An anorectal abscess has to be deroofed. If, in addition, a fistula is present, it is our policy (in a teaching institution with surgeons in training) to incise it only if easily visualized and situated up to the dentate line. Of 79 anorectal abscesses drainage alone was performed in 55 (group 1) and drainage with fistulatomy in 24 (group 2). One-third of the patients in group 1 needed a secondary fistula operation, but most of the others were free of symptoms after one intervention. In group 2 all but one of the patients were cured by the combined procedure. Incontinence was observed in none.
肛管直肠脓肿必须切开引流。此外，如果存在肛瘘，（在有外科住院医师培训的教学机构）我们的策略是，仅在瘘管易于显露且位于齿状线以下时才进行切开。79例肛管直肠脓肿患者中，55例仅行引流术（第1组），24例行引流及肛瘘切开术（第2组）。第1组三分之一的患者需要二次肛瘘手术，但其他大多数患者一次干预后无症状。第2组除1例患者外，所有患者均通过联合手术治愈。无一例出现失禁。
