Yes, I am seeing Dr Ayoola. He is on the list. I am traveling from AZ to TX. I’m just impatiently waiting to to hear back from his office after all the testing he ordered. I figured it couldn’t hurt to ask what others have been through.I am a RNY to DS and had a fistula but that was not known until I was on the operating table. Everything is very individualized -- it will depend on your insurance, type of fistula, surgeon, etc. Be sure to only go to an experienced RNY to DS surgeon as it is a very difficult and specialized surgery. This may mean you have to travel out of state.
