Increasing Number of Passes Beyond 4 Does Not Increase Sensitivity of Detection of Pancreatic Malignancy by Endoscopic Ultrasound–Guided Fine-Needle Aspiration

Background & AimsIt is not clear exactly how many passes are required to determine whether pancreatic masses are malignant using endoscopic ultrasound–guided fine-needle aspiration (EUS-FNA). We aimed to define the per-pass diagnostic yield of EUS-FNA for establishing the malignancy of a pancreatic mass, and identify factors associated with detection of malignancies.MethodsIn a prospective study, 239 patients with solid pancreatic masses were...
