- W2043453520 abstract "To determine the yield of endobronchial biopsy (EBB) for suspected sarcoidosis, and to evaluate if EBB increases the diagnostic value of fiberoptic bronchoscopy (FOB) when added to transbronchial biopsy (TBB).Prospective study of consecutive patients.Pulmonary clinic of a tertiary-care, academic medical center.Patients consecutively referred for suspected pulmonary sarcoidosis.All patients having FOB performed underwent an evaluation that included history, physical examination, a chest radiograph, and spirometry. During FOB, airway appearance was recorded and both TBB and EBB were performed in a standardized fashion. Six TBB specimens were obtained, as were six EBB samples. For patients with abnormal-appearing airways, four specimens were obtained from the abnormal-appearing airways and two specimens were obtained from the main carina. In patients with normal-appearing airways, four specimens were obtained from a secondary carina and two specimens were obtained from the main carina. A biopsy finding was considered positive if it demonstrated nonnecrotizing granulomas with special stains that were negative for fungal and mycobacterial organisms.The study cohort included 34 subjects (mean +/- SD age, 37.9 +/- 6.8 years; 58.8% were male; 64.7% were African American). EBB findings were positive in 61.8% of patients, while TBB showed nonnecrotizing granulomas in 58.8% of subjects. The addition of EBB increased the yield of FOB by 20.6%. Although EBB findings were more frequently positive in abnormal-appearing airways (p = 0.014), EBB provided diagnostic tissue in 30.0% of patients with normal-appearing endobronchial mucosa. There were no complications resulting from the addition of EBB to TBB.Endobronchial involvement is common in sarcoidosis. EBB has a yield comparable to TBB and can safely increase the diagnostic value of FOB. Pulmonologists should consider routinely performing EBB in cases of suspected sarcoidosis." @default.
