Reader Comments:
Hopley et al. conducted a well‑designed, single‑center observational study using a large 17‑year real‑world cohort of 1,191 patients with presumed benign branch‑duct intraductal papillary mucinous neoplasms (BD‑IPMNs). The long median follow‑up of 9.74 years and the inclusion of both imaging‑only and imaging‑plus‑EUS groups strengthen the reliability of the findings. A key strength is the identification of a clear “window of opportunity” for surgical intervention within the first two years of surveillance, after which the incremental benefit of continued monitoring declines sharply. The authors also provide compelling data that patient age and comorbidity burden (Charlson comorbidity index) critically affect net benefit, supported by competing risk analyses from independent groups (Crippa et al., Gut 2024). Limitations inherent to the single‑center, retrospective design, such as potential selection bias and lack of external validation, are appropriately acknowledged. The manuscript is written in clear, standard academic English. Abbreviations are defined at first use, tables are properly formatted, and the flow of information is logical. The language is concise, respectful, and meets the journal’s requirements for scientific reporting. Overall, the scientific quality is high, and the presentation is professionally polished.

Reader Comments:
This is a highly practical and timely observational study by Hopley et al. The management of presumed innocent branch duct IPMNs often necessitates an overwhelming volume of serial cross-sectional imaging and EUS procedures, which places a heavy demand on diagnostic resources and creates a prolonged psychological burden for patients. By demonstrating that the diagnostic yield of continued investigations dramatically drops after the first two years, the authors provide a strong, data-driven argument for refining our protocols. Establishing clear, objective thresholds, specifically a maximum cyst size of < 30 mm on imaging and a serum CA 19-9 of < 43 KU/L, offers a reliable baseline for predicting high-grade dysplasia or malignancy. Safely de-escalating follow-up for stable lesions after two years, and potentially discharging patients at the five-year mark, is a necessary evolution in pancreatic surveillance pathways. This approach allows multidisciplinary teams to concentrate advanced imaging and interventional resources during that critical, early front-loaded period where the opportunity to detect and definitively resect PDAC is actually at its highest.

Reader Comments:
This single-centre, observational study offers pragmatic evidence to support de-escalating surveillance in presumed “innocent” BD-IPMN. The front-loaded nature of actionable findings and surgery—88% within two years—along with the predictive thresholds (serum CA19-9 ≥43 KU/L and cyst size ≥30 mm) are clinically useful and align with evolving guideline debates. Importantly, the authors highlight declining operability with time, an underappreciated real-world constraint that strengthens the case for time-bound surveillance and potential discharge at five years when cysts remain <30 mm and CA19-9 <43 KU/L.
Overall, this is a valuable contribution that reframes surveillance intensity around early yield, patient fitness, and simple biomarkers, offering actionable criteria for de-escalation while acknowledging residual PDAC risk.
