Stoma Wound Care: Evidence-Based Approach

Initial Wound Care

• The American College of Surgeons recommends daily aseptic wound care with sterile cleansing and breathable dressings for the first week after stoma creation, then transition to simple soap and water cleansing 1-2 times weekly once the site is healed 1, 2
• Daily monitoring and aseptic technique are essential during tract formation, including inspecting the stoma site for bleeding, pain, erythema, induration, leakage, and inflammation 1, 3
• Cleansing with 0.9% sodium chloride, sterile water, or freshly boiled and cooled water is recommended 1, 3
• Applying a sterile Y-dressing under the external fixation plate to absorb drainage and cushion movement is suggested 1, 4
• Using a breathable, skin-friendly, solvent-free dressing over the site is recommended 1, 3
• Never use occlusive dressings as they create moisture that causes skin maceration and infection 1, 2

Alternative First-Week Approach

• Consider glycerin hydrogel or glycogel dressings as a cost-effective alternative to daily standard dressings, with Grade B evidence 2
• Apply the hydrogel dressing the day after stoma placement and change weekly rather than daily during the first 4 weeks 2
• This approach significantly reduces infection scores compared to standard dressings 1, 2

After Initial Healing

• Reduce dressing changes to 1-2 times per week once the stoma tract is formed and the incision healed 2, 3
• Cleanse with simple soap and tap water of drinking quality, and a simple plaster around the wound is sufficient 2, 5
• Alternatively, dressings can be completely omitted and the site left open 2, 3
• Showering, bathing, and swimming are permitted in patients with a stoma, using waterproof dressing for public pools 1, 2

Managing Peristomal Leakage

• Apply zinc oxide-based skin protectants, barrier films, pastes, or creams to prevent breakdown in patients with peristomal leakage 2
• Use foam dressings rather than gauze to lift drainage away from skin while preventing maceration 2
• Verify proper tension between internal and external bolsters without excessive pressure 2
• Address underlying causes of peristomal leakage, including infection, increased abdominal pressure, constipation, tube malposition, or granulation tissue 2

Critical Pitfalls to Avoid

• Excessive tension on the external fixation plate causes tissue ischemia and buried bumper syndrome, maintain 5mm free movement 4, 5
• Insufficient incision size creates pressure necrosis, ensure adequate opening 4
• Occlusive dressings trap moisture and cause maceration, always use breathable materials 1, 2
• Failure to mobilize the tube after healing leads to adhesions, push tube 2-3cm inward and rotate daily after week 1 1, 5
• Inadequate drying after cleansing promotes skin breakdown, thoroughly dry before applying new dressings 4, 5

Special Considerations for High-Risk Patients

• Patients with impaired wound healing require extended intensive care, including daily monitoring beyond 7 days for patients with diabetes, immunosuppression, malnutrition, ascites, or corticosteroid use 2
• Watch for delayed tract formation, which may take up to 14 days instead of 7 3
• Treat local fungal infections with topical antifungals if they develop alongside leakage 2

When to Escalate Care

• Return to daily intensive wound care if increased erythema, purulent drainage, persistent leakage, fever, increased pain, or induration suggesting infection develop after the initial healing period 2, 5
• Difficulty mobilizing the tube or hypergranulation tissue formation also require escalation of care 1, 5

Wound Packing Recommendations for Surgically Repaired Stomas

Guideline Recommendation

• The WSES‑AAST (World Society of Emergency Surgery–American Association for the Surgery of Trauma) guidelines state that an acute abscess should be adequately drained under general anesthesia without a routine requirement for wound packing; this principle is extended to contaminated surgical wounds such as stoma revisions, indicating that routine packing is not indicated. 6

Indications for Packing (Rare Exceptions)

• Packing may be employed only for short‑term hemostatic control when active bleeding cannot be controlled by other measures. 6

Duration and Removal of Packing

• When packing is used for hemostasis, it should be temporary and removed within 24–48 hours to avoid complications. 6

Routine Management Directive

• Packing should never be left in place as a routine wound‑management strategy for surgically repaired stomas; standard open‑healing or appropriate dressings are preferred. 6

All statements are derived from expert consensus within the WSES‑AAST guidelines (World Journal of Emergency Surgery, 2021) 6.
