BACKGROUND: The utility of transbronchial needle aspiration (TBNA) in visible endobronchial lesions presenting as either an exophytic mass lesion (EML) or submucosal and peribronchial disease (SPD) is not well established. OBJECTIVE: To compare the yield of conventional diagnostic procedures (CDP) (bronchial washing, bronchial brushing, and endobronchial forceps biopsy) with that obtained from a combination of CDP and TBNA (CDP + TBNA). DESIGN: Prospective study of 55 patients. SETTING: Tertiary-care referral hospital. RESULTS: Of the 55 patients in whom malignancy was confirmed, CDP + TBNA identified 53 (96%) vs 42 (76%) identified by CDP (p = 0.001). The highest yield from any individual procedure was obtained by TBNA. Of the 23 patients with SPD, 22 (96%) were diagnosed using CDP + TBNA compared with 15 (65%) by CDP (p = 0.016); the yield from TBNA alone (22 of 23) in this group surpassed the combined yield from all other procedures. Although no statistically significant difference in yield was observed for EML, the use of TBNA identified four additional patients compared with CDP. CONCLUSION: We conclude that the addition of TBNA to CDP increases diagnostic yield in patients with visible endobronchial lesions.
