Which condition is a common ileoanal pouch complication affecting the perianal skin?

• A. Perianal skin irritation or breakdown
• B. Pouchitis
• C. Peristomal leakage
• D. Stoma stenosis

Answer: (A)

When an ileal pouch is created, the perianal skin is continually exposed to liquid stool and moisture from the pouch. This constant moisture, along with stool enzymes and frequency of bowel movements, can irritate and macerate the skin, leading to dermatitis, redness, pain, and breakdown around the anal area. This direct skin involvement is why perianal skin irritation or breakdown is a common complication specific to the pouch’s impact on the perianal region. Pouchitis, by contrast, is inflammation of the pouch mucosa itself, not the skin around the anus, so it presents differently. Peristomal leakage and stoma stenosis relate to problems around a stoma, which is not the typical issue encountered with a native ileoanal pouch's perianal skin.
