Comparison of diagnostic accuracy of endoscopic ultrasound-guided fine-needle aspiration with 22- and 25-gauge needles in the same patients

摘要

BackgroundVarious factors, such as the optimal number of passes, aspiration pressure, and the use of 19-gauge and Trucut biopsy needles, have been studied to improve the diagnostic accuracy of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). We retrospectively compared the diagnostic accuracy of EUS-FNA between 25- and 22-gauge needles, which have been widely used recently.
