Abstract
Revised clinical criteria for autoimmune pancreatitis AIP have been proposed by the Research Committee of Intractable Disease of the Pancreas and the Japan Pancreas Society These criteria require distinguishing AIP from neoplastic lesions However this can be difficult and patients often undergo surgery on the basis of suspected pancreatic cancer PCAIP was diagnosed in 25 patients at the Aichi Cancer Center Hospital ACCH according to the revised AIP criteria In each patient endoscopic ultrasonography EUS was used to describe the conventional pancreatic parenchymal and ductal features of chronic pancreatitis Sahai criteria and other abnormal features namely diffuse hypoechoic areas DHAs diffuse enlargement DE focal hypoechoic areas FHAs focal enlargement bile duct wall thickening BWT lymphadenopathy and peripancreatic hypoechoic margins PHMs We compared these features between 25 patients with AIP and 30 patients with pancreatic cancer resected at ACCH
