happygirl, it's unlikely that the pouch itself is stretched - it's more likely that the stoma, the connection between your pouch and instestines is stretched. So to redo your stoma, they would essentially have to reduce your pouch further (closing off the current stoma) and reduce your intestines further (attaching at a different point), thereby increasing your chances of malnutrition.
My surgeons will do the rose/stomaphyx, but admit that it generally doesn't solve much (not sure why they do it then... I hope they're getting away from it!).
Are you sure that just going back to basics, protein-forward eating plan, getting in 80-100 grams per day, complex carbs, minimal to no refined carbs won't make a difference for you? Particularly if you add in movement/exercise?
