What is a common contributing factor to peristomal irritant contact dermatitis?

• A. Poor fitting/leaking appliances
• B. Bacterial infection
• C. Excessive moisture alone
• D. Use of stomal paste

Answer: (A)

When peristomal skin is irritated by contact with stomal effluent, the most common contributing factor is a poorly fitting or leaking appliance. Leaks let stool or urine and their enzymes sit on the skin, causing ongoing irritation and inflammation that leads to irritant contact dermatitis. Excessive moisture can make the problem worse, but it’s usually a result of the leak rather than the primary cause. Bacterial infection represents a different issue with potential infection signs, not the typical irritant-driven rash around the stoma. Using stomal paste or barrier products helps seal gaps and protect the skin, so they’re not contributing factors.
