Study summary

Radiation enteritis is one of the most feared complications after abdominal or pelvic radiation therapy.The gut microbiota is considered to constitute a "microbial organ" which has pivotal roles in the intestinal diseases and body metabolism. Evidence from animal studies demonstrated the link between intestinal bacteria and radiation enteritis. This clinical trial aims to evaluate the efficacy and safety of fecal microbiota transplantation (FMT) for radiation enteritis.

Read the detailed description

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.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 30, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
