David Karsenti et al. 22G Acquire vs. 20G Procore needle for endoscopic ultrasound-guided
biopsy of pancreatic masses: a randomized study comparing histologic sample quantity
and diagnostic accuracy
Crossover trial comparing two new endoscopic ultrasound fine-needle biopsy needles
in 60 patients with pancreatic masses. It was concluded that a single pass with the
22G Acquire needle provided more tissue for histologic evaluation and a better diagnostic
accuracy than a single pass with the 20G Procore needle.
