[Expert Advice] Certified Wound Specialists Share Best Practices For Managing Peristomal Skin Complications

For individuals living with an ostomy, the skin surrounding the stoma—known as the peristomal skin—is a critical foundation for health, comfort, and quality of life. Unfortunately, peristomal skin complications (PSCs) are remarkably common. Studies indicate that up to 73% of ostomates experience some form of skin breakdown at least once.

Healthy peristomal skin should look and feel exactly like the skin on the rest of your abdomen. When it becomes red, raw, itchy, or painful, it is not just an inconvenience—it compromises the adhesive seal of your pouching system, leading to a frustrating cycle of leaks and worsening skin damage.

To help you break this cycle, we consulted with Certified Wound, Ostomy, and Continence Nurses (CWOCNs) to compile this comprehensive guide on identifying, treating, and preventing peristomal skin complications.

Understanding Peristomal Skin Complications (PSCs)

To effectively manage peristomal skin, it helps to understand why this specific area of the body is so vulnerable to breakdown.

Why Peristomal Skin is Vulnerable

The peristomal area (typically the four-inch radius surrounding the stoma) is subjected to unique environmental stressors:

Chemical exposure: Stoma output (effluent), particularly from ileostomies and urostomies, contains highly corrosive digestive enzymes or acidic urine that rapidly erode the skin barrier.
Mechanical stripping: The regular application and removal of strong medical-grade adhesives can strip away the outer protective layers of the skin (the stratum corneum).
Moisture accumulation: Perspiration and minor effluent leaks can become trapped beneath the barrier, causing maceration (waterlogging of the skin), which weakens its structural integrity.

The Economic and Emotional Impact of PSCs

When peristomal skin breaks down, the adhesive barrier cannot stick properly. This leads to frequent pouch failures, increased product consumption, and rising healthcare costs. Emotionally, the constant fear of public leaks and physical discomfort can lead to social isolation, anxiety, and a significantly reduced quality of life.

Common Types of Peristomal Skin Complications

Correctly identifying the root cause of skin irritation is the first step toward successful treatment. Certified Wound Specialists categorize the most common complications as follows:

Irritant Contact Dermatitis (ICD)

This is the most frequent PSC and occurs when stoma output comes into direct contact with the skin.

Appearance: Red, moist, inflamed skin that matches the exact shape of where the effluent leaked under the barrier.
Common Cause: An improperly sized barrier opening, or leaving a leaking pouch on for too long.

Mechanical Trauma (Skin Stripping)

Mechanical injury occurs when the skin is torn during adhesive removal.

Appearance: Raw, shiny, or bleeding patches of skin that mimic the shape of the adhesive flange.
Common Cause: Pulling the pouch off too quickly, failing to support the skin during removal, or changing the pouching system too frequently.

Candidiasis (Fungal Infection)

The warm, dark, and moist environment beneath an ostomy barrier is an ideal breeding ground for yeast (Candida).

Appearance: A bright red, itchy rash characterized by "satellite lesions"—small, distinct red bumps or pustules spreading outward from the main rash.
Common Cause: Prolonged moisture trapped under the barrier, often exacerbated by sweating or a slow, unnoticed leak.

Allergic Contact Dermatitis

An allergic reaction to the materials in the pouch, barrier, paste, or accessory products.

Appearance: Redness, itching, swelling, or even tiny blisters that align precisely with the shape of the offending product.
Common Cause: Sensitivity to specific adhesives, fragrances, or preservatives in skin prep wipes or adhesive removers.

Pyoderma Gangrenosum (PG)

A rare, painful, inflammatory skin condition often associated with underlying autoimmune diseases like Inflammatory Bowel Disease (IBD).

Appearance: Deep, painful, ulcerated lesions with distinct purple or violaceous borders.
Common Cause: An overactive immune response; this condition is not caused by hygiene or leaks and requires immediate medical intervention.

Expert Best Practices for Assessment and Prevention

Prevention is the absolute gold standard of peristomal skin care. Certified Wound Specialists recommend the following proactive strategies:

The "Look and Feel" Rule

Every time you change your pouching system, perform a self-assessment. Ask yourself:

Is the skin red, purple, or darker than the surrounding skin?
Does the skin feel itchy, warm, or painful?
Is there any moisture, weeping, or bleeding?

If you answer yes to any of these, your skin is compromised, and your pouching routine needs adjustment.

Achieving the Perfect Pouch Fit

Because stomas can shrink, expand, or change shape over time (especially in the first 6 to 8 weeks following surgery), your barrier opening must be measured regularly.

The Goal: The barrier should fit snugly around the base of the stoma, leaving no more than a 1/16th of an inch (1.5 mm) gap.
Flat vs. Convex Barriers: If your stoma is flush with your abdomen, retracted, or sits in a deep skin fold, a flat barrier may allow effluent to seep underneath. A convex barrier applies gentle pressure around the stoma, helping it protrude outward into the pouch and preventing leaks.

Step-by-Step Management Guide for Active Complications

If you are already dealing with irritated, weeping, or broken peristomal skin, follow this clinical protocol designed by wound care experts to heal the skin while maintaining a secure pouch seal.

Step 1: Gentle Cleansing and Prep

Do: Cleanse the peristomal skin using warm water and a soft washcloth or paper towel.
Don't: Use commercial soaps, baby wipes, or body washes. These products often contain oils, moisturizers, or fragrances that leave a residue, preventing your new barrier from sticking.
Dry Thoroughly: Ensure the skin is completely dry before applying any products. Pat dry—never rub.

Step 2: The "Crusting" Technique for Weeping Skin

If your skin is raw, wet, and "weeping" fluid, adhesives will not adhere. Use the crusting technique to create a dry, protective layer over the raw areas:

Apply Stoma Powder: Dust a small amount of stoma protective powder (carboxymethylcellulose/pectin powder) directly onto the raw, wet areas of skin.
Brush Off the Excess: Gently brush away any loose, excess powder. The powder should only stick to the moist, damaged skin.
Seal with Barrier Film: Gently dab (do not rub) an alcohol-free skin barrier spray or wipe over the powdered area. This wets the powder and turns it into a dry, protective crust.
Let It Dry: Allow the area to dry completely (about 30 seconds) before applying your barrier.

Expert Tip: Avoid using alcohol-based skin preps on broken skin, as they will cause a severe, painful stinging sensation.

Step 3: Selecting the Right Accessories

To protect the healing skin and prevent future leaks, consider adding these targeted accessories to your routine:

Molded Barrier Rings/Seals: These alcohol-free, hydrocolloid rings can be stretched and molded around the base of the stoma to fill in uneven contours, skin dips, or scars, creating a customized, leak-proof seal.
Medical Adhesive Removers: Always use a silicone-based, alcohol-free adhesive remover spray or wipe when peeling off your barrier. This dissolves the adhesive bond gently, eliminating mechanical skin stripping.

Peristomal Skin Complications: Quick Reference Guide

When to Consult a Certified Wound, Ostomy, and Continence Nurse (CWOCN)

While many minor skin irritations can be resolved with proper sizing and the crusting technique, certain symptoms require professional clinical evaluation. Contact a CWOCN or your healthcare provider immediately if you experience:

Pain that is severe, burning, or worsening.
Deep ulcers, open sores, or areas of necrotic (black/gray) tissue.
Signs of systemic or localized infection, such as pus, foul odor, or fever.
Skin irritation that does not improve after 2 to 3 pouch changes using the crusting technique.
Constant, unmanageable pouch leaks occurring within 24 to 48 hours of application.

Conclusion

Managing peristomal skin complications requires a proactive combination of correct sizing, gentle skin hygiene, and the right protective accessories. By treating your peristomal skin with the same care and attention as the skin on your face, you can ensure a comfortable, secure pouch fit and regain peace of mind in your daily life.
