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.

|---|---|
|
Eksperimentel: Standard suction
These are patients who will have endoscopic ultrasound-guided fine needle aspiration using the standard suction FNA technique: 15 to-and-fro movements within the lesion will be performed with use of 10cc suction syringe.

Eksperimentel: Capillary suction
These are patients who will have endoscopic ultrasound-guided fine needle aspiration using the capillary suction FNA technique: 15 to-and-fro movements within the lesion will be performed with simultaneous minimal negative pressure provided by pulling the needle stylet slowly and continuously.
