About this study
Official title: Comparing the Sample Quality of 22G Trident Needle Combined With Different Aspiration Techniques in EUS-Guided Fine-Needle Biopsy of Pancreatic Solid Lesions: A Randomized Controlled Multicenter Clinical Study
The goal of this clinical study is to compare the tissue adequacy, cellularity, blood contamination, accuracy, sensitivity, specificity of the 22G Trident needle combined with three different aspiration techniques (dry-suction, wet-suction, and slow-pull) in Endoscopic ultrasound-guided fine-needle biopsy for solid pancreatic lesions.
Read the detailed description
Patients who met the inclusion criteria of this trial and did not meet the exclusion criteria were randomly divided into six groups according to the crossover grouping design. Samples were collected using a 22G Trident needle in different suction sequences. The advantages and disadvantages of different suction techniques in terms of sample quality and diagnostic efficacy were compared to further clarify the optimal suction sampling scheme for Endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB) using a 22G Trident needle.

What is being measured
The primary outcome is the main question the study is designed to answer.
Tissue adequacy
Grade A, existing core tissue (defined as structurally intact tissue with a long axis length of at least 550 μm) that clearly characterizes the lesion and is sufficient for diagnosis; Grade B, the presence of core fragments that do not meet the histological criteria for structural integrity, but can still be diagnosed based on cell morphology; Grade C, no diseased tissue is found and no diagnosis can be made based on the sample.
Measured: 2 months
Secondary outcomes (5)
Cellularity
Grade A: Satisfactory, with more than 4 clusters, each containing at least 10 cells for cytological analysis; Grade B: Adequate, with 2-4 clusters, each containing at least 10 cells for cytological analysis; Grade C: Insufficient, with<2 clusters suitable for cytological analysis or non-representative samples, or<50 cells with clear nuclear structures.
Measured: 2 months
Blood contamination
The histological blood contamination score is assessed by grading the percentage of red blood cells in the entire 40x magnified field of view. Grade A: Red blood cells are present in<25%of the slides; Grade B: Red blood cells occupy 25%-50%of the slide; Grade C: Red blood cells are present in>50%of the slides; Grade D: No tissue.
Measured: 2 months
Diagnostic accuracy
Diagnostic accuracy was calculated as the proportion of true positive and true negative in all evaluated cases.
Measured: 6 months
Diagnostic sensitivity
Diagnostic sensitivity was calculated as the proportion of true positives in patient cases.
Measured: 6 months
Diagnostic specificity
Diagnostic specificity was calculated as proportion of true negative in healthy cases.
Measured: 6 months

What does the primary outcome measure?
Tissue adequacy (time frame: 2 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Jun 2025.
