Liz, my fistula was an anal fistula. My surgeon took the wait and see if it heals on its own stance for a bit. It didn't heal of course. We then decided on putting a stitch in it.( Beyond the way that sounds I've no idea how that's done) That was done about 19 months ago, had my take down a month after that, and haven't had it come back. I really cannot even remember having any symptoms with mine. I just know that when they did the barium x-ray, they found it. Now for gas, try laying on your side with your one knee bent, or on all fours. Don't force it, just let it happen. I take alot of Beano. Unfortunately ,it only works for what it works for. Gas for us, especially with new pouch can be horrendous. It does get better, just be kind with yourself. Hope this helped you a little bit anyway.
