Hi friendlyfeline. I have not experienced your type of surgery, but just wanted to let you know it sounds like my fistula is in the same place as yours, with the external
opening about
the same area. Mine popped on its own about
a year ago, and then a couple times since then. It's about
a year old now. I have a jpouch - my doctor does not recommend surgery or the heavy-duty drugs, and I'm glad of that, but tired of dealing with this thing: no intimacy, off-and-on drainage, fatigue, frustration, etc. And I have to add self-pity, since I've been on a "why me" kick lately.
I am so sorry you are going through this difficult ordeal - I hope and pray for a swift and permanent recovery for you.
