MTFs that perform lap band???

Hi All Can anyone give me a list of all the military hospitals that perform lapband. From what I have seen on messageboards Walter Reed, Fort Bliss ( Jan 07), and Wilford Hall at lackland AFB (this one i am uncertain of) are all doing it, or attempting to get a program started. I have been attempting to look this up for months with no definate results other than I have spoken to folks who had it done at Walter Reed. My other question is if it is possible to travel outside your region for the procedure. Thanks for any and all help Cam
