Comparison between Two Types of 22-Gauge Fine-Needle Biopsy for Solid Pancreatic Tumors.

Background: Tissue sampling using endoscopic ultrasound-guided fine-needle aspiration is the gold standard for diagnosing malignant pancreatic tumors; however, its sensitivity and specificity are highly variable. Thus, fine-needle biopsy using cutting needles has been developed to overcome current limitations and improve diagnostic yield. Our study compared two fine-needle biopsy needles for tissue sampling for pancreatic solid lesions.
