Fecal Microbiota Transplantation for Radiation Enteritis

The present clinical trial aims to re-establish a gut functionality state of intestinal microbiota through fecal microbiota transplantation (FMT) for radiation enteritis (RE). FMT is the whole profile of fecal microbiota transplantation. At enrollment, "Shared Decision Making" intervention was applied to support patient involvement in making health decisions. Patients have opportunity to choose fecal microbiota transplantation (FMT). Patients will receive follow-up for at least 12 weeks. Blood test, endoscopy and questionnaire will be used to access participants at study start and at study completion. Fecal microbiota compositions, blood and urinary metabolic profiles of patients will be analyzed to assess associated microbial changes.
