Role of ERCP in the diagnosis of intraductal papillary mucinous neoplasms.
Mucinous cystic neoplasms of the pancreas may present in a "ductectatic" form, which parallels a distinct clinical presentation. We describe six patients with this entity termed mucinous ductal ectasia, or intraductal papillary mucinous neoplasm. All six patients presented with typical clinical and endoscopic findings and subsequently, almost all were found to have mucinous ductal cystadenocarcinomas. The endoscopic and pancreatographic findings associated with an intraductal papillary mucinous neoplasm are characteristic, unique, and yield a high diagnostic accuracy. It is important to recognize these features of intraductal papillary mucinous neoplasm since the tumor has a lower malignant potential than adenocarcinoma of the pancreas, and surgical resection is curative in many cases.
