Which statement accurately reflects IPAA eligibility regarding disease extent?

Which statement accurately reflects IPAA eligibility regarding disease extent?

• A. Both GI tract free of disease from mouth to end of small bowel and distal rectum/anal canal disease-free
• B. Only the GI tract needs to be disease-free
• C. Only the distal rectum/anal canal needs to be disease-free
• D. Stomach involvement must be ruled out before IPAA

Answer: (A)

IPAA is chosen only when disease is confined to the colon/rectum and there is no active disease in parts of the GI tract that would be preserved or involved in the pouch. The ileal pouch is formed from the ileum and connected to the anal canal, so any disease present in the upper GI tract (from mouth through the small intestine) or in the distal rectum/anal canal can compromise healing and long-term function. Therefore, the eligibility criterion is that there is no disease anywhere from the mouth through the end of the small bowel and the distal rectum/anal canal must also be disease-free. This ensures a disease-free environment for both the pouch and the anastomosis. In other words, disease outside the colon (including small bowel and anal canal) undermines IPAA suitability, while limiting disease to the colon supports a better surgical outcome.
