This is a single-center, real-world observational study combining retrospective and prospective cohorts to systematically evaluate the long-term effectiveness and safety of Fecal Microbiota Transplantation (FMT).
The study plans to enroll approximately 4,000 patients who have undergone FMT for a range of diseases, including recurrent Clostridium difficile infection, inflammatory bowel disease, functional gastrointestinal diseases, and certain extra-intestinal disorders.
The primary objective is to assess the real-world clinical remission rates at 3 months, 1 year, and 5 years post-FMT. Secondary objectives include evaluating long-term safety and adverse events, measuring improvements in quality of life, and exploring factors (such as delivery route, donor selection, and patient characteristics) that predict treatment success. Data will be collected from medical records and through planned follow-up visits. Advanced statistical and machine learning models will be used to analyze the data and build predictive models.
The results of this large-scale study will provide high-quality evidence to support the standardized and precise clinical application of FMT.
