How often should pancreatic cysts be monitored after surgery?
There is no current consensus on the surveillance of pancreatic cysts following surgery, however in most cases a follow-up MRI scan every 2 years is reasonable. In those with low risk cysts, surveillance is recommended every 5 years, as the risk of malignant transformation is so low (put at 0.24% per year).
What are the symptoms of a pancreatic cyst?
