Should I ask for more tests?

Background: I found blood (lots) in my stool when I was pregnant over 2 years ago. After ruling out it being pregnancy related my OB sent me to a gastro who did a small scope in his office. He saw mild inflamation but since I was pregnant he and I agreed to hold off on a colonoscopy until after I had the baby. I didn't have any other symptoms (well I was pregnant so my whole body was out of whack) so my doctor thought it was something mild like ulcerative proctitus and just put me on canasa. The canasa helped my stools become solid again and the blood loss significantly lessened.

After I had my daughter the bleeding stopped as did the loose stools. My doctor and I decided on a flexsigmoidoscopy since I was breastfeeding and didn't want to be put under for a full colonoscopy. This seemed like a good idea for both of us since he thought the only affected area was the bottom of my colon. The results of this scope and the biopsies were inconclusive and there was no inflamation. The doctor said he would keep my original diagnosis (ulcerative proctitus) and that it was probably the canasa that had caused all of the inflamation to disappear so he couldn't see it in the scope.

Now, a year after my first scope and almost two years after I first started showing symptoms, I started bleeding and having loose stools again. This time I had major stomach issues when eating ANYTHING and I was getting to the point where I didn't feel like eating at all. I went for a second opinion and he said my first doctor had done everything right but now I needed to go for a colonoscopy. I went back to my original doctor, whom I like a lot better, and he scheduled the procedure. He also put me on Asacol in addition to refilling the Canasa (which I had taken myself off of after a month of no symptoms).

Results: The colonoscopy showed no inflamation in the bottom of my colon but major inflamation in the upper part of my large intenstine. The biopsy results were inconlusive so with these results it was unclear if it was UC or CD. My doctor gave me the new diagnosis of indeterminite colitis since the area affected is not a normal UC area although it was one continuous area and not spots all over like CD. He said he is 90% sure it is CD as that is what he has seen most cases of indeterminited colitis turn out to be. To treat this he has upped my does of Asacol from 1 pill 3 times a day to two pills 3 times a day and lowered my dose of Canasa from twice a day to once a day (since now he thinks it wasn't really getting to the affected area). My stools are now solid and I haven't had any bleeding for a while (I only bled for a short period of time this time) but there is still a lot of mucus in my stools.

My question is are there other tests my doctor should be doing to determine weather it is CD or something else? What about looking at the small intestine?

I really don't want to have to go to a thrid doctor for all of this because lets face it this is not fun stuff! But, if my doctor isn't doing all he can to diagnoise and treat me then I will do what I have to do for my health.
 
Hi Caradawn, to treat IBD properly you really need an accurate "roadmap" of the disease. In your case you should look into an MR enterography to look into the small bowel - if that shows evidence of IBD then the diagnosis is Crohn's. You can also ask for some simple blood tests to help, in particular ASCA and ANCA (positive ASCA and negative ANCA more likely Crohn's with the reverse more likely UC.

I was wondering if you were on the suppositories just prior to your colonoscopy, if so, the rectal sparing seen at your colonoscopy would be entirely consistent with UC which has had topical (rectal) treatment.

The other option would be to add a thiopurine (Azathioprine or Mercaptopurine) which would treat both UC and Crohns, whereas mesalazine really only targets UC.

Best wishes.
 
Yes I was on Canasa before both scopes (flex and colonoscopy). I did have a blood test taken before I had the colonoscopy and I don't remember the results being any more conclusive than the colonoscopy or biopsied tissue. When I get home I will look at the results (if I have them) and let you know what exactly all the tests said.

Should my doctor be the one telling me I need these tests or is it more normal for the patient to request them?
 
A well informed patient will probably know more than your average doctor about IBD, so it might be worth asking for the tests, unless your doctor is an IBD specialist, then they would order what was necessary.

Unfortunately IBD can be badly mismanaged unless you see someone who deals with it frequently.
