Summary

EUS-guided fine needle aspiration (EUS-FNA) is a safe and effective method for diagnosing pancreatic and peripancreatic solid masses. The aim of this study is to compare the two aspiration methods in EUS-FNA: negative-pressure suction with syringe vs. capillary sampling with stylet slow-pull technique. We will evaluate the diagnostic adequacy and accuracy of the specimens obtained by EUS-FNA with two aspiration methods.

Conditions

  • EUS-FNA
  • Cytodiagnosis

Interventions

PROCEDURE

EUS-FNA

EUS-guided fine needle aspiration will be performed by a single experienced endoscopist (D.H.P) using a conventional linear array echoendoscope (GF-UCT240, Olympus Optical Tokyo, Japan) under conscious sedation with midazolam and meperidine. After the optimal puncture site was determined, a puncture will be done using a 22-gauge EchoTip needle (Cook Endoscopy, Winston-Salem, NC) guided by real-time EUS imaging. Subsequently, the stylet will be slowly removed as the needle is moved to-and-fro for 15 times (capillary sampling method with stylet slow-pull technique) or negative-pressure 10 mL syringe will be applied (negative-pressure syringe suction). A total of 4 needle passes will be done for the lesion with using above two aspiration methods alternatively.
