Primary

MeasureTime frame
ompare the efficacy of fecal microbiota transplantation using oral fecal capsules versus fecal microbiota transplantation delivered via colonoscopy in the treatment of irritable bowel syndrome. 12 weeks Change in IBS-SSS from baseline to post-treatment

Secondary

MeasureTime frame
To compare irritable bowel syndrome related quality of life 12 weeks measured by the Irritable Bowel Syndrome Quality of Life questionnaire (IBS-QOL), before and after treatment.,evaluate the adverse events associated with fecal microbiota transplantation administered via oral fecal capsules and via colonoscopy. 2 weeks Record adverse event ,investigate changes in the gut microbiota before and after fecal microbiota transplantation in patients with irritable bowel syndrome 12 weeks Stool fecal microbiota analyze
