Hi Ann, I have had my ileostomy for more than 50 years (for ulcerative colitis). What I didn't know was that there was trouble during surgery, and although they did the ileostomy, they left the diseased colon/rectum in. Thinking that the "diseased colon was out," you can imagine my surprise when both poop and blood started coming out about a month later (I was still in the hospital). 3 months later, I had the diseased colon removed, but the doctors left the rectum, hoping that it would heal. He envisioned a time in the future when they'd be doing reconnections, but when the rectum didn't heal after 4 years (I was 19), I insisted that it be removed. Removal of the rectum can be a radical surgery, sometimes with complications, so if it's not diseased, sometimes the doctors just leave it there. But I can't imagine that "poop" would stay up there for so many years and not cause problems (infection?). If they/you wanted to get cleaned out, they could do a series of "enemas," and if you're truly impacted (with poop), that should show up on an x-ray. Fast forward about 25 years... my mother needed a colostomy due to a recurrence of uterine cancer that had spread to her colon. We all knew she was ultimately dying from the cancer (she didn't know), but we were all surprised when "poop" started to drain from her vagina. The cancer had eaten its way through the colon walls, and there was nothing more to do for her since the "end" was very near. Even though your doctor thinks that the poop is from the isolated colon, I would still get another opinion. I had UC... my husband had Crohn's, and my two sons have inflammatory bowel disease. Medical diagnosis is not always accurate, so if you have concerns, please be your own advocate. I can't tell you how many times I questioned the doctors and insisted on further testing... to make knowledgeable decisions.
I'm not trying to scare you... but wanted to share my 50+ years of experience... As I told one doctor, it's my time, my money, and my child. Do the test again!!! Not everyone liked me... but sometimes, I was intuitively right. Don't let yourself be intimidated. Best of luck. Marsha
