OBJECTIVES:
A large-caliber needle such as a 19-gauge needle may help overcome the limitations of a 22-gauge needle by acquiring a larger amount of tissue sample. However, there has been no well-designed comparative study for endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) with a 19-gauge aspiration needle. We conducted this study to compare the diagnostic accuracy of EUS-FNA using a 19-gauge aspiration needle with that using a 22-gauge aspiration needle in patients with solid pancreatic/peripancreatic mass.
