If polyps are found in the intestine, 1 cm in size is not serious, they can be removed under colonoscopy. Postoperative pathological histological examination is also required. There are many reasons for the occurrence of intestinal polyps, and if there is a history of recurrent ulcerative colitis, inflammatory irritation can lead to the development of polyps. In addition, there are multiple polyps, which have a certain family genetic tendency, and patients with intestinal polyps will also have abdominal pain, abdominal distension, and even diarrhea or blood in the bowel movements in general. Regular colonoscopy is needed, and lesions smaller than 2 cm can be removed under colonoscopy. If the polyps gradually increase in size or the patient has obvious loss of appetite and weight loss, the possibility of malignant transformation is not excluded, which is relatively serious, and further partial resection of the intestinal canal or lymph node dissection of the abdominal cavity is required if necessary.
