Clinical Trial Summary

Small intestinal bacterial overgrowth (SIBO) is defined as the presence of excessive numbers of bacteria in the small bowel causing gastrointestinal (GI) symptoms. These bacteria are usually coliforms, which are typically found in the colon and include predominantly Gram-negative aerobic and anaerobic species that ferment carbohydrates producing gas .Fecal Microbiota Transplantation (FMT) is a therapeutic method to transplant the microbiota from the feces of healthy people into the intestinal tract of patients. To explore the overall efficacy and safety of FMT in the treatment of SIBO.

Intervention

Procedure:
• Fecal microbiota transplantation
Fecal microbiota transplantation (FMT) achieves the purpose of treating intestinal and extra-intestinal diseases by transplanting the functional microbes in the feces of healthy people into the patient's intestine through the upper or lower alimentary tract routes to rebuild the patient's intestinal microbiota.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Incidence of adverse events (Assessing the safety of FMT in patients with SIBO)	Document adverse events related to FMT that occurred during the study, including their frequency and severity.	7 days, 1 month
Primary	Number of Patients with gastrointestinal symptom scores	The efficacy of FMT in SIBO patients was evaluated according to the scores of gastrointestinal symptoms before and after treatment. Patients with gastrointestinal symptom scores, including some of the abdominal symptoms and defecation situation, we can according to this questionnaire to assess patients with abdominal symptoms and defecate on the improvement of their situation.	7 days, 1 month
Primary	Investigating the impact of FMT on the colonic and small intestinal microbiota.	For patients before and after the FMT feces and small intestinal juice samples 16 s rRNA sequencing, compare the difference between before and after the FMT feces and bacteria in the intestinal flora of diversity, species composition belong. The changes of commensal bacteria, opportunistic pathogens and pathogenic bacteria in feces and small intestinal fluid after FMT were compared.	7 days, 1 month
