What is a stoma granuloma?

One of the most common reasons ostomates request a review appointment is that they have noticed some bleeding around their stoma. One of the most common reasons for this is a little thing called a granuloma, this usually occurs at the junction of where the stoma joins onto the skin. 

What does a granuloma look like?

Granulomas are small, red, raised areas on or around the stoma. They develop as a result of over-healing of damaged skin or the stoma surface, possibly due to friction from the bag. Some, but not all, stoma granulomas can cause bleeding and discomfort.

Treatment of a granuloma

The first thing the nurse will do for you is measure the template of your bag that your cutting or have already got pre-cut. It is really important that the bag is as neat a size as possible to the stoma as the more contact with the mucocutaneous junction or the peristomal skin can develop other problems.

If you are diagnosed that you do have a granuloma you will be wondering what the best treatment for this is. According to the most recent guidelines for the stoma care nurses the first line of treatment would be using a silver nitrate pencil. What the nurse will do is just press the pencil down on the granuloma causing it to reduce in size. You will need to go back to the hospital for around 4 weeks, 1 day each week to have the treatment repeated.

Another tip that works well is once the nurse has treated the granuloma, put on a seal or a washer over the top of the treatment area helping to press down on the granuloma.

There is no real way to prevent granulomas occurring. They can re occur again even though they have been treated.
