Outcomes
pancreatic malignancies
ADVERSE REACTIONS, SECONDARY, COMPLICATIONS
The primary outcomes of the study were: (1) to compare the diagnostic accuracy, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and area under the receiver operator characteristic curve (AUC) of CH‐EUS MASTER and endoscopists in diagnosing benign and malignant pancreatic masses under CH‐EUS; (2) to compare with the diagnostic accuracy, sensitivity, specificity, PPV, NPV, and AUC of the CH‐EUS MASTER group and control group undergoing EUS‐FNA. The secondary outcomes of the EUS‐FNA procedure included first pass of diagnostic sensitivity for pancreatic malignancies, incidence of adverse reactions and complications.
