Looking for information on switch after 13 yrs from By-pass
I can't speak from personal experience with revision, but definitely there are people who have done this and been much more successful with the DS. My concern, though, is that you need a surgeon experienced with this specific type of revision, as it's the most complex and high risk bariatric surgery being done. There are only a handful of surgeons in the USA doing it, and the one you named isn't one of them. In fact, I've never heard of him as a DS surgeon at all, and that's after over 7 years on this forum and other DS forums. So you are going to need to look elsewhere.
the closest to you would probably be Dr. Roslin in NYC. You are going to need to travel, and might as well accept that idea now.
