Man, I know what you mean! The last thing I wanted was another cut to the butt after having a fissure and an LIS!
But I'm glad I got the fistula fixed - I'm much more comfortable than I was before the fistulotomy. I'm about 11 weeks post-op now and I still bleed a bit during BMs and I can see that the wound is not quite healed, but it looks like it's healing bit by bit, and I don't have any pain - at most some mild discomfort if I have a big poop. During my check-up on Aug 31st, my doc said I was healing well, so I'm not too worried. You mentioned that you had had a rough three months. I imagine that was from the fistula swelling and draining(?) That does suck, but the fistulotomy will take care of that. I'd say in about a month you will be pretty much back to normal. This is a pretty straight-forward surgery, and if your fistula is superficial, then the complication rate is quite low. So I'd say your next op will very likely be a great success story. :D
It is good news that you don't have to starve yourself.

I think you should feel good about finally getting the fistula fixed - soon you will be on your way to complete healing and this whole ordeal will become a distant memory.
