Pancreatic cysts are small sacs of fluid that grow on or inside the pancreas. Most pancreatic cysts are harmless and only need a series of three MRI scans to rule out any risks to your health. Less often, a cyst may require an endoscopic procedure called EUS/FNA to test it for abnormal cells. In a small number of cases, surgery to remove the cyst is recommended. Using the most up-to-date scientific evidence available, the AGA created a guideline that will help you and your doctor determine the best way to treat and monitor your pancreatic cysts.
