Surgeon lists on this website are NOT accurate! You were lucky, at least they were honest with you over the phone. We've seen plenty of other people being told something along the lines of "the doctor does all the wls procedures", they make an appointment, and when they get there, it turns out that the doctor does NOT do all the procedures and will try to talk the patient into whatever he really does do.
Check the list at dsfacts.com. No one listed there does not really do the DS. Whether you will have additional problems as a revision patient, I think that will depend on the individiual surgeon.
