Irritable bowel syndrome (IBS) is a chronic gastrointestinal disease characterized by abdominal discomfort and bloating, diarrhea, and/or constipation. Fecal microbiota transplantation (FMT) is transferring the fecal bacteria and other microorganisms from a healthy person to another. We performed this systematic review and meta-analysis to assess the efficacy of FMT in treating IBS patients. We searched Scopus, PubMed, Cochrane, and Web of Science databases through June 2021 using relevant key words. We included 19 studies. Fecal microbiota transplantation was significantly superior to placebo in IBS quality of life after 4 weeks (mean difference [MD] = 7.47, 95% confidence interval [CI]: 2.05-12.89, p = .04), 12 weeks (MD = 9.99, 95% CI: 5.78-14.19, p.00001), and 24 weeks (MD = 8.49, 95% CI: 0.47-16.52, p = .04), with no difference regarding IBS improvement symptoms and the IBS Severity Scoring System (SSS). Single-arm analysis revealed that the incidence of improvement of IBS symptoms was 57.8% (45.6%-69.9%) with reduction in IBS-SSS (MD = -74, 95% CI: -101.7 to -46.3). Fecal microbiota transplantation was superior to placebo in improving quality of life after 4, 12, and 24 weeks. Also, FMT improved IBS symptoms and reduced the IBS-SSS score. However, no deference was detected between FMT and placebo in IBS-SSS score and IBS symptoms improvement. |
