Abstract: Surgical management of chronic radiation enteritis(CRE) had replaced home parenteral nutrition(HPN) as the most a critical component.The era of function preservation surgery,surgical management of CRE has also advanced from mitigating severe complications to preserving intestinal function.Malnutrition had been shown to be a risk factor for poor perioperative outcomes of CRE patients.The prevalence of malnutrition in CRE patients was higher and severer malnutrition was more common.The patients needed more long-term MNT than guidelines recommendations in surgery and the ratio of parenteral nutrition or combination of enteral nutrition was higher.The short bowel syndrome patients underwent extensive intestinal resection should be considered to continue MNT after discharge.Immunonutrition has the effect of suppressing excessive inflammation,however,its effects in improving nutritional status and enhancing postoperative recovery of gastrointestinal motility need to investigate in qualitative research.

Key words: chronic radiation enteritis; function preservation surgery; medical nutrition therapy; malnutrition
