Stomas and Wound Management: Peristomal Dermatology

Mucocutaneous separation can occur in the early postoperative period. This does not usually necessitate surgical intervention, but does require wound care interventions along with pouching. A common and effective treatment is to fill the defect left from the separation with stoma powder and then use stoma paste to “caulk” the open defect.
