肠梗阻CT影像分析与临床应用

目的通过对肠梗阻的CT影像分析,了解其CT影像学特征,评价CT在肠梗阻诊断中的应用价值。方法对2008年1月~2013年6月四川省蓬溪县人民医院收治的186例经CT诊断的肠梗阻患者的病历资料进行回顾性分析。结果 186例患者CT检查均有肠管扩张,肠腔出现气液平影像,肠壁变薄,梗阻近端肠管积气扩张直径大于5cm,远端肠管萎陷小于5cm,远近端肠管直径有显著差异。结论 CT检查中,肠梗阻的影像学特征较为典型,能清楚显示梗阻是否存在、梗阻部位、梗阻原因,可作为首选检查方法。

Objective To investigate the CT features of intestinal obstruction and to to evaluate the application value of CT in diagnosis of intestinal obstruction.Methods Clinical datas of 186 cases diagnosed by CT from January 2008 to June 2013 were retrospectively analyzed. Results The CT image of 186 cases with intestinal obstruction is bowel dilatation, gas-liquid plane in intestinal cavity, Obstruction of the proximal bowel product greater than 5 cm in diameter, gas expansion of the distal bowel atelectatic less than 5 cm, far and near end long intestinal tube diameter has a signiifcant difference.Conclusion The imaging features is typical that intestinal obstruction is checked by CT which can show whether there is obstruction, the obstruction site and reasons, and can be used as the preferred method of inspection.
