As Mysticobra suggested, ask the surgeon to make your stoma long so it sticks out, and "hangs" away from your body. I only had a temporary stoma and now have a j pouch, but my surgeon didn't make my stoma long enough, or use a rod to hold it in place temporarily, and it retracted to below skin level. The burn every time it emptied and the leaking was excruciating, and thankfully it was temporary. For your permanent stoma, longer is better. Good luck with your surgery.
