Go to your regular doctor and get a referral to a colo-rectal surgeon. Your regular physican should be able to do this based on the results of your report.
I had APR surgery in February and now have a permanent colostomy. My cancer was on the anal verge, so the surgeon removed the perfectly good anus as well as my rectum. There would not have been enough tissue near the anus for a reconnect. At least you have the option. And ... you have time to research and decide.
I'm not familiar with your disease. Regardless, I'd suggest you not only check out all the ostomy boards online, but that you visit as many professionals as possible and get their opinions. I am satisfied that my general surgeon did a great job, but I didn't have a colorectal specialist available. My oncologist from M.D.Anderson was the deciding factor for me. An ostomy isn't the end of the world, not even the end of life as we've known it.
Good Luck Martha
