Results Large intestine diseases, i.e. colonic polypus, no-specific inflammation of the colon and rectum, carcinoma of colon, and ulcerative colitis, were mainly found in the rectum and sigmoid colon. Conclusion The rectum and the sigmoid colon are the main invasive sites of polypus, inflammation, ulcer and tumors. Colonic adenomatous polyp is one of the high risk factors of colorectal tumors.
