Nowadays, more and more people are paying attention and undergoing colonoscopy. A significant number of people find out that they have colorectal polyps after the examination. So what exactly are colorectal polyps? Why do you get colorectal polyps? What can be done to prevent them? What is colorectal polyp Colorectal polyp is a swelling raised on the surface of the colorectum, which can be adenoma or hyperplasia of the intestinal mucosa, collectively called polyps before the nature of the pathology is determined. Polyps can be solitary or multiple, hereditary or non-hereditary, and their incidence ranges from 1.6% to 12.0% of the total population. Causes of colorectal polyps 1, infection Some reports suggest that the occurrence of adenomatous polyps is related to viral infection. 2, age The incidence of colonic polyps increases with age. 3.Embryonic abnormalities Juvenile polyposis is mostly misshapen tumors, which may be related to abnormal embryonic development. Smoking is also closely related to adenomatous polyps, with small adenomas occurring in those who have smoked for less than 20 years, and large adenomas in those who have smoked for more than 20 years. 5.Heredity The occurrence of some multiple polyps is related to heredity. Patients inherit the defective oncogene APC allele from their parents’ germ cells, while the other APC allele in the colonic epithelium is normal at birth, and later when this allele is mutated, adenoma occurs at the mutated site, and this mutation is called somatic cell mutation. Clinical manifestations of colorectal polyps 1. The common clinical manifestation is blood in the stool, mostly bright red or dark red, small amount, intermittent bleeding mainly. Occasionally, there is haemorrhage in the upper gastrointestinal tract, and long-term chronic blood loss may lead to anemia. 2.Fecal changes, including changes in the time and frequency of defecation, as well as changes in the shape of the stool. 3.The polyps may cause abdominal pain, constipation, bloating, diarrhea, etc. when they are large. 4, rectal polyps with long tips can come out of the anus with defecation. Treatment of colorectal polyps 1.Single polyp can be removed and pathological biopsy can be performed at the same time. 2, multiple polyps or polyps with malignant changes, can be pathological biopsy through the anal anoscope, in order to exclude malignant changes. 3.Low or long-tipped prolapsed polyps can be removed by anal speculation, sigmoidoscopy, ligation or direct removal through the anus. 4.Wide based or multiple polyps can be excised through the abdomen, perineum, sacrococcygeal part of the intestinal wall. 5, high polyps can be high-frequency electrodesection by fiber colonoscopy. 6, polyps with cancer should be performed according to the tumor radical resection. Prevention of colorectal polyps 1, for people with a family history of colorectal polyps should have regular physical examinations to detect the disease early and timely treatment. 2.Keep a good diet. Eat more fruits and vegetables, eat more coarse fiber food, and eat less smoked, fried and pickled food. 3, maintain a good lifestyle, and actively engage in physical exercise to improve their immune system.
