SIZE OF YOUR STOMACH?

IS IT THE DISCRETION OF THE DR OF HOW MUCH OF THE STOMACH HE REMOVES? DOES IT DEPEND ON YOUR STARTING WEIGHT, AGE, ECT ECT. I KNOW MOST DR'S USE A 32 F BOUGIE BUT I HAVE ALSO HEARD THAT SOME DR'S DON'T FOLLOW IT AND SOMETIMES INSTEAD OF REMOVING 80% OF THE STOMACH ONLY 60% IS REMOVED. HAS ANYONE HEARD OF THIS?

As far as I can detect from my own research the size of the stomach left has been reduced over time so doctors may have left more of the stomach say  5 years ago they would not today. I haven't heard of doctors just not following the Bougie but I suppose anything is possible I would think they would try to make the surgery as routine as possible for better success rates.
