Safety and effectiveness for endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) of pancreatic solid and/or cystic lesions

Background: The pathological diagnosis of pancreatic tumors is important to ensure that proper treatment is given and the optimum prognosis is achieved. EUS-FNA is currently the standard method for tissue acquisition and pathological diagnosis of pancreatic mass lesions. The diagnostic yield of pancreatic EUS-FNA has been reported to exhibit a sensitivity of 54%-96% with high specificity and diagnostic accuracy of 83%-95%. However, it occasionally causes serious complications, and factors that increase the susceptibility to such adverse events remain unknown. Method: This single-center retrospective study includ…
