Summary

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.

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.
