Yep, I had 4 setons placed in them July 24th. I have 2 fistula with branches. I had the drains in for 4 months, I had the seton healing checked a couple of times before surgery was approved. (My fistulas were more than 5 years old, so complex to heal).
If you haven't met with your surgeon in a couple months, I'd email them and make an appointment. From what I've read setons can be in for 6 months.
I had the 2nd surgery (fistulotomy) last week, 4 long months with setons. The channels are still draining but I feel much better than I did during surgery 1.
I won't know for 3 months if the surgery was successful or if I need a 3rd. From what I was told, the surgery has a 60% success rate with healed fistulas.
It's a long journey, I hope you're able to get the setons removed soon!
