That's a shame, but I can't say that I'm surprised. We have yet to learn of a surgeon doing the DS in your state. Many people have to travel to get a DS, and IMHO it's well worth the effort. Traveling for surgery is a one time thing; you live with the results of the surgery, good or bad, forever.
The SADI is not the same as the DS. The long term results are not known. Some surgeons are touting it as less risky than the DS, but in reality, the one less anastomosis is about the easiest and least risky part of the DS, and that's the only thing that is avoided. It is also not a standard of care bariatric operation in the USA. Some surgeons (obviously I'm not saying your potential surgeon is doing this!) get around the lack of an insurance code for this operation by using the DS code, even though the description of this code clearly states that it has 2 anastomoses. At some point the insurance companies are going to catch on.
Of course you should continue reading and learn all you can about this before making your personal decision. There are several really good discussions about this on this forum already, and hopefully someone like
@southernlady will come along and provide links for you.
