Which of the following is NOT a complication related to MC separation?

• A. Stomal edema
• B. Stomal retraction
• C. Stomal stenosis
• D. Stoma necrosis

Answer: (A)

Understanding mucocutaneous separation means focusing on problems that stem from a loss of secure attachment between the bowel mucosa and the skin around the stoma. When this seal fails, tissues may pull back or the stoma can become dislodged, leading to issues with function, skin breakdown, and healing.

Stomal retraction can occur when the stoma sinks back into the abdominal wall, a problem that can be worsened by poor mucocutaneous healing and tension at the junction. Stomal stenosis develops from scar tissue formation that narrows the lumen, which can be aggravated by abnormal healing at the mucocutaneous interface. Stoma necrosis is tied to compromised blood supply and tissue viability at the stoma site, a serious consequence that can be related to poor healing at the mucocutaneous junction.

Stomal edema, while common after stoma creation as part of the normal postoperative swelling, is not a direct complication of mucocutaneous separation itself. It reflects general tissue edema rather than separation at the mucocutaneous interface, and it typically resolves with time and standard care.
