Well, I'm not a surgeon, but from the way I understood it....when you have a temp ileo it usually a loop. So it's like a garden hose, they fold it, stick the fold through you abdominal wall, and make an
opening there. So, most waste goes out the hole. It is not a complete "Seal", a tiny bit of stool will sometimes get through, and you just pass that and mucus like "normal". After the ileosotmy is taken down, you go through your bum like you used too. I am sure that BM stuff is flowing over stitches and such, but it's just the way it's done, I guess. Everything heals up nicley anyway.
I hope that helps a little, I'm certainly not an expert! :) Good luck on your surgeries! I am much happier after mine!
If at first you do not succeed, then skydiving is surely not meant for you.
Jo - UC, total colectomy and ileostomy on August 24, 2007. Step 2 & ileosotmy switched to left side - May 27, 2008, and take down August 8, 2008. LIFE IS GOOD.
