Participants will be given FMT through oral capsules or nasojejunal tube once a month. After three-time treatment, participants were followed up for three months. Participants complete specific scales to assess improvement in symptoms, emotion and quality of life. Besides, they report adverse effects and collect fecal samples at each visit.
This prospective, single-arm interventional study aims to evaluate efficacy and safety of fecal microbiota transplantation in refractory IBS patients. Patients meeting the inclusion and exclusion criteria will provide written informed consent and receive FMT from healthy donors for three times. The administration methods include taking oral capsule or delivering microbiota suspension into the duodenum via nasojejunal tube. The patients receive treatment once a month and will be followed up for 3 months. Improvement in IBS symptoms, emotion and quality of life were assessed through IBS symptom severity scale (IBS-SSS), Gastrointestinal symptom rating scale (GSRS), IBS-Global Assessment of Improvement (IBS-GAI), Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS) and IBS-Quality of Life (IBS-QoL) respectively. Patients were asked to complete these scales and collect fecal samples at baseline, post-FMT and at 1, 2, 3 and 4 months after FMT. Primary endpoints were improvement in IBS-SSS score and global symptoms after three-time FMT. Secondary endpoints include Change in GSRS score, improvement in emotion and quality of life at post-FMT, 1 and 6 months, as well as change in fecal microbiota composition.

| Change from baseline IBS symptom severity scale (IBS-SSS) score at 9 weeks | IBS symptom severity scale (IBS-SSS) is used to evaluate change in IBS symptoms, with a score ranging from 0 to 500. Higher score means severer IBS symptom. Change in IBS-SSS score is obtained by evaluating the scale at baseline and 9 weeks (after three-time FMT). | at baseline and 9 weeks |
| Response rate at 9 weeks | Investigator ask participants a single question, "Compared to the way you felt before you entered the study, have you IBS symptoms over the past 7 days been: 1)"Substantially Worse"; 2)"Moderately Worse"; 3) Slightly Worse; 4)"No Change"; 5) Slightly Improved"; 6) Moderately Improved"; 7) Substantially Improved". Responder is defined as participants who report "moderately improved" or "substantially improved". | at 9 weeks |
| Measure | Description | Time Frame |

| Change from baseline IBS symptom severity scale (IBS-SSS) score at 1 week, 1 month and 6 months | IBS symptom severity scale (IBS-SSS) is used to evaluate change in IBS symptoms, with a score ranging from 0 to 500. Higher score means severer IBS symptom. Change in IBS-SSS score is obtained by evaluating the scale at baseline and at 1 week (after first FMT), 1 month (three weeks after first FMT), and 6 months (4 months after three-time FMT). |

| at baseline, 1 week, 1 month and 6 months |
| Change from baseline Gastrointestinal Symptom Rating Scale (GSRS) score at 1 week, 1 month, 9 weeks and 6 months | Gastrointestinal symptom rating scale (GSRS) is used to evaluate change in gastrointestinal symptoms, with a score ranging from 15 to 105. Higher score means severer gastrointestinal symptoms. Change in IBS-SSS score is obtained by evaluating the scale at baseline, 1 week (after first FMT), 1 month (three weeks after first FMT), 9 weeks (after three-time FMT) and 6 months (4 months after three-time FMT). | at baseline, 1 week, 1 month, 9 weeks and 6 months |
| Change from baseline IBS-Quality of Life (IBS-QoL) score at 1 month, 3 months and 6 months | IBS-Quality of Life (IBS-QoL) is a specific scale used to evaluate change in quality of life, with a score ranging from 0 to 100. Higher score indicates worse quality of life. Change in IBS-QoL score is obtained by evaluating the scale at baseline, 1 month (three weeks after first FMT), 3 months (three weeks after third FMT) and 6 months (4 months after three-time FMT). An over-14-point reduction is considered a significant improvement in quality of life. | at baseline, 1 month, 3months and 6 months |
| Change from baseline Self-rating Anxiety Scale (SAS) score at 1 month, 3 months and 6 months | Self-rating Anxiety Scale (SAS) is used to evaluate change in IBS-related anxiety, with a score ranging from 25 to 100. Higher score indicates higher level of anxiety. Change in SAS score is obtained by evaluating the scale at baseline, 1 month (three weeks after first FMT), 3 months (three weeks after third FMT) and 6 months (4 months after three-time FMT). | at baseline, 1 month, 3months and 6 months |
| Change from baseline Self-rating Depression Scale (SDS) score at 1 month, 3 months and 6 months | Self-rating Depression Scale (SDS) is used to evaluate change in IBS-related depression, with a score ranging from 25 to 100.
