Diagnosis of lung nodules with peripheral/radial endobronchial ultrasound-guided transbronchial biopsy.
: Pulmonary nodules are frequently encountered in clinical practice, but diagnostic sensitivity of traditional bronchoscopy remains less than desirable. Transbronchial biopsy (TBBX) under fluoroscopic guidance with flexible bronchoscopy has a sensitivity of 34% for lesions <20 mm and 63% for lesions >20 mm. Navigational technologies such as electromagnetic navigation bronchoscopy have increased the yields of TBBX to approximately 73%. We examine the sensitivity and factors that may impact the diagnostic yield of a similar technology, namely, radial endobronchial ultrasound (EBUS). ⋯ : Lesion size, distance, presence of a computerized tomography bronchus sign, or lobar location may not impact the diagnostic yield of bronchoscopic biopsy of peripheral lung nodules with radial EBUS navigation.
