Four patients with massive gastrointestinal hemorrhage were found to have Crohn's ileitis. This prompted a five-year chart review of consecutive admissions for Crohn's enteritis; 60 patients were found whose disease was limited to the distal part of the ileum (and rarely the proximal part of the cecum). Eight (13%) of these patients were admitted because of major rectal bleeding, and in seven of the eight the hemorrhage was the initial manifestation of Crohn's disease. The mean age of the entire group was 30 years, with a mean age of 18.6 years in the eight bleeders. Crohn's ileitis should be considered in the differential diagnosis of massive rectal bleeding, especially in younger patients.
4例严重胃肠道出血患者被发现患有克罗恩回肠炎。这促使对克罗恩肠炎连续入院病例进行了为期5年的图表回顾；发现60例患者的疾病局限于回肠远端（很少累及盲肠近端）。其中8例（13%）患者因严重直肠出血入院，8例中有7例出血是克罗恩病的首发表现。整个组的平均年龄为30岁，8例出血患者的平均年龄为18.6岁。在严重直肠出血的鉴别诊断中应考虑克罗恩回肠炎，尤其是在年轻患者中。
