[Anal abscesses].

Infectious anal abscesses occur at high frequency and are important to understand since they are invariably accompanied by fistulous complications. Knowledge of the anatomy of the anal canal and the distal section of the rectum is important in the choice of therapy. Indeed, treatment varies with the classification of the fistulae. Between 1975 and 1984 the authors treated 105 cases of anal abscesses; a recurrence rate of less than 1 percent was noted.
