Oki et al. [1] demonstrate the potential utility of transoesophageal bronchoscopic ultrasound-guided fine-needle aspiration (EUS-B-FNA) as an alternative to endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and other bronchoscopic techniques (especially transbronchial biopsy, TBB) in stage 1-2 sarcoidosis. We and others [2-4] have also supported the use of this technique in mediastinal tuberculosis and lung cancer (and by inference sarcoidosis too). Whilst supporting this technique and congratulating Oki et al. on their results, we suggest a note of caution here. We believe that endosonography specialists should consider the most appropriate diagnostic procedure in sarcoidosis specifically.
