A Multicenter, Prospective, Randomized Study on Endosonographic Evaluation of Pancreatic Cystic Lesions Using 22 G, 19 G, and Flexible 19 G Fine Needle Aspiration


Jacksonville, Fla., Phoenix/Scottsdale, Ariz.

Trial status:

Open for Enrollment

Why is this study being done?

To document impact of EUS-FNA needle size and flexibility on effectiveness of pancreatic cystic lesions (PCL) aspiration, on ability to obtain sufficient material for standard diagnostic testing, and on diagnostic accuracy of EUS-FNA aspirate for differentiation of mucinous (pre-malignant) and non-mucinous cysts.

Who is eligible to participate?

Inclusion Criteria: - Pancreatic cystic lesion measuring 13mm or greater in largest diameter. - Indicated for EUS evaluation of the PCL including EUS-FNA. - Age 18 years of age or older. - Willing and able to comply with the study procedures and provide written informed consent form to participate in the study. Exclusion Criteria: - Cysts in which FNA is not indicated based on review by the clinician, including potential concern of blood vessel location relative to the cyst. - Requirement for anticoagulation using clopidogril, warfarin, or other long acting antiplatelet agents (with the exception of aspirin) that cannot be safely stopped according to institutional guidelines. - Standard contraindications for EUS. - Known pancreatic pseudocyst. - Pregnancy.
