Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

There are many factors that can affect the diagnostic yield of EUS-FNA, including lesion factors, the endoscoist experience, the needle size, the number of needle passes, and the suction technique. since diagnostic efficacy of different suction techniques for EUS-FNB is still uncertain, thus we decided to compare the diagnostic efficacy of three common methods: the 10 ml standard negative pressure, slow pull and wet suction.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

the standard suction: after the needle is inserted in the mass, removing the stylet before performing EUS-FNA. Then attach a 10mL syringe to the end of needle. 20 times of for-backward Suction was applied after the lesion was punctured.

slow-pull : after the needle is inserted in the mass, slowly pull the stylet out while performing EUS-FNA with 20 times for-backward.

wet suction: after removing the stylet, the needle was flushed with 5mL of saline solution to replace the column of air with saline. A 10mL syringe was attached to the end of the needle. 20 times of for-backward Suction was applied after the lesion was punctured.
