The optimal surveillance interval for branch duct intraductal papillary mucinous neoplasm (IPMN) of the pancreas depends on the size of the cyst and morphologic changes detected during the initial 6-month follow-up. Findings from a large-scale, international cohort study suggest that for patients with cysts smaller than 20 mm and no morphologic changes during a 5-year surveillance period, surveillance may be discontinued if they are unfit for surgery or have a limited life expectancy of 10 years or less.
