Su1353 Diagnostic Accuracy of Combined Needle Use of the New 20G Procore Fnb and the 25G Fna Needle in Solid Gi-Lesions

EUS Fine Needle Biopsy (FNB) needles were designed to improve histologic yield, while maintaining the flexibility to permit ease of use. However, the diagnostic benefit of EUS-FNB needles as compared to the conventional fine needle aspiration (FNA) needles remains unclear. This study aimed to identify the diagnostic accuracy of combined needle use of a new 20G ProCore FNB needle and the 25G FNA needle.
