Sure, a VBG is an old procedure called Vertical Banded Gastroplasty. They no longer perform this type of surgery due to too many long term complications. It is basically a stomach stapling combined with a salastic ring stutured into the opening creating a funnel effect. Over time scar tissue has clogged the opening causing severe restrictions. I can't eat anything without pain and vomiting. They couldn't even fit a pediatric endoscope camera through it.
The other was supposed to say RNY bypass.
