I think I understand the revision a little better
I watched a YT video and it explained the difference in the newer DS and the one I had. It showed how my older one the digestive enzymes enter the intestine at 75cm the new one they enter at approx 3M right next to where I used to have a stomach that has been turned into a tube or thats how the doc that did my endoscopy put it. I don't know when they started introducing the enzymes that far up but I can see how it would make a diff in absorption and digestion. I also see how this would be a fairly easy surgery like he said by disconnecting the tube that carries the enzymes from where it is and seal that up and reconnecting it near the tube like stomach. I am hoping Dr. Heap left everything in there so it's possible.
