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.
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.

| wet suction | Procedure | Before pucturing the lesion, the stylet was removed and the needle was pre-flushed with 1-2 mL of saline using a 10-mL syringe, the endoscopist then punctured the lesion and replaced the 10-mL syringe with a 10-mL pre-vacuum syringe |
| Measure | Description | Time Frame |
|---|---|---|
| diagnostic sensitivity of WS technique and SNP technique by EUS-FNB | Sensitivity will be calculated as the probability of actually having pancreatic diasease and being diagnosed by WS technique during EUS-FNB | 6 month |
| diagnostic specificity of WS technique and SNP technique by EUS-FNB | specificity will be calculated as the probability of actually not having the pancreatic disease and being diagnosed as being free of the disease by WS or SNP technique during EUS-FNB | 6 month |
| Measure | Description | Time Frame |
|---|---|---|
| Sample adequacy of WS technique and SNP technique by EUS-FNB | The tissue integrity assessments of specimens will be evaluated by score 0-3. Score 3, sufficient material for adequate histological interpretation; Score 2, samples allowing limited histological assessment; Score 1,samples not providing histological information. | 6 month |

| standard negative pressure suction | Procedure | after puncturing the lesion, the endoscopist removed the stylet and attached a 10-mL pre-vacuum syringe for aspiration. |
|
| Cell density of WS technique and SNP technique by EUS-FNB |
The Cell density assessments of specimens will be evaluated by score A-C. Score A：Satisfactory, more than 4 clusters of cells, each cluster more than 10 cells. Score B：Sufficient, approximately 2-4 clusters, each with more than 10 cells Score C: ：Unsatisfactory, less than 2 clusters or no cells on slide |
