Well, I wish I could say everything was great after I was reconnected, but I cannot...at least for me, I chose to go back to my ileostomy and that was more than 7 years ago. Just this year I elected to have a proctocolectomy(removed colon and rectum) with permanent ileo. My crohn's had progressed to those areas and with a cancer threat and fistulas, I had had enough!
As far as having bm's with an ileo, it is possible. With your loop ileo, there is a second hole, that you probably cannot even see, under the one where waste comes out. Some times there is "overflow" that can go down the second hole, which is why you could be having bm's, too. I freaked out the first time it happend to me! You can also pass mucous which is still produced in the colon even when it isn't used.
