缺血性肠炎1例诊治分析并文献复习

Analysis of the Diagnosis and Treatment of Ischemic Colitis: A Case Report and Literature Review

摘要: 背景：缺血性肠病亦称缺血性肠炎(ischemic colitis, IC)，是一组因结肠血液供应不足或再灌注损伤所导致的肠道不同程度组织坏死和一系列症状的疾病。IC的人群发病率为4.5/100,000到44/100,000不等，以女性多见。缺血性肠炎患者多以腹痛、腹泻、便血等非特异性消化道症状为主。影像学及结肠镜检查的应用极大地提高了该病的诊断率。病例介绍：本文通过回顾保守治疗缺血性肠炎患者一例，进行文献复习，总结缺血性肠炎的发病机制、临床特点、诊疗策略，以提高对缺血性肠炎的认识。结论：缺血性肠炎是一种少见疾病，极易与其他肠道炎性疾病混淆，诊疗过程中应详细询问现病史、既往史，及时完善全腹CT及结肠镜检查，根据临床症状及辅助检查具体分析，决定治疗方案。

Abstract: Background: Ischemic colitis (IC) is a group of diseases with different degrees of tissue necrosis and a series of symptoms caused by insufficient blood supply or reperfusion injury of colon. Incidence of IC in the general population varies from 4.5 to 44 cases per 100,000 people annually and it affects more women than men. Most patients with IC are abdominal pain, diarrhea, fecal blood and other non-specific digestive tract symptoms. The application of electronic computer X-ray tomography technique (CT) and colonoscopy has greatly improved the diagnosis rate of the disease. Case introduction: This article reviews the literature of a case of IC treated conservatively, summarizes the pathogenesis, clinical characteristics, diagnosis and treatment strategies of ischemic enteritis, so as to improve the understanding of IC. Conclusion: IC is a rare disease, which is easy to be confused with other inflammatory bowel diseases (IBD). In the process of diagnosis and treatment, the current and past history should be inquired in detail, abdominal CT and colonoscopy should be improved in time, and the treatment plan should be decided according to the specific analysis of clinical symptoms and auxiliary examinations.
