A Multi-center, Prospective, Single-blind, Controlled Trial Comparing Diagnostic Value of Different EUS-FNA Techniques (EUS-FNA)

September 14, 2018 updated by: Shanghai Zhongshan Hospital

A Multi-center, Prospective, Single-blind, Controlled Trial Comparing Suction Technique, Slow-pull Method and Wet Suction Technique on Specimen Quality and Diagnostic Accuracy in Endoscopic Ultrasound-guided Fine-needle Aspiration

The aim of this study is to compare endoscopic ultrasound guided-fine needle aspiration (EUS-FNA) with a standard 22-gauge needle using "standard suction", "slow-pull" and "wet suction" for thoracic/abdominal solid/solid-cystic lesions. Investigators intend to compare the effectiveness and safety of the three methods in order to discover the optimized technique for obtaining diagnostic material and making accurate diagnosis.
