There is a surgeon there, I think his last name begins with a "W" and he is supposed to be good. You can also ask this question at www.j-pouch.org
If you have an ileostomy, the surgeon removes your large intestine (colon). If you have a colostomy, the surgeon leaves your large intestine (colon) in.
I'm unsure of why my colectomy quit working. It's not a guarantee, so I'm glad that I had 2 good years. Colonic inertia is a very touchy thing. My small intestine was really inflamed from the original ileostomy surgery that was 2 weeks prior to my emergency surgery.
