Dr Varnell who you said was your surgeon does not list the DS on his website. Be very careful because you don't want somebody doing this procedure who isn't properly trained, and you don't want to get a procedure that you didn't think you were signing up to get. There are many surgeons now selling a procedure call the SADI (single anastamosis) and is not a DS that by definition has two anastamosis.
There are red flags here so please don't just believe what his office is telling you. Thr people on this s site know about just every ds surgeon in North America and some overseas as well. If somebody like
@Larra hasn't heard of this guy as a DS surgeon then chances are very good that he isn't trained on that procedure. That coupled with no DS mention on his website should be a warning sign to do much more in depth homework on this guy.
