Colonoscopic polyp surgery usually requires hospitalization, because colonoscopic polypectomy is currently indicated mainly for apparently benign polyps, or multiple benign polyps, which, after endoscopic removal, are usually confined to the mucosa and submucosa. Due to endoscopic manipulation, it is possible to damage the muscular layer or even the plasma layer. Once the colon is perforated, it is usually necessary to perform a timely caesarean section and fistula, otherwise there is a large amount of stool in the intestinal cavity, containing a large number of bacteria, which can easily cause acute diffuse peritonitis, or even infectious shock, and endanger the life of the patient. Therefore, although enteroscopic polyp removal surgery is relatively small, there is a risk of bleeding and perforation, so hospitalization is currently advocated for 1-2 days of observation, and the patient can be discharged when there is no bleeding or perforation. If bleeding or perforation occurs timely surgical intervention is needed to avoid serious complications that could endanger the patient’s life.
