Efficacy and Safety of FMT for the Decolonization of MDROs in the Intestinal Tract

The goal of this unblinded randomized controlled trial is to evaluate the efficacy and safety of fecal microbiota transplantation for the decolonization of carbapenemase-producing carbapenem-resistant Enterobacteriaceae (CP-CRE) or vancomycin-resistant Enterococci (VRE) in the intestinal tract. The study is planned to be conducted to test the superiority hypothesis that the decolonization success rate in the FMT group is higher compared to the non-FMT group. Outcome analysis will be conducted through intention-to-treat analysis, modified intention-to-treat analysis, and per-protocol analysis. The main questions it aims to answer are: * primary endpoint: Rate of Decolonization of Multidrug-Resistant Organisms (CP-CRE or VRE) at 1 Month After Fecal Microbiota Transplantation (FMT). * secondary endpoint: Rates of Multidrug-Resistant Organism decolonization at 3 months, 6 months, and 1 year after FMT / Post-FMT Multidrug-Resistant Organism Recolonization Rate and Infection Rate. Patients colonized with multidrug-resistant organisms in the gastrointestinal tract are divided into two groups through obtaining written consent from the patients and random allocation: the Fecal Microbiota Transplantation group (FMT group), which receives FMT, and the control group (non-FMT group), which is observed without FMT. The decolonization status of multidrug-resistant organisms will be monitored every 3-7 days after FMT until three consecutive negative results.
