Anal fistula: a review of 82 cases

Eighty-two cases of anal fistula have been retrospectively reviewed, and their clinical presentations, pathology, and management presented. Most of the fistulas were primary and, except for the four cases due to tuberculosis, there does not seem to have been any underlying systemic or gastrointestinal causative factor. A preoperative fistulogram is essential in the management of this condition.
