Radiation enteritis can be improved by medication, endoscopic treatment, hyperbaric oxygen chamber treatment, etc. If bleeding manifests in radiation enteritis, it is recommended that the relevant people should consult the doctor in time and have early treatment. 1. Drug therapy: all drugs need to be used under the guidance of doctors. (1) Intestinal mucosal protectant: such as aluminum thioglycollate and other drugs, which can play a role in reducing intestinal bleeding, improving stool properties, and improving diarrhea performance by protecting the intestinal mucosa. (2) Hemostatic drugs: mainly for people with more serious intestinal bleeding manifestations, growth inhibitors and other drugs can be used to stop bleeding. (3) Intestinal probiotics: such as Bifidobacterium, Lactobacillus, Enterococcus, etc., which can maintain the balance of intestinal flora, thus alleviating the symptoms of blood in stool and diarrhea. (4) Drugs to promote compensatory proliferation of gastrointestinal mucosa: such as glutamine, etc. By stimulating the growth and proliferation of intestinal mucosal epithelium, it can repair the damage and improve the symptoms such as bleeding. (5) Antioxidants: such as vitamin C, E, etc., can reduce oxidative stress damage, thus protecting the intestinal mucosa. 2. Endoscopic treatment: including laser treatment, formaldehyde coagulation treatment, argon ion coagulation treatment, etc. After finding the intestinal bleeding point under endoscopy, the bleeding point can be coagulated so as to treat the bleeding. 3. Hyperbaric oxygen chamber treatment: regular hyperbaric oxygen treatment can improve the clinical symptoms due to intestinal vascular endothelial damage, and promote tissue repair, accelerate ulcer healing. Radiation enteritis if bleeding manifestation, should actively consult the doctor, follow the doctor’s instructions standardized treatment.
