VBG - vertical banded gastroplasty - stomach stapling only
Surgery invented by Dr. Edward Mason when he felt long term vitamin deficiencies from gastric bypass made the procedure not appropriate for most patients.
Although long term patients seem somewhat uncomfortable (and many I've met
have regained most of their weight), normal digestion is retained possibly
making the surgery safer in the long term. Note: this surgery has been widely
replaced by the adjustable lap band.
