I will read them again but what I meant was that the older guidelines I thought had said to do nothing about IPMNs if they are less than 3 but the newer 2017 guidelines if I remember correctly are saying that if a person also has dilated ducts and or other concerning symptoms then you do do something regardless of the size of the IPMNs. In some cases that could mean just yearly MRIs to follow and in some cases it might mean surgery.
