Bubba,
My surgeon, Dr Z Cohen, who did and redid and re-redid mine since 1979 says differently. According to him you can redo them as long as you have enough intestine. He also flips them over to create new valves so that he does not need more than 30cms of small bowel to do it...saves a lot of bowel that way. He always told me that I had enough to redo my pouch 3xs if needed.
