Abstract
Objective: T evaluate the diagnostic yield of bronchial washing and bronchial brushing in addition to forceps biopsy for the
pathological diagnosis of lung cancer.
Material and method: A retrospective review of bronchoscopy cases for investigation of lung cancer in Lampang Hospital vetween January 2002 and December 2006 was done. All 820 cases were classified into 3 groups according to bronchoscopic findings (1) endrobronchial mass (2)endobronchial abnomality of abnormal bronchial mucosa and (3) normal bronchial mucosa. Statistical analysis of the data was performed by using the likelihood-ratio chi-square test.
Results: A significant increase in the diagnostic yield for lung cancer was seen when bronchial washing were added
to forceps biopsy only in endrobronchial abnormality group (43.5% VS 50.2%, p=0.01) akd when bronchial brushing were added to forceps biopsy only in endobronchial mass group. (68.4% VS 89.5%, p=0.027)
Conclusion: The addition of bronchial washing or bronchial brushing to forceps biopsy is beneficial when performed only in selected cases.
