[Nutrition support trerapy in chronic intestinal radiation damage].

Chronic radiation enteritis(CRE) is a common complication after pelvic radiotherapy, which severely affects patients' quality of life. Surgical treatment of CRE is challenging both for surgical skills and perioperative treatment strategy. Proper preoperative nutrition support therapy can reduce the morbidity of postoperative complication and the use of stoma, while postoperative nutrition support therapy can avoid the intestinal failure. Enteral nutrition should be the primary route of perioperative nutrition support therapy in CRE as possible. Pharmaconutrients aiming at intestinal commensal microbiota and its metabolites may play a role in the management of radiation enteritis.
