I know you asked about US surgeons, but since a bunch of people have said that and it turned out they also meant Brassard... He has a "preference" for lower BMI, but is willing to be flexible; I was 5'8" and about 210 bs when I had surgery with him, and although they'd said in email that losing a bit of weight from the 230 I was would be better, nobody said a word or even weighed me when I showed up. I even got a letter from my GP saying I was in fantastic health for surgery, which they also didn't look at but gave me some peace of mind.
Honestly, the biggest issue for surgery isn't weight per se, it's fitness; the healthier and fitter you are, the faster you're likely to recover. I bounced back beautifully, and I credit that in part to all the exercising I'd done for months beforehand. In your specific case, you also have extenuating circumstances that might convince some surgeons to make an exception.
Good luck.
