I had two setons inserted and then when they didn’t do their job adequately and the abscess kept spreading, I had a mushroom drain inserted.
I think it depends on the ‘type’ of seton you have inserted and the job it is in there ‘to do’. I had one which was a ‘cutting’ seton, which ‘laid open’ the piece of skin between my bottom and the abscess….. Once this skin was laid open it could heal properly….. it was taken out when my mushroom drain was inserted (after being in for about a month)
The 2nd seton is still in there, and my surgeon has told me it will come out eventually, but I am currently waiting for remicade and applying for it – so after a couple of treatments he said it will be taken out and we will see what happens. My 2nd seton goes into my tailbone and around through into my bottom, I didn’t even know I had a fistula there, but apparently so. I was only aware of the abscess – not the 2nd fistula.
