The purpose of these pages is to provide clinicians with the ability to calculate the risk of ileal pouch failure for patients undergoing restorative proctocolectomy. The Cleveland Clinic Ileal Pouch Failure model is based a population of 1965 patients undergoing ileal pouch surgery between 1983 and 2001 (24).

There is also a wealth of general information on risk prediction in surgery - this area of the site is constantly being updated and it is worth checking back on a regular basis. The service described above is provided free of charge with no liability attached (see disclaimer).
