[Out-patient treatment of periproctitic abscesses (author's transl)].

A total of 237 patients were treated over a period of five years for anorectal abscesses. Wide circular opening with removal of all purulent foci and necroses from outside had been preferred, because almost only "late forms" of anorectal inflammatory processes (perianal and ischiorectal abscesses) were seen. Sphincterotomy was possible in only a few patients. Postoperative fistulae occurred in 14% of the patients.
