Intestinal polyps that are 0.5 to 2 centimeters in length are considered large polyps, and colonoscopic polypectomy is usually recommended. The need for removal of intestinal polyps often takes into account whether they are multiple and whether they are accompanied by other symptoms. Bowel polyps can be categorized into adenomatous polyps and non-adenomatous polyps. Adenomatous polyps need to be removed, while non-adenomatous polyps are recommended for temporary observation. According to the length of polyps, they can be categorized into large, medium and small polyps, with lengths ranging from >2 cm, 1~2 cm and 0.5~1 cm respectively. The symptoms of intestinal polyps are not obvious when they are small, but when they gradually develop and increase in size, they can cause abdominal pain, intestinal bleeding, cancerous changes, and even cause more serious symptoms, such as diarrhea, intestinal obstruction, intussusception, and so on. 1. Non-adenomatous polyps: the chance of malignancy is small, and whether its form is safe can be determined by colonoscopy. When non-adenomatous polyp <0.5cm, it can be observed temporarily without any special treatment, and regular colonoscopy can be done. 2. Adenomatous polyps: the possibility of malignancy is high, regardless of the size, the sooner the polypectomy is done under enteroscopy, the better the prognosis is, and the enteroscopy should be repeated after six months to determine whether there is any recurrence or malignancy. Polyps of different sizes are operated in different ways, and the specialist should decide on the specific surgical method. If intestinal polyps appear in the examination, it is recommended to consult the doctor in time, under the guidance of the doctor to clarify the cause of the disease, to determine whether the need for surgical resection, so as to avoid delaying the condition.
