Comparison of Two Needle Aspiration Techniques for Endoscopic Ultrasound-guided Fine Needle Aspiration (EUS-FNA) in Solid Pancreatic Lesions

Comparison of Two Needle Aspiration Techniques for Endoscopic Ultrasound-guided

The aim of this study is to compare Endoscopic Ultrasound and Fine Needle Aspirate with a standard 22-gauge needle using either "standard-suction" or "capillary suction" methods for solid pancreatic lesions. Investigators hope to discover the best technique for obtaining diagnostic material when patients with a pancreatic mass undergo endoscopic ultrasound and fine needle aspirate procedure.

There are currently several techniques for obtaining tissue during endoscopic ultrasound and fine needle aspirate. The procedure will be performed by either the capillary suction technique or no suction technique.

Inclusion Criteria:

- In-patients and out-patients between the age of 18years and 90 years with pancreatic masses presenting for EUS-FNA

Exclusion Criteria:

• Uncorrectable coagulopathy (INR > 1.5)
• Uncorrectable thrombocytopenia (platelet < 50,000)
• Uncooperative patients
• Pregnant women (women of childbearing age will undergo urine pregnancy testing, which is routine for all endoscopic procedures)
• Refusal to consent form
• Cystic lesions
• Inaccessible lesions to EUS
