My band came out in an emergency situation, I went into surgery thinking that they would just be repositioning my band, but they could not so they took it out. Since I had not had time to research or make a decision on a revision surgery, they just took it out and then we decided to go to a sleeve later. So in my case it was just lack of knowing what was going to happen once they opened me that kept him from doing the 2 in 1.
Oh, and now that I have read up on it, I am glad that I am waiting.
