There are no widely accepted standards for the diagnosis of sarcoidosis. The aim of this study was to assess the relative diagnostic yield of endobronchial ultrasound
fine-needle aspiration (EBUS‑FNA)
and endoscopic ultrasound fine-needle aspiration (EUS‑FNA),
and to
compare them with standard diagnostic techniques such as endobronchial biopsy (EBB), transbronchial
lung biopsy (TBLB), transbronchial needle aspiration (TBNA), and mediastinoscopy. This was a prospective randomized study including consecutive patients with
clinical diagnosis of stage I or II sarcoidosis. EBB, TBLB, and TBNA were performed at baseline in all
patients. Subsequently, patients were randomized to group A (EBUS‑FNA)
or group B (EUS‑FNA).
Next,
a crossover control test was performed: all patients with negative results in group A underwent EUS‑FNA
and all patients with negative results in group B underwent EBUS‑FNA.
If sarcoidosis was not confirmed,
mediastinoscopy was performed. We enrolled 106 patients, of whom 100 were available for the final analysis. The overall
sensitivity and accuracy of standard endoscopic methods were 64% each. When analyzing each of
the standard endoscopic methods separately, the diagnosis was confirmed with EBB in 12 patients
(12%), with TBLB in 42 patients (42%), and with TBNA in 44 patients (44%). The sensitivity and accuracy
of each endosonographic technique were significantly higher than those of EBB+TBLB+TBNA
(P = 0.0112 vs P = 0.0134). The sensitivity and accuracy of EBUS‑FNA
and EUS‑FNA
are significantly higher than
those of standard endoscopic methods. Moreover, the sensitivity and accuracy of EUS‑FNA
tend to be
higher than those of EBUS‑FNA.
