Eight patients over age 60 years had sudden onset of acute abdominal pain and rectal bleeding in the absence of prior inflammatory bowel disease. Several improved on medical therapy alone; those who required surgery suffered no recurrence up to 6 years. Although the pathologic specimens on these patients were first considered to represent ulcerative colitis or Crohn's disease, their histories and clinical courses are much more consistent with ischemic colitis. Since there are only a limited number of reactions that the bowel can muster against a host of damaging processes, histologic criteria alone are usually not sufficient to separate ischemic disease of the colon from ulcerative colitis and Crohn's disease. This is also true of radiographic features. Thus the diagnosis of ischemic colitis rests on clinical onset and course after treatment.
8名60岁以上的患者在无既往炎性肠病的情况下突然出现急性腹痛和直肠出血。数名患者仅通过药物治疗病情就有所改善；那些需要手术治疗的患者在长达6年的时间里未复发。尽管这些患者的病理标本最初被认为代表溃疡性结肠炎或克罗恩病，但他们的病史和临床病程与缺血性结肠炎更为相符。由于肠道针对一系列损伤过程所能产生的反应有限，仅靠组织学标准通常不足以将结肠缺血性疾病与溃疡性结肠炎和克罗恩病区分开来。放射学特征也是如此。因此，缺血性结肠炎的诊断取决于临床发病情况及治疗后的病程。
