1/2 and 1/2-anyone had half rny and ds?
Ask him for pictures. This doesn't sound anatomically possible, as the RNY has a pouch with a stoma, but the DS retains the pylorus.
I know a lady who had a VBG and they didn't do anything to her stomach, just did the intestinal arrangement. She's done very well indeed, AND she still has her pylorus.
VBG revisions can be very difficult, esp if mesh was used in the original surgery. Even so, and with the utmost respect for Dr. Anthone, I would suggest you get a second opinion with one of the surgeons who does a lot of revisions to determine whether or not the stomach could be revised to a DS sleeve, and whether or not this would be higher risk than what Dr. Anthone has planned. It would then be up to you to decide how much risk you are willing to take.
You can contact either Dr. Rabkin or Dr. keshishian via email and see what they say. You have nothing to lose by asking.
