Natural History of the Remnant Pancreatic Duct after Pancreatoduodenectomy for Non-Invasive Intraductal Papillary Mucinous Neoplasm: Results from an International Consortium

CONCLUSIONS: New main duct dilation in the pancreatic remnant after pancreatoduodenectomy for IPMN is common, occurring in 27% of the patients. The duration of surveillance is the main factor associated with remnant PD dilation, suggesting that this is likely a physiologic phenomenon. Although recurrence of IPMN in the remnant is often suspected, only 0.8% of patients develop an invasive carcinoma in the pancreatic remnant requiring completion …
