What describes mucocutaneous separation?

• A. Separation of intestinal mucosa in the lumen
• B. Separation at the mucocutaneous junction
• C. Separation of abdominal muscles
• D. Separation of skin from subcutaneous tissue

Answer: (B)

Mucocutaneous separation describes a breakdown at the boundary where the intestinal mucosa meets the skin around the stoma. It means the mucosal edge has pulled away from the peristomal skin, creating a gap that can leak stool under the barrier and irritate or damage the skin. This is about the interface at the mucocutaneous junction, not about mucosa inside the intestinal lumen, not about abdominal muscles, and not about skin detaching from subcutaneous tissue. Clinically you may see exposed mucosa at the stoma edge, increasing leakage, and peristomal skin irritation. Management focuses on protecting the skin, ensuring a secure appliance fit without traction, and addressing contributing factors (infection, inflammation, nutrition, or need for surgical assessment if the separation persists).
