Diagnostic yield of endobronchial ultrasound-guided transbronchial needle aspiration for suspected sarcoidosis, before and after the research cytopathology review
| Initial diagnostic yield | Diagnostic yield following the cytopathology review | |
|---|---|---|
| Per procedure (N=45) | ||
| Overall diagnostic yield | 34/45 (75.6) | 36/45 (80) |
| Diagnosis from cell block only, where available (N=42) | 14/42 (33.3) | 14/42 (33.3) |
| Diagnosis from slides and cell block, where available (N=42) | 19/42 (4.5) | 19/42 (4.5) |
| Diagnosis from slides alone (slides available in all 45 patients) | 1/45 (2.2) | 3/45 (6.7) |
| Per lymph node (N=115) | ||
| Overall diagnostic yield | 68/115 (59.1) | 73/115 (63.5) |
| Diagnosis from cell block only, where available (N=89) | 37/89 (41.6) | 37/89 (41.6) |
