Can a stool transplant calm an inflamed pouch?
NCT ID NCT03545386
First seen Aug 12, 2026 · Last updated Aug 13, 2026 · Updated 1 time
Summary
This study tests whether giving healthy donor stool through an enema once a week for six weeks can help people with active pouchitis—a condition where the surgically created intestinal pouch becomes inflamed. Half the participants receive the real transplant, while the other half get a placebo enema. The goal is to see if the treatment can reduce symptoms and inflammation enough to achieve remission.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Fecal microbiota transplantation (donor stool given as an enema)
- What this could lead to
- If it works, this could offer a new, non-drug way to calm pouchitis and help people avoid long-term antibiotics or surgery.
- What could go wrong
- This is a small, early-stage trial, so results may not hold up in larger groups. The enema procedure may be uncomfortable, and there is a small risk of infection from donor stool.
