This article, published in the journal Endoscopy, examines the factors that affect the diagnostic accuracy of endoscopic-ultrasound fine-needle-aspiration (EUS-FNA) for pancreatic and peripancreatic lesions. The study collected data from 219 patients who underwent 221 EUS-FNA procedures and found that mass location on the head of the pancreas and performing two or more needle passes were associated with higher diagnostic accuracy. However, factors such as mass size, needle type, and the presence of a biliary stent did not significantly impact the diagnostic yield. The study suggests that these findings can help improve the diagnostic accuracy of EUS-FNA in their center. [Extracted from the article]
