A standardised model for stool banking for faecal microbiota transplantation: a consensus report from a multidisciplinary UEG working group

Background Fecal microbiota transplantation is an emerging therapeutic option, particularly for the treatment of recurrent Clostridioides difficileinfection. Stool banks that organise recruitment and screening of feces donors are being embedded within the regulatory frameworks described in the European Union Tissue and Cells Directive and the technical guide to the quality and safety of tissue and cells for human application, published by the European Council.Objective Several European and international consensus statements concerning fecal microbiota transplantation have been issued. While these documents provide overall guidance, we aim to provide a detailed description of all processes that relate to the collection, handling and clinical application of human donor stool in this document.Methods Collaborative subgroups of experts on stool banking drafted concepts for all domains pertaining to stool banking. During a working group meeting in the United European Gastroenterology Week 2019 in Barcelona, these concepts were discussed and finalised to be included in our overall guidance document about fecal microbiota transplantation.Results A guidance document for all domains pertaining to stool banking was created. This document includes standard operating manuals for several processes involved with stool banking, such as handling of donor material, storage and donor screening.Conclusion The implementation of fecal microbiota transplantation by stool banks in concordance with our guidance document will enable quality assurance and guarantee the availability of donor feces preparations for patients.
