High-frequency electrosurgery is usually required for intestinal polyps over 0.5cm in size or if they are diagnosed as adenomatous and have the potential to become cancerous. High-frequency electrosurgery refers to the use of a small electric knife to remove polyps under the colonoscope. 1. Size more than 0.5cm: when the size of intestinal polyps is more than 0.5cm, it means that the development of intestinal polyps is faster, and if it is not resected in time, it may lead to blood in the stool, abdominal pain, and other symptoms or even further deterioration, so it is recommended to do high-frequency electrosurgery for the size of intestinal polyps that is more than 0.5cm. 2. Adenomatous intestinal polyp: when the intestinal polyp is diagnosed as adenomatous, it means that the intestinal polyp has already developed to a more serious stage. Generally speaking, adenomatous intestinal polyp is one of the causes of colorectal cancer, therefore, in order to prevent colorectal cancer, it is necessary to do high-frequency electrolysis. 3. Possibility of cancer: For intestinal polyps, if the base of the intestinal polyp is wider and the content of villi is high, it signifies that there is a high possibility of cancer, and high-frequency electrosurgery is needed as soon as possible to prevent intestinal polyps from becoming cancerous. For patients with intestinal polyps, they should go to the hospital as soon as possible for examination and resection, and it is not recommended to delay to avoid delaying the condition.
