That would be determined how much damaged the band does. You can take down a RNY and than do a sleeve. I have seen a couple post RNY to sleeve. I haven't seen a RNY to BOB to sleeve yet here. I could have missed it.
BAND REMOVED 9-4-12-fought insurance to get sleeve and won! Sleeved 1/22/13! Five years out and trying to get that last 15 pounds back off.
