Summary
Brief summary
An ileal pouch is formed when the end of the small bowel is used to create a pouch and anastomosed to the anus.
This is required in patients who need removal of all their colon and rectum, most commonly for ulcerative colitis.
The ileal pouch mucosa (or lining) exists in a state of a varying degree of chronic inflammation. When this is more
severe clinical pouchitis develops. Pouchitis is most likely due to an alteration in the microbiota that the ileal
mucosa is exposed to. The microbiota alter due to increased stasis of the contents of the ileal pouch, compared to
ileum in the normal state. From our previous research and that of others, certain bacteria are associated with less
inflammation and certain with more inflammation. We have selected a bacterial culture from previous research that
is associated with a healthy pouch. We have been able to develop this bacterium into a probiotic. We wish to use
this probiotic as a dietary supplement to see if we can improve the health, function and quality of life in ileal pouch
patients.
