Thanks to a very kind and helpful stoma nurse I have discovered Urgoplaque (don't know the english name but it is the same stuff that is sold in drugstores for blisters except that this is large patches), a cortcoidal patch that can be cut to size to cover the area around the stoma. It stays in place for up to 3 or 4 days depending on the liquid output around it and protects the skin.
For the moment I am using it to 'hold down' the folley in place instead of tape and it has saved my skin!
I tape my stoma cover over it when needed and gently pull off the tape so as not to pull the patch off too...wonderful! It has been in place for 1 month ( I change it whenever needed) and I no longer have 'burn' or scabby painful skin. One less pain is fine with me!
She suggested that I cut a hole in the middle and place it around the stoma to prtect the whole area but I am just fine with it holding the folley down. I intubate beside the folley and only use it as a guide or an emergency outlet ( too small otherwise).
It sticks through showers and baths and only comes unglued if I leak down the folley.
worth a try for any of you who are suffering.

this is what I found when I googled:
URGO ALGOPLAQUE FILM
One site said it was prescription.

I have used Calmoseptine which has been very successful.

that is it..sorry for the wrong reference.
It really works although unsticks when wet although not in the shower or bath (only when i leak under it!)
It saves my skin like you would not believe;
Do not know if it has any sideeffects but over the short term it is great...but yes, you need a script...i get 16 per box and cut them in half for my needs...average change every other day or every third other than bad leakage days...like today...still..it is worth it!
