I think when I saw the surgeon before the op he did say that he was going for the bypass but if the bowel wouldnt stretch up enough to reach the pouch then it would have to be the sleeve, band was never mentioned. But it was asuccessful bypass, and key hole, my liver had shrunk quite nicely. Good luck with what ever you decide along with your surgeon, he did say to me at 1 app, i took my hubby along he had reservations, but surgeon looked at me and said if he thought I had any reservations he wouldnt be putting me forward for the surgery, because it is for life. x Good luck with everything. x
