Endobronchial ultrasound plus fluoroscopy versus fluoroscopy-guided bronchoscopy: a comparison of diagnostic yields in peripheral pulmonary lesions.

Background: Even though fluoroscopy-guided bronchoscopy has been well developed, the diagnostic yield of peripheral pulmonary lesions (PPLs) remains unsatisfying. Therefore, endobronchial ultrasound (EBUS) has been implemented recently to enhance the possibility of attaining true diagnosis. However, there are few studies that directly compare the success rate of fiber-optic bronchoscopy with fluoroscopic guidance to that of EBUS guidance in the diagnosis of PPLs in the same institute and in the same study period.
