【摘要】 目的 探讨以下消化道大出血为首发症状的克罗恩病的诊断和治疗。方法 回顾性分析1例该病患者的临床资料，并对相关文献进行复习和总结。结果 采取输血和支持疗法，静脉输注生长抑素，稳定生命体征后，行电子结肠镜及病理组织学检查，明确诊断为克罗恩病。用皮质激素和柳氮磺胺吡啶治疗后痊愈出院。结论 当下消化道大出血作为克罗恩病的首发症状，而肠道症状很不典型或缺乏时，结肠镜检查有重要价值。生长抑素有利于止血，皮质激素和柳氮磺胺吡啶仍为治疗克罗恩病的主要药物。

Abstract: Objective To investigate the strategy in the diagnosis and treatment of Crohn disease that represents lower gastrointestinal tract massive hemorrhage as the first symptom. Methods A case of Crohn disease successfully diagnosed and treated was reported here, with the pertinent literature reviewed. Results Blood transfusion and supportive therapy with somatostatin iv gt were administered. When the vital signs were stabilized, electronic colonoscopy and histopathologic examination were performed to establish the final diagnosis of Crohn disease. Following a course of standard adrenocortical hormone and SASP therapy, the patient fully recovered from illness. Conclusion Coloscopy is valuable for diagnosing the Crohn disease that represents massive hemorrhage of lower gastrointestinal tract as the first symptom, especially in case the intestinal symptoms are lacking or atypical. Somatostatin is effective for treating alimentary tract hemorrhage, but adrenocortical hormone and SASP are still the principal medicines for Cohn disease.

克罗恩病(Crohn disease， CD)是一种原因不明的胃肠道慢性炎性肉芽肿性疾病，可侵犯消化道任一部位。其临床缺乏特异性表现，除消化道症状外，还常累及肠外多个系统，症状多样化[1]。但以下消化道大出血为首发症状的克罗恩病罕见。我科收治1例，现报道如下，并对相关文献进行复习和总结，探讨该病的诊断和治疗。
