Brief Summary
The primary aim of this study is to compare the tissue specimen quality and diagnostic accuracy of biopsies obtained with one puncture of a regular 22 FNB G needle and the motorized EUS CNB device of pancreatic lesions. The secondary aims are to compare the rate of blood contamination in the specimens obtained from biopsies of pancreatic lesions and the overall procedure duration. The hypothesis of this study is that the proportion of cases in which a single puncture of the lesion in question delivers adequate diagnostic tissue is higher with the motorized EUS CNB than with the 22 G FNB.

Outcome Measures
Primary Outcomes (1)
Diagnostic specimen
The percentage of cases achieving an adequate diagnostic yield (defined as a cellularity score of ≥2) after a single needle pass with either the EndoDrill or the 22-G FNB device
during study intervention
Secondary Outcomes (3)
Blood contamination of the specimen
during study intervention
cellularity score

Procedure Duration
during study intervention
Study Arms (2)
EUS-FNB
ACTIVE COMPARATORThis arm will undergo biopsy via the standard of care, which involves EUS-guided biopsy using the 22-gauge FNB needles
EUS-CNB
EXPERIMENTALThis arm will undergo biopsy with the novel EUS-CNB device
Interventions
The EUS-CBD (Endodrill, Bibb Medical, Lund Sweden) differs from currently available needles (FNB) in that it obtains tissue by drilling into target lesions rather than puncturing them.
Eligibility Criteria
You may qualify if:
- Patients who require EUS and tissue sampling of pancreatic solid lesions (size\> 2.5 cm)
- Patients who can give consent
You may not qualify if:
- patients without pancreatic lesions
- Pregnant females
- Hematologic and Coagulation disorders (platelets \< 50,000/mm3, INR \> 2, ANC \<1000)
- Patients with acute pancreatitis in the immediate 2 weeks before the procedure (if the lesion to be biopsied is in the pancreas)
- Cardiorespiratory dysfunction that precludes sedation
- patients unable to provide informed consent
- Previous chemotherapy or radiotherapy for a pancreatic neoplasm
- Patients who are not candidates for emergency surgery in case complications arise from the biopsy
