What is a key wound care consideration for peristomal PG?

• A. Daily aggressive debridement
• B. Cover peristomal skin with powder or a hydrocolloid dressing with an opening to fit the stoma
• C. High-oxygen therapy
• D. No dressings to allow drainage

Answer: (B)

Peristomal pyoderma gangrenosum requires gentle, non-traumatic wound care because even minor handling can trigger or worsen lesions (pathergy). The best approach is to shield the peristomal skin with a dressing that fits around the stoma, protecting it from friction and leakage while allowing a healthy healing environment. A hydrocolloid dressing that is cut with an opening to accommodate the stoma provides this protective barrier, supports moisture management, and minimizes trauma to the surrounding skin. In contrast, aggressive debridement can worsen PG, and leaving the area undressed or using powders around the stoma can irritate the skin; high-oxygen therapy is not a standard local wound-care measure for this condition.
