Hi again,
I haven't tried this because I'm concerned about
abscessing. I've had my fill of those, thank you very much. My colo-rectal surgeon said the plug works better in non-crohns, and only has a 50-60% success rate in crohn's. It is non-invasive and if it doesn't work, it just pops out and you can try again. But there is a risk of abscesses. Stuff could get trapped in the fistual tube as your body works to accept the plug.
I suggest you search for previous posts. I remember that a number of people tried the plug with mixed success. How high is your fistula in the rectum? If it is low (not above the sphincter muscle), then a fistulectomy might be an option. The whole fistula track is cut
open and heals. It has good success. Not for me because the fistula is too high, and cutting that much sphincter would leave me incontinent.
The other option my surgeon told me about is the advancement flap procedure, where a flap of tissue is folded over the fistula hole to seal it. Again, it is more successful in non-crohn's and only 60-70% in crohn's. A high chance of abscess if it fails. My doctor said he wouldn't do anything until the whole area is calm. He said the setons keep it open and draining (so the abscess area attached to the fistula can heal), and to focus on getting the fistula to shrink. Drugs like remicade and humira help here, if I weren't allergic to them. Other drugs are in the pipeline too. So now I am happy with the setons, and am just waiting to see if the fistulas will shrink. Maybe later I will be in a gambling mood to try the advancement flap procedure. For now, I am very happy to not have abscesses!
I'm hoping you have a colo-rectal surgeon who is very experienced with crohn's. Very, very important because we don't heal or react the way normal people do. These are hard decisions and you need the most experienced advice that you can get!
Take care.
