Fecal Microbiota Transplantation for Radiation-Induced Proctopathy

NCT06776029

The goal of this single-arm trial is to learn if Fecal Microbiota Transplantation (FMT) works to treat hemorrhagic radiation-induced proctopathy. The main questions it aims to answer are: * Dose FMT alleviate the symptom of severe rectal bleeding? * Dose FMT improve the endoscopic findings of proctopathy? Participants will: * Take fecal microbiota capsules by 8 sessions over a 12-week period. * Visit the clinic once every 4 weeks for checkups and tests. * Keep a diary of their symptoms and the number of times they use other supportive care.
