Endoscopic ultrasonography findings of pancreatic parenchyma for predicting subtypes of intraductal papillary mucinous neoplasms

The subtypes of intraductal papillary mucinous neoplasms (IPMNs) are closely associated with the clinicopathological behavior and recurrence after surgical resection. However, there no established non-invasive methods to confirm IPMNs without surgery. aim this study is predict using findings endoscopic ultrasonography (EUS). Sixty-two consecutive patients who underwent EUS before surgery were retrospectively reviewed. following analyzed their relationship was evaluated: diameter main pancreatic duct, cyst size, number cysts, height mural nodule, early chronic pancreatitis (CP) finding, fatty parenchyma atrophic parenchyma. as follows: gastric (G)-type 38 (61%), intestinal (I) -type 14 (23%) pancreatobiliary (PB) 10 (16%). Fatty significantly G-type (P < 0.0001). Early CP ?2 correlated I-type PB-type or degeneration in comparison other Using above characteristic findings, sensitivity, specificity, accuracy 63%, 92% 74%, respectively, G-type, 57%, 96% 87% I-type, 90%, 94% PB-type. evaluation especially focused on parenchyma, has potential IPMN.
