This topic is about a person who had an ileostomy surgery and is experiencing persistent blister-like sores on their stoma. These blisters appeared a few months after the surgery, and despite initial thoughts that they were caused by friction, the person is not convinced since nothing seems to be rubbing against the stoma. They are looking for explanations and solutions to this issue.

Here are some helpful insights and advice:

1. The blisters look like cold sores and are located high on the stoma, near the lumen, not at the edge of the appliance. They are painless but concerning.

2. Leakage under the wafer can irritate the surrounding skin and lead to a rash. The person is considering using topical Mylanta to soothe the irritation.

3. Check the size and edges of the wafer opening. If the cut edge is too close or rough, it might nick the stoma and cause small ulcer-like spots. Cutting the hole slightly larger or smoothing the edge can help prevent this, allowing the area to heal naturally.

4. Consider the possibility of product sensitivity. An allergic reaction to a specific barrier, wafer, or adhesive might cause sores or irritation. Switching to a different brand or formulation has helped others with similar issues.

5. To control topical acidity, applying a very thin layer of liquid antacid, like Mylanta, around the stoma can neutralize the acidity of the effluent and help calm or prevent blister-like areas. A diet high in acidic foods might worsen the problem.

6. Some people have experienced large fluid blisters after surgery due to suture pressure. Although the location is different, it highlights that benign pressure-related blisters can occur and usually resolve without long-term issues.
