If yes, how was your experience? Please share.
I realize I keep putting the entire question in the subject line, lol. Sorry, figure that speeds up responses. Hit me!
If you're in this locale, it makes the most sense to go to Dr. Greenbaum, unless you want to go cross-country to Dr K, Dr Rabkin, or Dr Ayoola.
I personally opted against Dr Elariny. I was greatly put off by the whole group that I met. I'm sure he's a great surgeon, it just was not the right fit for me. His name does not get mentioned as a revision surgeon, so I'd steer clear for that reason (personally).
I was an Elariny RNY patient in 2006, and I consulted with him for a revision to the DS in 2015/2016. After my consultation, I decided there was no way I'd use him again. I decided to travel all the way from VA to California to be Dr. Keshishian's patient, and my surgery is tomorrow and I couldn't be happier.
Dr. Greenbaum does RNY to DS revisions on a selective basis. You would need to provide him with the operative report from your RNY, which you should have anyway for any potential revision surgeon, so he can determine how it was done and whether or not he'd be willing to do your revision. But he certainly has a good reputation.
