I used gauze and tape. I bought this gauze that had a plastic lining on one side, and it taped it reallllllllll good so it didn't leak. I had good days when I only had to change the dressing twice, and bad days when I was changing the dressing every hour. What is happening is the fistula "waxes" over, you will notice little to no drainage, then when it breaks through again it's a ton of drainage. I had to deal with this for over a year. Good luck! Have you considered surgery to try to repair it?
