Don't know if I am spelling this correctly but I wanted to find out if anyone has had these on their colonoscopies. My crohns was in the terminal ileum and it was quite evident when he went in there. I was sort of awake and saw all the raw, red tissue and sores. Throughout my colon were what he told me was apthasous ulcers. They didn't write it on the report though but I have photos of them from the procedure. Did anyone else have them and if so is that very bad or mild in the rest of the colon...at the time of the colonscopy I had been treated for a year for what they thought was c.difficile but as it turns out was crohns. My only treatment for a year was vancomycin.
