I have a fistula going from my rectum to my vagina. its from a surgery to help with my crohns disease. they removed part of my colon and redirected my stool through a hole in my abdomen called a stoma. because there is no stool passing through my rectum, its safe for the fistula to be connected to my vagina. lindsay didn't mention that stool can pass through those connections and get into the vagina which can cause infections.
