The GRANULOMA Randomized Clinical Trial
Granuloma was a randomised controlled study of endobronchial or endoscopic ultrasound (EUS or EBUS) for sampling mediastinal lymph nodes compared to TBBX in patients with Stage I or II sarcoidosis. The results demonstrated that endosonography (EUS or EBUS) is more superior and safer to conventional transbronchial lung biopsy.
