Insights into the role of fecal microbiota transplantation for the treatment of inflammatory bowel disease

Fecal microbiota transplantation (FMT) has changed the treatment landscape of Clostridium difficile infection (CDI). Emerging evidence has shown that FMT can also be an effective and safe treatment strategy in CDI with underlying inflammatory bowel disease (IBD). Recently, randomized controlled trials of FMT in ulcerative colitis support its expanding role in restoring gut homeostasis in this disease. However, heterogeneous study designs leave several questions yet to be answered, including how to best position this novel therapy in the treatment approach of Crohn’s disease and pouchitis. Additional studies are needed to validate whether FMT can assume a complementary role in the standard treatment of IBD
