[Pathogenetic treatment of chronic paraproctitis].

Operations were performed on 865 patients for pararectal fistulas. The fistulas occurred after injury in 18 patients, histological examination revealed fistulous form of Crohn's disease in 14 patients, 12 patients had tuberculous paraproctitis. The late-term results of surgical treatment of chronic paraproctitis were studied in 560 patients according to the presence of concomitant hemorrhoids. One-stage excision of the fistula and hemorrhoidectomy was conducted in 329 patients. The fistula recurred in 1.3% of cases. Hemorrhoidectomy was not undertaken in 231 patients; a recurrence of fistula occurred in 6.1%. Therefore, to prevent recurrences of pararectal fistulas existing hemorrhoids must also be removed.
