Mayo was able to confirm diagnosis of insulinoma and find it with endoscopic ultrasound. Everyone was wonderful. Kind, compassionate and knowledgeable. I am scheduled for surgical removal on 11/27. I am confident in the care I will receive. My worries now are centered around insurance coverage. Working with them to try to get the needed documentation. Sounds like they will approve the insulinoma removal at reasonable and customary. I will need to cover costs above this. I was advised to have my gall bladder removed. I may have to do this in a separate surgery at home.
