Defining pouch failure in IPAA studies

What is known

• One study frames the outcome in terms of salvage: successful pouch salvage was defined as an intact, functioning pouch after resolution of the problem, with at least six months follow-up and good-to-excellent satisfaction and continence. ¹
• Reported pouch failure rates after IPAA are cited as ranging from about 5% to 18%. ²

What is unknown / caveats

• The retrieved excerpts do not give an explicit, standardized definition of pouch failure used across most IPAA outcome studies.
• The excerpts note little consistency across studies regarding factors associated with failure.
