詳細な説明
For this prospective single-blinded randomized trial, two 10cc syringes was prepared. Two syringe was provided as same performance. However, one syringe is falsely made as suction syringe (fake one). During EUS-FNA, two syringe is randomly assigned and loaded by a nurse. Thus, operator was blinded which syringe is with suction or without suction.
First hypothesis: There is difference in the diagnostic accuracy of pancreatic masses according to EUS-FNA with suction or without suction/ different number of to-and-fro motion.
Second hypothesis: There is difference in the amount of blood in samples obtained by EUS-FNA with suction or without suction/ different number of to-and-fro motion.

アクティブコンパレータ:EUS-FNA with suction
EUS-FNA with suction/10, 15, 20 to-and-fro motion vs. EUS-FNA with suction/10, 15, 20 to-and-fro motion Visual assessment as stoping rule: 20 to-and-fro motion at different site will be performed when EUS-FNA sampling with 10, 15, 20 to-and-fro motion is unsatisfactory.
