Thanks for all the info : )
My GI doc said there are a small % of patients where there are no leftover tell tale sign the disease was even there when in remission but in the majority it leaves traces of previous damage. Don't get me wrong, I 'm happy that my colon fully returns to normal when in remission...just wish remission would last longer than 2 months : (.

Hey bbc, well you have to understand that a standard biopsy can only determine the presence (or absence) of inflammation, and the kind of microscopic changes that have occured on that small strip of tissue. A GI will usually do a few biopsies when performing a scope, and will usually go for the most inflamed looking areas. The diagnosis is set by the GI, and a biopsy is only used to confirm that the inital diagnosis is correct. Now, you would think that it would be able to determine for example if you have Crohn's or UC, but it can't. It can, however, determine if the inflammation is infectious in nature, if there is evidence of dysplasia or hyperplasia (which can lead to cancer), if the inflammation is chronic or acute, etc.
What I'm saying is that visual inspection by a GI is more important when determining the severity of the disease, because he can see how much inflammation there is, he can see if there is some stricture formation, colonic friability (normal mucosa doesn't bleed when rubbed gently, inflamed mucosa does), and more. So if he says it's mild, he probably means that, while there is extensive involvement, the degree of inflammation isn't as bad as it could be.
