MRI在肠梗阻病因诊断中应用价值分析

Analysis on Application Value of MRI in the Pathogenic Diagnosis of Intestinal Obstruction

为探讨核磁共振(MRI)在肠梗阻病因诊断中的应用价值,选取我院2017年1～12月收治的肠梗阻患者共45例,均进行X线及MRI检查,并与手术病理结果对照,统计X线和MRI检查对肠梗阻定性和定位诊断的符合率,进一步分析肠梗阻的MRI表现及病因诊断情况。结果显示,MRI检查与手术病理结果的定性和定位符合率分别为95.6%、97.8%,显著高于X线检查的73.3%、77.8%(P<0.05);MRI检查肠梗阻病因(肿瘤性肠梗阻、粘连性肠梗阻、肠扭转、粪石梗阻、肠套叠)诊断的符合率分别为94.4%、91.7%、100.0%、100.0%和100.0%,1例小肠肿瘤误诊为炎症,1例粘连性肠梗阻漏诊。结果表明,MRI诊断肠梗阻能够准确显示梗阻部位及病因,可为疾病诊断提供重要信息,值得临床推广应用。

This study was to explore the application value of nuclear magnetic resonance imaging（MRI） in the pathogenic diagnosis of intestinal obstruction（IO）,selected 45 cases of IO admitted in author＇s hospital and received treament from Jan. to Dec. 2017 yr. ;These patients were all inspected by X ray and MRI,the inspected results were compared with pathological exam. results, the match rate of X-ray inspection with and of MRI with the qualitative diagnosis as well with niveau diagnosis,then the MRI finding of IO and pathogenic diagnosis status were further analysed. As results, in the match rate with the qualitative and with niveau diagnosis from pathological examination MRI inspection was significantly higher than X-ray in- spection（95.6% and 97.8% vs 73.3% and 77.8% , P〈0.05,all）,specially,the match rate with pathogenic diagnosis from MRI inspection in tumorous IO, adhesive IO, volvulus, bezoar IO, and intussusception was respectively 94.4%,91.7%,100%,100X and 100%,only 1 case＇s small intestinal tumor was misdiagnosed as inflammation,and 1 case＇s adhesive IO was failed to diagnose. Results show that in diagnosing IO MRI can accurately display obstructive site and cause,thus just provide important information for diagnosis of the disease.It is worthy of clinical popularization and application.
