Trial for the Diagnosis of Sarcoidosis

This randomized study investigates two different diagnostic strategies for patients with suspected pulmonary sarcoidosis stage I/II. The objective is to assess the role of endosonography (EBUS/ EUS - FNA) in demonstrating non-caseating granulomas in comparison with conventional bronchoscopy (TBLB + EBB). Also the researchers investigate the additional value of BAL, in relation to endosonography and conventional bronchoscopy (TBLB + EBB), in diagnosing sarcoidosis. Thirdly the researchers aim to assess the rate of complications in both the endosonography and conventional bronchoscopic workup.
