You do not have an "army bypass". There is no such thing. You had gastric bypass, commonly shortened to RNY, which stands for Roux-n-Y and describes the intestinal configuration.
It's clear at this point that you don't understand what you have now and why the revision planned by your surgeon is 1) not remotely like the DS, and 2) unlikely to be of much benefit, and 3) will leave you stuck with all the problems you have now from your gastric bypass and potentially add some new GI problems to the mix.
You need to take a step, a giant step back, recognize that the people here, who have nothing to gain from spending their time trying to help you, really are trying to help you to see that you are being offered only what your surgeon knows how to do and NOT what will be an effective revision. You have absolutely nothing to lose by having a consult with a DS surgeon - a real DS surgeon, not someone who tells you - incorrectly - that you will still have your pouch and stoma and that somehow that will be "like a DS" when it won't. Get a second opinion with a real DS surgeon who does RNY to DS revisions. If you then decide that you want go with your local surgeon because that's the path of least resistance, that's your choice. But you should at least know what a DS really is and why what you are getting isn't a DS.
