The Comparison of Wet Suction and Dry Suction Technique in EUS-FNA for the Outcomes in Pancreatic Solid Lesions

"For the wet suction technique, after removing the stylet, the needle was flushed with 2 mL of saline solution to replace the column of air with saline solution. A 10-mL suction syringe, loaded to 5ml negative pressure, was attached in a locked position to the needle after flushing the needle with saline solution. The needle is moved back and forth 20-30 times by applying negative pressure suction within the lesion. Afterwards, the needle is withdrawn from the lesion."

"For the dry suction technique, after locating by EUS, the stylet was removed from the needle before performing FNA. A 10-mL syringe, loaded to 5ml negative pressure, was attached in a locked position to the needle. Suction was applied after the lesion was punctured. The needle is moved back and forth 20-30 times by applying negative pressure suction within the lesion. Afterwards, the needle is withdrawn from the lesion."
