Is it possible for fissures to lead to abscess and then fistula? Probably
Do they usually? Probably not
One problem is proving causation. Just because someone has a fissure and then gets an abscess, it doesn't mean the fissure led to the abscess, but it doesn't rule that possibility out either.
Just like causation can't be determined to say that if you have hemorrhoids it will lead to abscess and potentially fistula.
Every case is individual and needs to be evaluated individually.
