Different Suction Techniques For Endoscopic Ultrasound-Guided Fine-Needle Biopsy In Pancreatic Solid Lesions

During endosonographic examination, the pancreatic mass was evaluated with color Doppler to avoid the involvement of vessels. The needle (20 Gauge, EchoTip ProCore 20G with ReCoil Stylet™, Cook Medical, Bloomington, IN, USA) was sharpened by withdrawing the stylet approximately 2 mm, and then was advanced into the lesion: 15 to-and-fro movements within the lesion were performed, with simultaneous minimal negative pressure provided by pulling the needle stylet slowly and continuously.
