After my colectomy/ileostomy was healed and stitches gone my stoma was out about 1 1/2 to 2 inches and hung down. It was impossible to put a wafer on correctly. I always had leaks and horrible ulcers. My stoma hurt just climbing stairs. My stoma was healthy, just out too much. Surgeon said "I can fix it". So he did and my stoma was then retracted. Hard to get a good wafer seal. Leaks and ulcers. Surgeon said "I can fix it". So he did. Did not work. Still retracted. Constant leaks and blowouts. To this day sometimes out , sometimes retracted. However, with a convatec convex wafer and good ol' Friars Balsam Compound I have no leaks or blowouts.
I don't think I ever lost blood supply to my stoma. It was not black. I think the issue with a prolapse is that it is hard to get the wafer on close enough to the stoma to get a good seal.
Do you have ulcers around your stoma? Do you have trouble getting a good seal?
