Welcome to the club that nobody wants to be a part of.
I consider it my own version of "Hotel California". I can check out any time I want, but I'll never get to leave.
I have no experience with Pappas, so can't help much there. What I can say is that Atlanta isn't that far from Birmingham, and the Dr's. I have been working with the past few months have been great. Dr. Jeffery Olson and Dr. Doug Mattox at Emory University Hospital are both very well known in the AN circles. Not sure of your situation, but it could be worth a drive over for a 2nd opinion or a 2nd option. My first visit there was with Dr. Mattox. He spent a great deal of time with us (wife and I) explaining what it is I had in my head. He explained the various options available, giving a great deal of info as to the pros and cons of each option. He never once tried to sway my decision one way or the other. There was nothing I asked that he didn't have an answer for. As soon as I decided on the surgery option he set me up with an appointment with Dr. Olson. Again, Dr. Olson went into great detail as to what would be involved, what to expect, what not to expect, and what could or could not happen. My surgery is set up for next Monday morning (the 29th of Jan) so I can't say yet if everything worked out the way I pictured it in my mind, but I do feel at ease with my decision. Hopefully I will be able to post a follow-up towards the end of next week.
Good Luck. I know I have obtained a treasure chest of knowledge from the other posters on this board, and they are always willing to offer up their info on their experiences. Any questions you have, just ask, someone has more than likely been there, done that and already wore out their souvenir tee-shirt.
