Summary

Ileal pouch-related adenocarcinoma remains a rarity; thus, guidelines on treatment are currently lacking. We present this case of a 54-year-old man who underwent restorative proctocolectomy with stapled ileal pouch–anal anastomosis formation for familial adenomatous polyposis during the 1980s. Despite undergoing annual surveillance endoscopy, the patient was noted to be anaemic and passing fresh blood per anus. Endoscopy and radiological investigation revealed the presence of a pouch-related adenocarcinoma. This was subsequently treated with short-course radiotherapy and pouch excision. The patient remains well until now and will follow six-monthly surveillance protocols with a transition to annual surveillance after 2 years.
