Autologous Fecal Microbiota Transplantation for Anal Function Recovery After Ileostomy Reversal in Rectal Cancer
Sponsor: Peking University People's Hospital
Summary
This prospective, single-center, single-arm, open-label clinical study aims to evaluate whether autologous fecal microbiota transplantation can improve bowel and anal function after ileostomy reversal in patients with rectal cancer who underwent radical rectal cancer surgery with protective loop ileostomy. Eligible patients will receive autologous fecal microbiota transplantation before ileostomy reversal. The primary outcome is the Low Anterior Resection Syndrome score at 3 months after ileostomy reversal. Secondary outcomes include fecal incontinence score, colonoscopic findings before ileostomy reversal, gut microbiota profiles, inflammatory markers, anorectal manometry, pelvic floor electromyography, and safety outcomes.

Autologous Fecal Microbiota Transplantation
Autologous fecal microbiota transplantation will be prepared from the participant's own fecal material collected from the ileostomy output. Approximately 50 g of fecal material will be mixed with 100 mL sterile normal saline, homogenized, filtered through sterile sieves, and administered slowly into the distal bowel via transanal catheter/enema. The procedure will be performed once weekly at postoperative weeks 8, 9, 10, and 11, for a total of four administrations. Participants will be observed after the procedure according to the study protocol.
