In a series of 360 patients with Crohn's disease 18% have developed a complication of abscess and/or fistula. Both complications can be spontaneous but more commonly occur in patients who have had a previous operation. There is a high incidence of fistula after laparotomy without resection of diseased bowel. Simple drainage of an abscess is usually followed by a fistula and fistulae do not close spontaneously. The optimal surgical treatment for fistula and for deep abscess is excision in continuity with the diseased segment of intestine.
在一组360例克罗恩病患者中，18%出现了脓肿和/或瘘管并发症。这两种并发症都可能自发出现，但更常见于既往接受过手术的患者。未切除病变肠段的剖腹手术后瘘管发生率很高。脓肿单纯引流后通常会形成瘘管，且瘘管不会自行闭合。瘘管和深部脓肿的最佳手术治疗方法是将病变肠段连续切除。
