I missed this post before because I probably skipped it because the subject title was so vague. Anyways, the very first thing I would do is find out for certain if you are pregnant or not....
I had a sigmoidoscopy while pregnant with no problem. How have they determined you have a fistula? Do you have stool draining out somewhere or did they do a sigmoidoscopy? I would find some new doctors and make sure you don't have Crohn's. You have 2 symptoms of Crohn's. Remicade is very helpful at closing fistulas but it is not recommended in pregnancy. My GI told me that my 1 inch deep ulcer has not opened into my vagina yet, (he checks it when I have a sigmoidoscopy or colonoscopy) but if it does open, that I need immediate surgery.... Although I have heard of people not getting surgery for their fistulas on the Crohn's board. The Crohn's board can offer you a lot more info on Fistulas than this one since fistulas are not common in UC. Try not to freak out too much. I know how it is to get such shocking sudden news. The next step is either surgery or aggresive meds like Remicade if you do have a fistula, depending on what your GI says. I would make absolutely sure these doctors are right that you have a fistula. Where is the fistula coming from and going to and what tests were done to find it? What surgery would they do? A resection or a repair or what?
