EVERYTHING REGARDING REVISION FROM BAND TO SLEEVE

I never had a band and can not speak to any statistics related to that revision.

I believe you mentioned you are going in for an endoscopy. That is a really important procedure to have prior to deciding on the VSG. If it is determined you have a damaged esophagus from GERD, then you should really consider an RNY. The RNY often cures GERD, while the VSG often creates it.
