Hope you don't mind me joining in. I too, have a similar fistula. I don't think I'd consider the seton, as it does not sound comfortable at all. However, I am trying fasting with clear liquids so that the pouch can have a rest. I tried this before (for 20 days) and it healed all by itself. This time I am also trying using baking soda/water (as a douche) to neutralize the acidic drainage that is coming out of the vagina. This is not a fun thing to have. No intercourse either. This sucks but I'm determined to have this heal up by itself as it did before. Funny, this time, I did not have an abcess first. Any comments or suggestions to help all of us is appreciated. I've had my pouch since 1986 because of colitis.
