I have to second what Robin said. The RIGHT surgery for YOU is whatever will best address YOUR eating issues. Do your research and talk to people who have had the various surgeries you are considering. one of the things I liked immediatelky about my surgeon is that, during her info session, they did not push one surgery over others... they gave us a ton of info on lap band, RNY, and DS, and then the nurse and surgeon were there after the session to answer any questions about our individual needs/issues.
I picked RNY for many of the same reasons as Robin. (I *love* ice cream, and I just knew that with lap band I would still eat it... I need the threat of dumping if I have more than just a taste. This was the biggest reason I rejected the lap band for me.) To be honest, one of the things that has surprised me most since my surgery is that I actually CAN be satisfied with just a bite or two of something sweet or high fat... I don't have to have the whole thing.) People who have had the DS will likely respond, though, by saying that with the DS they don't have to worry about dumping and can have more than just a bite or two.
I also did not like the idea of the port, the band slipping, or of having to go through the process of the "fills" and getting everything adjusted early on. The second reason I rejected the lap band was that I was also concerned about the slower rate of weight loss with the band. With so much weight to lose, I was afraid that I would get frustrated and return to eating the things that made me fat in the first place. With the RNY the weight comes of a bit faster, and there are consequences (dumping or diarrhea) if you eat too much sugar or fat. I knew I needed that extra "boost" to my willpower.
I rejected the DS (the other primary "bypass" operation) primarily because of the problems that some people have with gas and diarrhea, because of the increased nutritional deficiencies associated with the greater malapsorption of the DS, and because I thought the small pouch of the RNY would help me better control my portions. I have a friend who is thrilled with her DS, though, and she likes that she can eat larger meals (and, for her, that is worth having to take the extra vitamins and the medication she takes to control the gas).
I was hesitant to alter my digestive system permanently, but the RNY seemed to best address my areas of weakness with side-effects that I could live with (and therefore seemed to offer me the best chance of long-term success).
Good luck with your decision!
