IPMNs . In the American College of Surgeons Naꢀonal
Surgical Quality Improvement Program, of 478 paꢀents
who underwent pancreaꢀc resecꢀons, 10% were due
to IPMNs, and 23% of these cases showed evidence of
reoperaꢀon . There have not been any recurrences
aꢄer surgical resecꢀon in this cohort.
In conclusion, the diagnosis and management
of this type of lesions is currently standardized with
guidelines that are updated along with advances in
imaging tests and treatment opꢀons. The natural
history of the disease and the events leading to
progression to adenocarcinoma are beꢃer understood
and can be suspected with the results of the imaging
tests. When surgery is indicated, long-term survival
should be similar to that of the surveillance group.
