Uneven Skin Around a Retracted Stoma: How to Fill Gaps
Quick Answer
If a retracted stoma keeps leaking from one small area, the problem may not be the whole pouching system. It may be a local gap: one dip, crease, scar line, or lower side around the stoma where output can travel under the barrier.
The goal is not to add more material everywhere. The goal is to find the exact low spot and fill it with the smallest useful amount of barrier ring, barrier strip, or ostomy paste.
This guide focuses on local filling, not general leak troubleshooting or convex pressure. If you are still unsure where the leak starts, first identify the leak pattern. If the issue is pressure from convexity or a belt, review that separately.
First Check: Is It an Uneven Contour or a Wound?
Before filling a dip or crease, make sure you are not trying to “fill over” damaged skin.
| What You See | More Likely | What to Do |
|---|---|---|
| Shallow dip beside the stoma | Uneven contour | May need local filling |
| Narrow crease or scar line | Uneven contour | Map the exact location |
| Fold appears only when sitting | Dynamic contour | Check seated position |
| Open, bleeding, draining area | Skin damage or wound | Contact an ostomy nurse |
| Increasing pain or deeper skin loss | Not routine filling issue | Seek clinical advice |
Do not treat open, bleeding, draining, or painful skin as a simple contour problem. If leakage or irritation lasts for a few days, MSKCC advises contacting the healthcare provider’s office to connect with a WOC nurse.
Quick Decision: What Shape Is the Gap?
Start with the shape of the uneven area.
| If the Gap Looks Like This | Consider | Avoid |
|---|---|---|
| One small dip | Small wedge | Full second ring by default |
| One lower side | Crescent shape | Thick material all around |
| Narrow crease or scar line | Thin strip or small paste line | Large bulky layer |
| Oval or uneven stoma base | Oval or asymmetrical ring | Round ring that leaves side gaps |
| Deep fold | Professional fit review | Repeated accessory stacking |
| Open or painful skin | Clinical assessment | Filling it like a normal contour |
A small, targeted fill usually works better than building a thick “wall” around the whole stoma.
Find the Exact Gap Before Adding Material
Use quick clues. Do not overcomplicate this step.
| Check | What to Look For |
|---|---|
| Used barrier | Softened, whitened, or undermined area |
| Leak direction | Same clock position each time |
| Skin surface | Dip, crease, scar, or one lower side |
| Sitting position | Fold or gap that appears only when seated |
Use clock positions if helpful. For example, “leaks start at 6 o’clock” or “skin is red at 4–5 o’clock.” This makes the next adjustment more precise.
Choose the Filling Material by Gap Shape
Different accessories solve different shapes. UOAA describes flat barrier rings as helpful for uneven skin surfaces and gaps, barrier strips as useful for filling creases, and ostomy paste as a seal around the skin barrier opening. UOAA also notes that paste is not an adhesive or glue, and too much paste may interfere with a good pouch seal.
| Material | Best For | Be Careful If |
|---|---|---|
| Moldable barrier ring | Broader unevenness or irregular stoma base | A full ring adds unnecessary height |
| Piece of ring or barrier strip | One low area, scar line, or one clock-position leak | Edges may need tapering |
| Ostomy paste | Thin shallow crease or narrow gap | Paste is filler, not glue |
| Convex fit review | Retraction or folds need pressure support | Extra filling may change pressure location |
Follow product-specific instructions. Not all rings, strips, or pastes are meant to be stretched, cut, layered, or handled in the same way.
Shape the Seal With Less Material
Shape 1: Small Wedge for One Depression
Best for:
One small dip where leaks repeatedly begin.
How to shape:
Tear or cut a small piece of barrier ring. Flatten one edge so it blends into the skin or barrier. Place the thicker part into the low area.
Watch out:
Do not create a raised edge beside the depression. A sharp edge can become a new leak path.
Shape 2: Crescent for One Lower Side
Best for:
One side of the stoma sits lower than the other.
How to shape:
Shape a small curved piece of ring into a crescent. Place it along the lower side, not all the way around unless needed.
Watch out:
Avoid making the entire seal bulky. Too much height can affect how the barrier sits.
Shape 3: Thin Strip for a Narrow Crease
Best for:
A narrow crease, scar line, or small channel.
How to shape:
Use a thin piece of barrier strip, ring, or paste depending on the crease size and product instructions. Keep it narrow and smooth.
Watch out:
Do not overfill the crease. The goal is to soften the gap, not build a ridge.
Shape 4: Oval or Asymmetrical Ring
Best for:
An oval stoma base or uneven opening where a round ring leaves side gaps.
How to shape:
Gently mold the ring into the shape of the stoma base. Add thickness only where the skin is lower.
Watch out:
Do not overstretch the ring. UOAA notes that some rings may be stretched slightly to fit the stoma, but users should not overstretch them.
Apply the Material to the Skin or Barrier
Some people apply filling material directly to the skin. Others apply it to the back of the skin barrier. UOAA notes that some barrier rings may be applied to clean, dry skin or to the back side of the skin barrier.
| Apply Material To | May Help When | Watch Out |
|---|---|---|
| Skin | You need to see the exact depression | Harder if output starts quickly |
| Barrier | You want material centered around the opening | May miss the exact skin crease |
A practical approach is to choose the method that helps you place the material most accurately and cleanly. If output starts quickly, pre-shaping material on the barrier may be easier. If the dip is hard to locate, placing material on the skin may help you target it better.
Check Whether You Used the Right Amount
The right amount should improve the seal without creating a new problem.
| Result | What It May Mean | Next Step |
|---|---|---|
| Leak channel improves | Amount may be close | Keep tracking |
| Leak continues in same place | Too little or wrong placement | Reposition or add slightly, locally |
| Leak moves beside filled area | Edge may be too abrupt | Taper the edge |
| Whole barrier lifts | Too much material | Reduce thickness |
| New pressure mark appears | Too much pressure or bulk | Stop and reassess |
| Material swells toward stoma | Placement may be too close | Move outward or adjust opening |
A better seal should not require stacking paste, rings, strips, convexity, and belt pressure all at once.
What to Change When the Seal Still Leaks
Use the result to decide the next small adjustment.
| What Happens | Possible Reason | Try Next |
|---|---|---|
| Same leak continues | Gap not filled enough or wrong spot | Recheck clock position |
| Leak moves to edge of material | Material edge too sharp | Smooth or taper edge |
| Barrier feels raised | Too much thickness | Use less material |
| Convex barrier feels different | Filler changed pressure location | Ask for fit review |
| Skin becomes sore | Leakage, pressure, or irritation | Stop repeated layering and seek help |
If you already use a convex barrier, be cautious with extra ring thickness. Too much material under the convex area may change where pressure lands. If convexity feels less effective or causes new pain after adding filler, stop repeated layering and ask for a fit review.
Adjust One Detail at a Time
Keep this simple. Change one thing, then watch what happens.
Change one detail at a time, such as:
- Gap location
- Material type
- Material thickness
- Shape
- Edge tapering
- Skin vs barrier application
- Wear time
Avoid changing the ring, paste, convexity, belt tension, and pouch type all at once. If several things change together, it becomes harder to know what helped.
Do and Avoid
| Do | Avoid |
|---|---|
| Identify the exact low area first | Adding a full second ring by default |
| Use clock position | Covering or crowding the stoma opening |
| Use the smallest useful amount | Filling open or bleeding skin like a contour |
| Taper edges | Creating a raised ridge |
| Keep the opening clear | Layering too many accessories at once |
| Ask for help if skin worsens | Wearing a leaking system to extend wear time |
When to Ask an Ostomy Nurse for Help
Ask for a fit review soon if:
- The seal is not dependable.
- You need large amounts of filling material.
- The leak keeps moving.
- A deep fold or scar line is involved.
- A convex barrier plus filler causes pain.
- Skin stays red, wet, sore, or broken.
- You cannot tell whether the issue is a gap, pressure, or product fit.
- Leakage or irritation lasts for more than a few days.
Seek prompt medical advice if:
- The area is open, bleeding, draining, or very painful.
- Skin damage rapidly worsens.
- The stoma changes color, size, or function.
- You have no output with nausea, vomiting, cramps, or abdominal swelling.
- The pouching system cannot stay attached long enough to protect the skin.
WOCN’s clinician guide recommends referral when the cause of a peristomal skin problem is unclear, current management is not improving the skin, or a reliable pouch seal cannot be maintained.
Frequently Asked Questions (FAQ)
Q1: Should I use a full barrier ring for uneven skin?
Sometimes, but not always. A full ring may help broader unevenness. If only one small dip is leaking, a small shaped piece may be enough and may add less bulk.
Q2: Is ostomy paste the same as glue?
No. Ostomy paste is not glue. UOAA describes paste as a seal around the skin barrier opening and notes that too much paste may interfere with a good pouch seal.
Q3: Can I cut or reshape a barrier ring?
Many barrier rings are moldable, and some may be stretched or shaped, but product instructions vary. Follow the product’s instructions and avoid overstretching.
Q4: Should the filling material touch the stoma?
It should not crowd, rub, or block the stoma opening. If material swells toward the stoma or output cannot enter the pouch easily, reassess the placement and opening.
Q5: Why does the leak move after I fill one gap?
The material may have blocked the original path but created a new edge or ridge. Try tapering the edge or using less material.
Q6: Can filler replace a convex barrier?
Usually, no. Filler helps smooth local gaps. Convexity provides pressure and shape around the stoma area. If retraction or folds need pressure support, ask an ostomy nurse whether convexity should be reviewed.
Q7: When should I stop trying to fix it myself?
Stop repeated adjustments and ask for help if skin is open, bleeding, painful, worsening, or if leaks continue despite careful small changes.
