There are no surgeons in Dutchess that peform the Duodenal Siwtch. The closest surgeons that do are in NYC. I'd highly recommend figuring out which surgery you want and then pick the best surgeon at that surgery. If you go to a Ford dealer, they normally don't try to push a brand new Chevy on you, well it's the same in the WLS world. RNY surgeons don't normally promote the lap band or the DS.
Dr. Mitchel Roslin in NYC peforms the Lap band, RNY, DS and the VSG. I went to him because he has a reputation of fixing other surgeon's mistakes. I figured if he could fix another surgeons mess, he could do a good 1st surgey on me. He did!!!
I had the DS with him in Feb 2006, I was almost 500 lbs, I lost to goal weight in 18 months and I've been at my goal weight now for over a year. I currently weigh 193 give or take a lb.
