Diagnostic ability of EUS-FNA for SELs compared with Franseen and conventional needles (n = 111).
| Needle | ||||
|---|---|---|---|---|
| Total | Franseen | Conventional | ||
| Cases (n) | n = 111 | n = 36 | n = 84 | p-Value |
| Sensitivity | 96.4% (81/84) | 100% (29/29) | 94.5% (52/55) | 0.548 |
| Specificity | 96.3% (26/27) | 100% (7/7) | 95.0% (19/20) | 1.000 |
| PPV | 98.8% (81/82) | 100% (29/29) | 98.1% (52/53) | 1.000 |
| NPV | 89.7% (26/29) | 100% (7/7) | 86.4% (19/22) | 0.557 |
| Accuracy | 96.4% (107/111) | 100% (36/36) | 94.7% (71/75) | 0.302 |
EUS-FNA, endoscopic ultrasound-guided fine needle aspiration; SELs, subepithelial lesions; PPV, positive predictive value; NPV, negative predictive value.
