Fistula After Colostomy - Experiences and Advice?

Has anyone on here developed a fistula from your rectal stump and it drained through your incision?

Hi, I developed a fistula after my operation. It was about 2 inches away from my stoma, behind my belly button. I had an incision about 30 cm down the middle of my belly for the surgery. In the beginning, it used to leak liquid waste out of my belly button as well as my stoma. I even passed wind through it for a couple of weeks (very strange to trump from your belly button). I wore a little ileostomy pouch over the top of it, and luckily it healed after about 6-7 weeks. I feel I'm going to be prone now to getting a hernia in this area.
