Abstract
Objective To investigate and analyze the clinical application of auto-fluorescence bronchoscopy (AFB). Methods 224 patients(M/F= 190/34)performed bronchoscopy were selected and randomly divided into the control group(n= 112,M/F= 96/16)and observation group(n= 112,M/F= 94/18).Patients of control group were performed white light bronchoscopy(WLB).Patients of observation group were performed WLB combined AFB.The primary endpoint was masculine rate of pathology biopsy and bleeding after biopsy.The retrospective analysis was performed. Results The masculine rate of carcinoma in situ of the observation group was 3.1%,which of the control group was 1.0%,the difference was statistically significant(χ2= 19.761,P 0.05). Conclusion AFB can improve site-specific accuracy of doubtful focus,improve masculine rate of pathology biopsy,and lessen bleeding after biopsy. Key words: Bronchoscopy/methods; Fluorescence; Biopsy; Diagnosis
