Have 1st visit @Mayo Clinic next week due to removal of ALL intestines & rectum w/ileostomy. Faild Revrsl. Stoma has 3 holes instead of 1... Why?

Very complex. The folks at Mayo are literally the world's experts on complex colorectal problems. They will take a complete history and physical examination and may get more tests before making a recommendation. I would listen to whatever they say!
