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.
