Study Description

Brief Summary: The purpose of this study is to compare the diagnosis accuracy between of wet suction (WS) technique and standard negative pressure (SNP) technique in EUS-FNB by 22G EUS Procore fine needle biopsy（FNB）device for solid pancreatic lesions.

Detailed Description: This is a multi-center, single-blind, randomized, controlled trial. two hundred and ninety six patients with solid pancreatic lesions referred for EUS guided fine needle biopsy will be randomly assigned to two groups. For group A which will be used with 22G EUS Procore fine needle biopsy device, the pass sequence is WS-SNP-WS-SNP technique. For group B with 22G EUS Procore fine needle biopsy device, the pass sequence is SNP-WS-SNP-WS. All procedures will be performed by experienced echo-endoscopists, and the patients and assessors (cytologists and pathologists) will be blinded during the entire study. The primary outcome measure is the diagnosis yield. Secondary outcome measures are specimen quality.
