Fecal Microbiota Transplantation and Analysis of Fecal Microbiome in IBD Patients

Fecal microbiota transplantation will be performed to the IBD patients, and microbial analysis will be done for donor and recipient feces. Fecal microbiota transplantation will be done twice via colonoscopy, with one month of duration. During the early stage of Fecal microbiota transplantation, recipient feces will be analyzed for the intestinal microbiota frequently. Clinical outcome will be assessed 1month, 2month, 6month, and 1 year after the transplantation. Relevance of intestinal microbial change and clinical outcome after transplantation and factors associated with successful clinical outcome will be investigated.
