Hi! Glad you made it here. Any surgeon who does the DS would do a revision from VSG to DS. The problem isn't with doing a revision on someone who had prior surgery with someone else, it's getting to a DS surgeon. Almost everyone does VSG these days, there are much fewer who do the DS. In your neck of the woods I would recommend Dr. Kemmeter (I have probably spelled his name wrong, hopefully someone else can help), who is a very well regarded DS surgeon in Michigan.
Good think you didn't have gastric bypass - MUCH harder to revise from that to DS and very few surgeons do it.
