My primary doctor happened to be a GI guy, I had to do a *major* presentation to him on all my research, surgeon, and all the pre-surgery testing and counseling, in effect I had to "sell" my surgery to my primary doc to get his ok. It was one of the longest office visits with him ever, and he ultimately approved the surgery.
Thanks for acknowledging the surgery is not a magic bullet, it was not a simple decision for me. Lots of pre/post dedication
