High-risk stigmata are retained, with an enhancing mural nodule of 5 mm or more, main duct of 10 mm or more, obstructive jaundice and positive cytology as indications for surgery in fit patients. Worrisome features now include cyst growth of 2.5 mm or more per year, new-onset or worsening diabetes and acute pancreatitis, alongside the earlier criteria.\n\nThe guideline addresses when surveillance can be stopped (after five years of stability in cysts under 2 cm in patients who would not be surgical candidates), the role of cyst fluid molecular analysis, management after resection, and the need for randomised trials of surveillance strategies.","asOf":"2026-09-21","links":[{"label":"Pancreatology 2024","url":"https://doi.org/10.1016/j.pan.2023.12.009"},{"label":"PubMed","url":"https://pubmed.ncbi.nlm.nih.gov/38182527/"}],"tags":[],"related":[],"cancers":["ipmn-cystic-precursors","pancreatic"],"sections":[],"technologies":[],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"journal":"Pancreatology","year":2024,"doi":"10.1016/j.pan.2023.12.009","pmid":"38182527","authors":"Ohtsuka T, Fernandez-Del Castillo C, Furukawa T, et al.","paperType":"guideline","findings":["New worrisome features: cyst growth 2.5 mm or more per year, new-onset or worsening diabetes, acute pancreatitis.","Surveillance may stop after five years of stability in small cysts in patients unfit for surgery.","Recommendations graded by evidence quality for the first time."],"whatItMeans":"The current international standard for deciding which pancreatic cysts to operate on, which to watch and for how long.","caveats":["Most recommendations still rest on low-quality retrospective evidence.","Differences from the European and American guidelines persist, particularly on stopping surveillance."],"changedPractice":true},"route":"/key-papers/paper-kyoto-2024-evidence-based-guidelines-ipmn-pancreatology-2024/","neighbours":{"cancer":[{"id":"ipmn-cystic-precursors","kind":"cancer","name":"Intraductal papillary mucinous neoplasm and other pancreatic cystic precursors","route":"/cancers/ipmn-cystic-precursors/"},{"id":"pancreatic","kind":"cancer","name":"Pancreatic ductal adenocarcinoma","route":"/cancers/pancreatic/"}]}}
