Which condition is a commonly recognized complication of an ileoanal pouch?

• A. Perianal skin irritation or breakdown
• B. Prolapse
• C. Perineal abscess
• D. Pouchitis

Answer: (D)

After an ileoanal pouch is created, the most commonly recognized issue affecting the pouch itself is inflammation of the pouch mucosa, known as pouchitis. This condition arises from changes in the pouch environment and bacterial balance after surgery and tends to present with symptoms such as increased stool frequency, urgency, cramping, and sometimes fever or malaise. Endoscopic evidence of mucosal inflammation supports the diagnosis, and antibiotics often lead to improvement, underscoring its inflammatory nature.

Perianal skin irritation or breakdown, prolapse, and perineal abscess can occur with an ileoanal pouch, but they are not as consistently seen or as characteristic as pouchitis. Pouchitis specifically reflects a localized inflammatory process of the pouch itself, making it the best answer.
