05).Conclusion Transbronchial lung biopsy operation on patients with peripheral lung cancer is easy and safe,for multiple purposes,is the only way to diagnose and correct positioning of the reliable inspection methods,can improve the diagnosis of peripheral lung cancer rate.
