Endobronchial biopsy is performed during bronchoscopy and increases the yield of the procedure. In a study of 34 subjects, endobronchial biopsy findings were positive in 61.8% of patients with a yield comparable to transbronchial biopsy, which showed nonnecrotizing granulomas in 58.8% of subjects. The addition of endobronchial biopsy increased the yield of fiberoptic bronchoscopy by 20.6%. [54]
