Endoscopic ultrasound-guided fine-needle aspiration needles: which one and in what situation?
Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is increasingly used as a diagnostic and therapeutic tool for pancreatic and other gastrointestinal disorders. Several factors affect the outcome of EUS-FNA, one of which is needle size. The decision to use a specific needle depends on factors including location, consistency, and type of the lesion; presence of onsite cytopathologist; and need for additional tissue procurement for histology. This review provides a balanced perspective on the use of different needle sizes available, highlighting the differences among them and potential niche applications of each to maximize diagnostic yield of EUS-FNA.
