Diagnostic value of lung biopsy by electronic bronchoscope in peripheral lung cancer

Objective To investigate the diagnostic value of lung biopsy under electronic bronchoscope in peripheral lung cancer. Methods There were 53 patents with suspected peripheral lung cancer by chest X-ray and CT, which couldn′t be observed by bronchoscopy set. Lung biopsy was performed under electronic bronchoscopy set to skeptical focus. Results Among the 53 patients, 37 cases (69.8%) were identified as peripheral lung cancer, including 23 cases of adenocarcinoma, 10 cases of small cell undiferentiated carcinoma. 7 cases were identified as optimum, including 3 cases of nonspecific inflammation and 4 cases of tuberculosis. There were also 9 cases being false negative. The total final diagnosis rate was 83.0%. Conclusion Lung biopsy of under electronic bronchoscope is a better method, which can significantly improve positive rate of peripheral lung cancer. It is safe and feasible with few complications.
