[Practice and consideration of fecal microbiota transplantation]

As an innovative therapy, FMT has made a breakthrough in the treatment of recurrent Clostridium difficile infection (CDI). With the rapid development of biotechnology, the relationship between intestinal microflora and diseases has been gradually eluciated. Great hope has also been given to FMT in other intestinal and extraintestinal diseases with ineffective traditional treatment. However, as a new therapy method, FMT still has many unknown fields, such as the selection of clinical donors, the preparation of standardized bacterial solution and capsule, the selection of indications, the matching of donor and receptor, and the prevention and treatment of complications. Since 2012, our center has carried out treatment research and practice of FMT, so far with more than 60 000 FMTs for more than 3500 cases. Based on large sample data and experience, this special issue reports and discusses the above topics, and focuses on the establishment and clinical application of standardized methodology of FMT, which will undoubtedly play a positive role in promoting the healthy development of FMT treatment in China.
