I too have Gastrinomas had a perforated esophagus had major surgery to repair it. They discovered it was in the liver. Currently my pancreatic tumor is 4.5 CM I am grade 2 ki-67 is 7% no mention yet of whipple I hope I don’t have to get that done. I had high burden of liver tumors that had to get controlled as my gastrin was 2,000 2 years after SIRT radiation it is down to 200 I now have tumors on the spine still feel pretty good. I am glad you are going to Mayo hopefully you don’t need a whipple good luck and let us know what happens. Please get a second opinion before the whipple we are all different it may be the best option a good team will know that!
