EUS-FNA
Brief summary
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.
Interventions
Patients will be sampled for a total of 3 consecutive FNA passes with a sequential method of standard suction, slow-pull, and wet suction. After completing all the passes, the obtained specimen will be packed individually and sent to pathologists who are blind to the method sequence.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Diagnostic yield of wet suction technique | 1 year | A positive diagnosis of malignancy by an EUS biopsy specimen is accepted as a true positive. A benign diagnosis is confirmed by surgical tissue samples when available or clinical follow-up after 1 year. |
| Diagnostic yield of standard suction technique | 1 year | A positive diagnosis of malignancy by an EUS biopsy specimen is accepted as a true positive. A benign diagnosis is confirmed by surgical tissue samples when available or clinical follow-up after 1 year. |
| Diagnostic yield of slow-pull technique | 1 year | A positive diagnosis of malignancy by an EUS biopsy specimen is accepted as a true positive. A benign diagnosis is confirmed by surgical tissue samples when available or clinical follow-up after 1 year. |
| Specimen quality score of wet suction | Immediate | EUS-FNA obtained specimen is scored as follows: 1) blood contamination: 0 for severe, 1 for moderate, 2 for few; 2) tissue structure: 0 for none, 1 for 1-2 structures seen, 2 for more than 3 structures seen; 3) cell quantity: 0 for \<10/HPF, 1 for \<50/HPF, 2 for \>50/HPF; 4) diagnosability: 0 for hard to diagnose, 1 for suspicious diagnose, 2 for definite diagnosis. |
| Specimen quality score of standard suction | Immediate | EUS-FNA obtained specimen is scored as follows: 1) blood contamination: 0 for severe, 1 for moderate, 2 for few; 2) tissue structure: 0 for none, 1 for 1-2 structures seen, 2 for more than 3 structures seen; 3) cell quantity: 0 for \<10/High power field(HPF), 1 for \<50/HPF, 2 for \>50/HPF; 4) diagnosability: 0 for hard to diagnose, 1 for suspicious diagnose, 2 for definite diagnosis. |
| Specimen quality score of slow-pull | Immediate | EUS-FNA obtained specimen is scored as follows: 1) blood contamination: 0 for severe, 1 for moderate, 2 for few; 2) tissue structure: 0 for none, 1 for 1-2 structures seen, 2 for more than 3 structures seen; 3) cell quantity: 0 for \<10/HPF, 1 for \<50/HPF, 2 for \>50/HPF; 4) diagnosability: 0 for hard to diagnose, 1 for suspicious diagnose, 2 for definite diagnosis. |
