mom4321, if you look on google or yahoo images for "colonoscopy pictures" you should be able to find some pictures of healthy colons. I looked it up after mine too, to see how different my colon looked compared to the healthy ones... I was able to see what they meant by "loss of normal vascular pattern" because the healthy colons looked all veiny and mine is completely smooth, no evidence of veins whatsoever, and just covered with scars on the parts that weren't inflammed, and red splotches all over the inflamed parts.
