Core Tip
Core Tip: The de-escalation criteria proposed by Hopley et al for branch duct intraductal papillary mucinous neoplasm surveillance are clinically pragmatic and broadly supported by the available evidence. However, their radiological methodology requires greater transparency. Inter-observer variability in magnetic resonance imaging cyst size measurement, the absence of standardised imaging protocols, evolving definitions of worrisome and high-risk features, and the lack of a specified post-de-escalation imaging algorithm represent important unresolved issues. A dedicated pancreatic radiologist within the multidisciplinary team and the adoption of structured reporting standards are essential prerequisites for the safe translation of these findings into routine clinical practice. Addressing these points is meant to strengthen, not undermine, the de-escalation strategy proposed by the authors.
