磁共振成像对小肠及结肠肠梗阻的诊断价值初探

摘要

Objective To study the significance of MRI (magnetic resonance imaging) in determining the plane of intestinal obstruction and analyzing obstruction factors.Methods 89 cases of pathology obstruction patients who are confirmed through surgical pathology without preoperative bowel preparation from November 2007 to May 2012 are collected.Results Among 89 cases of patients,there are 45 cases of small bowel obstruction accounting for 50.6％ and 44 cases of colonic obstruction accounting for 49.4％.The MRI positioning diagnostic accuracy rate are 96.6％(86/89).There are statistical differences between small bowel obstruction group and colorectal obstruction group in the accuracy of MRI etiology diagnosis.Conclusion MRI without preoperative bowel preparation leads to a better display of the obstruction and plays an important role in confirmation of pathogenesis.%目的 初步分析磁共振成像(MRI)在确定大肠和小肠肠梗阻平面和分析梗阻因素中的价值.方法 收集2007年1 1月～2012年5月间我院收治的经手术病理证实的肠梗阻患者89例,进行无肠道准备的MRI.结果 89例均经手术证实,其中小肠梗阻45例(50.6％)、结肠梗阻44例(49.4％).本组89例肠梗阻患者术前MRI定位符合率96.6％(86/89),无肠道准备的MRI对小肠梗阻组及结肠梗阻组的病因诊断准确率差异有统计学意义.结论 无肠道准备的MRI可以较为明确地显示肠梗阻的部位,对确定病因也有很大帮助.
