Crohn's Colitis

I have a question regarding Crohn's Disease versus 'Crohn's colitis'. Some
background: I was initially diagnosed with Crohn's Disease in '82 when I
had a resection done (approx 1 foot or so of both small and large and my
appendix removed). Since then, I have not had too much trouble with flares,
except for two mild to sever bleeding episodes, the last about 10 years ago.
A few years ago, I had a kidney stone removed. During tests to discover the
source of the pain, it was found that the site of the resecton had
constricted to around 1/4 inch in diameter due to inflammation and scarring.
They stretched the stricture with a balloon at the end of the
proctoscope(?). It turned out I had a kidney stone (and I am told that my
missing intestinal section makes me more susceptible to forming stones in
the future) and it was removed. I am currently (for the past several
years) on Pentasa (1 gm/day). My doc tried me on Imuran, but I had a bad
serum reaction to it. For the past several years, I also have had the
pleasure of having a perianal fistula. It doesn't really bother me too
much, except that it itches and weeps some pus regularly.

Now to the question: As I understand it, if both the large and small
intestine are involved, it is Crohn's colitis, not CD. So do I have Crohn's
colitis, or 'only' CD?

Response 1:

Actually the term "Crohn's colitis" is more of less a descriptive term
to categorize Crohn's disease that is confined solely to the large
intestine and to differentiate from Ulcerative Colitis(which isn't
always easy). The location breakdown of Crohn's disease is as follows;
35% have only small bowel involvement, 45% have both small bowel and
large bowel(colon) involvement, and about 20% have disease confined to
colon(Crohn's colitis).

Regardless of the location it is still referred to as Crohn's disease,
although descriptive terms (or subtypes) such as Crohn's colitis,
ileitis, ileocolitis, etc. might be used to further describe the disease
by location.

Response 2:

Crohn's Colitis is generally used to described Crohn's Disease of the
large intestine. the colitis part refers to the location of the
disease.
