So Bev, will your mother then have an ostomy? No colon left at all? My hubby had about 1/3 of his colon removed because it had gangrene (!!!) and he had an ostomy for several months while the rest of his colon healed. Then they put him back together and now he has no more ostomy... all closed back up.
The ostomy takes a little getting used to but at least it gives you a way to live. Hope your mom recovers well.
