Patient: Description of the condition (onset time, main symptoms, hospital visited, etc.): The patient is a male, 49 years old, recently in the Air Force Hangzhou Sanatorium physical examination, electronic video colonoscopy found that about 9 cm from the anus visible about the size of the rice grain bulge, the surface without erosion. He was diagnosed with rectal polyp during physical examination. I have not yet been treated. Please tell me, how to treat it? What should I pay attention to in my daily life? Anal surgery: Colonoscopic excision is sufficient, very traumatic and basically painless. There is no particularly effective method to prevent colorectal polyps Patient: Should they be removed immediately? Patients are afraid of surgery. Will the polyp shrink and recover on its own? During the physical examination, the examiner said to wait for six months and then check again, and if the size of the polyp increases to 3CM, it should be removed. But I am afraid of delaying the disease. Anal Surgery: Generally polyps do not shrink by themselves, unless they are inflammatory polyps. Endoscopic removal is not particularly painful, and is the same as doing a colonoscopy. If the polyp is very small, it can be observed for the time being, but it is easier and less risky to treat when the polyp is small. If the polyp is up to 3 cm, some special techniques are needed to remove the polyp and the risk is greater. In addition, polyps larger than 2cm have a significantly higher chance of becoming cancerous. Patient: Now I understand that the grown polyps cannot disappear and must be cut out. So how do rectal polyps arise? Anal surgery: The pathogenesis of colorectal polyps is not fully understood, and there is no effective what to prevent it. The disease’s very common, only early detection Early treatment, there will be no adverse consequences.
