Approaches for the management of intraductal papillary mucinous neoplasms (IPMNs) of the pancreas have been evolving rather rapidly in recent years, owing to the increasing understanding of the natural history of those neoplasms based on observation and accumulation of histological data of surgically resected IPMNs. The strategy to manage main duct (MD)-IPMNs has not been greatly changed in terms of the indications for resection. However, we are taking a much more conservative approach nowadays to branch duct (BD) IPMNs without high-risk stigmata of malignancy.
