Objective To evaluation the Diagnosis value of single and consociation to drawing materials methods with bronchofibroscopy in pulmonary carcinoma.Methods 481 diagnosed patients with pulmonary carcinoma by bronchofibroscopy during July 2000 to July 2006 were analyzed.Four different drawing materials method including clamping,brushing,needling and rinse checking were used to diagnose.The positive rates of these four methods were compared with single and consociation to drawing materials methods.Results The positive rate of clamping,brushing,needling and rinse checking were 83.9%,70%,59.1%and 35.9%respectively,and the total positive rate was 90.2%after being united.Conclusions Bronchofibroscopy is one of the most important methods in diagnosing pulmonary carcinoma. Using multiple drawing materials methods in bronchofibroscopy can improve the accuracy rate of diagnosis of lung cancer significantly.
