• Inflammatory and ulcerative colonic lesions were detected in (35%) near the ratio of colorectal polyps (33.5%) in our study.
• Colonoscopy is not sensitive test in detection of Inflammatory and ulcerative colonic lesions while it’s highly sensitive in detection of benign polyps.
• Inflammatory polyps are the commonest colorectal polyps as they were detected in (35.3%) of all cases with polyps.
• Schistosomal colonic polyposis were not the commonest colorectal polyps as they were detected in (25.4%) of all cases with polyps.
