If bowels look good during colonoscopy can biopsies show a different result, such as ibd?

Yes. In children, a normal appearing bowel on colonoscopy is encouraging, however, microscopic inflammation may exist. Make sure to follow up with your physician to review the results of the biopsies if you had symptoms that led to your procedure in the first place. If the procedure was for colon cancer screening, then biopsies are not important if no polyps were seen.
