Classification of intestinal polyps are inflammatory polyps, hyperplastic polyps, tumor polyps, intestinal polyposis, etc. It is necessary to analyze whether surgical treatment is needed according to the etiology of the disease, for example, intestinal polyposis has a high rate of cancerous changes, which can be endoscopically surgical resection. 1. Inflammatory polyps: due to repeated stimulation of the intestinal epithelium by inflammation, which can be secondary to any kind of inflammatory reaction, such as amebic colitis, chronic schistosomiasis, bacillary dysentery and so on. Generally there is no tendency for malignant changes, and the treatment of primary intestinal diseases is the main focus. 2. Hyperplastic polyp: it is the most common non-neoplastic polyp, often multiple, less than 5mm, generally do not need special treatment. But from the appearance can not be identified with tumor polyps, often colonoscopy biopsy resection. 3. Tumor polyps: common tubular adenomatous polyps, chorioadenomas, etc., with the possibility of malignant transformation, it is generally recommended to timely endoscopic resection. 3. Intestinal polyposis: there are more than 100 intestinal polyps with special clinical manifestations. Including pigmented polyp syndrome, familial intestinal polyposis, intestinal polyposis combined with multiple osteoma and multiple soft tissue tumors. The propensity for cancer is obvious and surgery is required. Intestinal polyps require medical treatment as soon as possible to avoid further aggravation.
