Is intraductal papillary mucinous neoplasm really a risk factor of post-endoscopic retrograde cholangiopancreatography pancreatitis after pancreatic stenting?

摘要

We read with great interest the article byIto et al. (1). It is extremely impressive and it is importantto know that a risk factor of post-endoscopic retrograde cholangiopancreatographypancreatitis (PEP) after intubationwith a pancreatic stent in high-risk patients is an intraductalpapillary mucinous neoplasm (IPMN). Although there aresome previous reports on the prevention of PEP by a pancreaticstent (2, 3), the report by Ito et al. is of high valueas it is the first report that clarified a risk factor of PEP afterpancreatic duct stenting in patients at high risk in a multicentersetting.
