Rectal polyps refer to bulging lesions on the mucosal surface of the rectum that protrude into the intestinal cavity, including adenomas (including villous adenomas), childhood polyps, inflammatory polyps, and polyposis. Rectal polyps, also known as rectal adenomas, can be classified as solitary or multiple. Solitary rectal polyps are mostly seen in children aged 2 to 8 years old, and are rarely malignant; multiple polyps are more likely to occur in young adults, have obvious family heredity, have a wide range of lesions, and are prone to malignancy. The main symptom of this disease is blood on the surface of the stool, the clinical manifestations are as follows: 1, intestinal irritation symptoms: mainly manifested as diarrhea or increased number of bowel movements, secondary infection can appear mucus-purulent blood stool. 2, blood in the stool: fresh blood, covered on the surface of the stool and not mixed with it. The polyps with tips at the lower end of the rectum may come out of the anus during defecation. 3.Proctoscopic examination: adenomatous polyps are round with light red and shiny surface mucosa. Villi papillary adenoma is lobulated, cauliflower-like, soft as a large sponge polyp. Inflammatory polyps have long red tips. Proliferative polyps are mostly mound-like elevated nodules. 4, rectal finger examination: polyps in the middle and lower rectum, finger examination can be palpated soft, smooth, active nodules. 5.If multiple polyps are found, sigmoidoscopy or fiberscopy will be performed to exclude multiple polyps and colonic polyposis. Rectal polyps are often long in the lower back wall of the rectum (about 70%), 90% of the single, most with a tip, the tip length of 2-5cm, etc., can move. Polyps without a tip are about 10% and generally less. The polyps are generally round or ovoid, small like rice, large like walnut or egg, brittle, smooth surface, pink color, due to the long-term friction of the feces more ulceration bleeding. 70% of rectal finger palpation can be soft as bean size round mass, can move, no pressure pain. Polyp with higher or smaller location is not easy to find by rectal examination, so proctoscopy or sigmoidoscopy is needed. Papillary polyps are often solitary, a few are multiple, with a wide base, no tip or short tip, with elongated villous-like protrusions on the surface, and prone to malignant transformation. Any polyps without a tip and with a wide base should be regarded as precancerous lesions and should be examined by pathological section as early as possible.
