Anorectal abscess-fistulae

Abstract

Anal abscess-fistulae have a tendency to recur based on variations in anatomic configuration and complexities of operative treatment and problematic postoperative healing. A classification of superficial, simple, complex, and recurrent fistulae was used to track outcome. Recurrence rates are substantially higher for those fistulae classified as complex. The reasons for this are discussed in this article.
