What Can We Say About This Issue?
• Development of Dysplasia/Carcinoma is a rare event.
• Likely risk not greater than in ileal mucosa after
  proctocolectomy ( > 17 reported cases of Ileostomy
  Adenocarcinoma).
• Selected patients may be at more risk.
• Some form of organized follow-up should be instituted
  for the pouch and the residual mucosa and ATZ.
• Mucosectomy does not absolutely protect.
