VSG TO DS REVISION?

DOES ANYONE HAVE ANY STATS ON THE REVISION RATE FOR VSG TO A DS?

im looking to find out how common it is to have the  sleeve and eventually need the ds later?

I think part of that depends on how heavy someone is. They say that for lighter weights (150 or less to lose), it should be able to get them to a great weight without anything else. Some heavier weights have to have the DS. Basicially if you work the tool and do as your surgeon says, and he gives you a small VSG stomach (the DS stomach is larger because they have mal absorption) then you should be great with just a VSG.
I had the VSG, and I know that's enough for me. I still have to watch myself to make sure I don't miss a meal or I will start losing again.
