Diagnostic ability of a 22G Franseen needle in endoscopic ultrasound‑guided fine needle aspiration of subepithelial lesions

The differential diagnosis of gastrointestinal subepithelial lesions (SELs) such as gastrointestinal stromal tumors from other benign tumors is important. In the present study, adequate sample rates of endoscopic ultrasound‑guided fine needle aspiration (EUS‑FNA) with a 22G Franseen needle for SELs were evaluated. The present study included 57 consecutive lesions (61 sessions) of EUS‑FNA using a 22G needle to evaluate SELs between July 2013 and...
