FMT for Patients With IBS With Fecal and Mucosal Microbiota Assessment

Irritable bowel syndrome (IBS) is a common functional bowel disorder of the gastrointestinal tract affecting up to 20 percent of the adolescent and adult populations. It is characterised by abdominal pain, irregular bowel habits, altered stool consistencies and bloating, and is associated with impaired quality of life. IBS can be categorised into diarrhoea predominant type (IBS-D), constipation predominant type (IBS-C), and mixed type (IBS-M). Fecal microbiota transplantation (FMT) defined as infusion of feces from healthy donors to affected subjects has shown impressive results with high cure rates in patients with recurrent clostridium difficile infections. The investigators propose a randomised, placebo-controlled trial of FMT in patients with IBS.
