Which description best defines MCJ separation?

• A. Occurs when a stoma completely or partially separates from the skin
• B. A stoma that prolapses
• C. Stoma is infected
• D. Stoma is blocked

Answer: (A)

MCJ separation describes a break at the mucocutaneous junction, the interface where the stoma’s mucosa meets the skin. This is best captured by describing a stoma that completely or partially separates from the skin. When the stoma pulls away from the skin, a gap forms around the stoma that compromises the seal of the appliance, increasing leakage onto the surrounding skin and risking peristomal skin irritation or dermatitis. This differs from a prolapsed stoma (which means the stoma protrudes outward), an infected stoma (redness, warmth, drainage, fever), or a blocked stoma (little or no output with possible abdominal distension). Management centers on protecting the skin and repairing the seal: re-evaluating the stoma size, adjusting the flange and barrier with paste or rings as needed, and seeking input from an ostomy nurse or surgeon if separation persists, since persistent MCJ separation may require surgical revision.
