Colon polyps refer to bulky organisms that are elevated on the epidermis of the colonic mucosa and protrude into the lumen. According to the pathology, they can be divided into: adenomatous polyps (including papillary adenomas), which are the most common; inflammatory polyps, which are the result of proliferation of intestinal mucosa stimulated by long-term inflammation; misshapen polyps; and others: such as mucosal hypertrophy and hyperplasia to form hyperplastic polyps, lymphoid hyperplasia, and carcinoid tumors. Most patients with colon polyps have mild or no clinical symptoms in the early stage, and are often found incidentally during routine colonoscopy or barium enema examination. Since there are no obvious signs of colon polyps, endoscopy is the best way to diagnose colon polyps. Patients should seek prompt medical attention if they have any of the following three symptoms: First, blood in the stool. Patients with colon polyps are most likely to have blood in the stool, but many people will mistake bleeding stools for hemorrhoids, resulting in a delay in the best treatment. Hemorrhoid bleeding is often a bright red drip of blood after a bowel movement. However, bleeding caused by colon polyps is often mixed in the middle of the stool. The second is a change in stool habits. This includes changes in the timing and frequency of stools, as well as constipation or unexplained diarrhea. Especially when constipation and diarrhea alternate repeatedly or cause abdominal pain, it is more alarming. Third, the shape of the stool is abnormal. Normal stool should be cylindrical, but if the polyp is in the lumen of the colon and presses on the stool, it tends to be thinner or flattened when expelled, sometimes with blood traces attached. Colon polyp itself is not scary, but it is the possibility of cancer. The cancer rate of colon polyps is related to the type and size of the polyps. Generally speaking, the cancer rate of adenomatous polyps is higher, and the cancer rate of adenomas larger than 2cm is greater than 50%. However, regardless of the type of colon polyps, they should be removed endoscopically and sent for pathological examination. If endoscopic treatment is difficult, surgical treatment can also be done. After endoscopic treatment of adenomatous polyps, regular follow-up and endoscopic review are needed. Familial adenomatous polyps have a high rate of malignancy, and patients can have a total colectomy as soon as possible. Doctors can take batch microscopic resection according to the size, number and shape of polyps, regular follow-up and review of colonoscopy, which can achieve good results. Colon polyps and colorectal cancer is a disease with family susceptibility and obvious genetic tendency, so it is especially important to be alert. Therefore, once this disease is diagnosed, the patient’s immediate family members need long-term follow-up and timely necessary examinations to achieve early detection, early diagnosis and early treatment.
