My APR surgery was a result of rectal cancer. Permanent colostomy for 6 months now. It is possible, with a colostomy, to irrigate and to wear only a small stoma cover most of the time.
Please do locate a qualified colo-rectal surgeon and get his/her opinion of your history and current situation. The not-knowing is what is so difficult for all of us! Go to the source for a better appraisal and recommendation. Life doesn't have to be so hard.
