目的 :探讨 CT在急性肠梗阻诊断中的意义。方法 :回顾性分析 45例经手术治疗的急性肠梗阻病人的术前 CT检查资料。结果 :CT对急性肠梗阻病因诊断符合率为 87.1% (2 7/ 31) ,其中对肿瘤引起的肠梗阻、麻痹性肠梗阻有很高准确性。 CT有助于鉴别机械性和麻痹性肠梗阻。 CT对梗阻部位的诊断欠准确。绞窄性肠梗阻的 CT表现有特征性 ,CT的诊断对治疗有指导意义。结论 :CT在急性肠梗阻诊断中有较重要意义 Objective: To investigate the significance of CT in the diagnosis of acute intestinal obstruction. Methods: A retrospective analysis of 45 cases of surgically treated patients with acute intestinal obstruction CT scan data. Results: The coincidence rate of CT in the diagnosis of acute intestinal obstruction was 87.1% (27/31), of which the accuracy of tumor ileus and paralytic ileus was high. CT helps to distinguish between mechanical and paralytic ileus. CT diagnosis of obstructive site is not accurate. Strangulated ileus CT features of CT, the diagnosis of CT is instructive. Conclusion: CT is more important in the diagnosis of acute intestinal obstruction
