Rectal polyps are generally classified into several types, including adenomatous polyps, inflammatory polyps and polyposis. Adenomatous polyp (rectal polyp) is a kind of benign tumor of the intestine. At first there is a small protrusion on the mucosa, mostly asymptomatic, and gradually grows like a soybean grain, and then as large as a walnut. It is soft and elastic, bright red and bleeds easily. Those without a tip are called broad-based polyps. Some polyps move down due to intestinal peristalsis and stool pushing, and the intestinal mucosa will be stretched into the tip called polyps with tip. Those with higher position are called high polyps, which are not easily detected. The lower rectal polyp or the longer tip can come out of the anus when defecating, which is called low polyp and easy to find. Generally after the stool can return, if repeatedly prolapse, gradually can not return to the self, need to send back by hand. At this time, there can be discomfort such as poor defecation, falling, and posterior urgency. Polyp is often single, occasionally multiple. Inflammatory polyps, also called pseudopolyps, are inflammation-induced changes, usually caused by inflammation of the intestinal mucosa, ulcers, chronic dysentery, etc. These polyps are generally not cancerous. To distinguish rectal polyps are benign or malignant, there are generally the following indicators: 1, brittle: during the examination, the polyp is touched with an instrument and bleeds very easily is mostly malignant polyps. 2, ulcers: polyps above a sui condition will not grow ulcers, but if malignant changes occur, ulcers can be formed. Especially polyps with tips usually do not cause ulcers, once ulcers occur, it indicates that it has malignant changes. 3.Activity: firm and firm polyps without a tip are prone to malignant changes. 4, shape: lobulated polyps are prone to malignant change, smooth and rounded polyps are less likely to be malignant. 5, base: polyps with large base and small head are very susceptible to malignancy. 6.Type: Those with a tip are mostly tubular adenomas, which have a relatively low cancer rate. 7.Size: polyps with enlarged size or larger polyps are prone to malignant transformation. Generally found polyps should be surgically treated, the specific methods are electrocautery, ligation, surgical excision. Adult rectal polyps pathological types, with a tendency to cancer, so once diagnosed, it is advisable to perform early surgical removal, do not even consider other non-surgical treatment. With the rapid development of modern medicine, factors such as heart disease, hypertension and advanced age are not absolute contraindications to surgery.
