摘要
目的探讨多层螺旋CT(MSCT)对急性肠梗阻的诊断价值。方法回顾分析有随访结果的临床或X线、CT检查诊断为急性肠梗阻的50例病例CT及X线平片资料。结果MSCT诊断肠梗阻存在的正确率96%(48/50),敏感性95.34%(41/43),特异性92%(46/50);X线立卧位平片诊断有无肠梗阻存在的正确率66%(33/50),敏感性76.74%(33/43),特异性68%(34/50)。经手术或随访证实的17例CT检查病因诊断正确率82.35%(14/17),定位诊断正确88.23%(15/17)。结论MSCT能准确判断有无肠梗阻存在,显示梗阻部位及判断梗阻病因。
Objective To evaluate the role of MSCT in the diagnosis of acute ileus. Methods CT and abdominal X-ray plain film i-mdings in 50 cases with acute ileus, proved by MSCT or clinical follow-up, were retrospectively analyzed. Results The existence of ileus was diagnosed in 96%（48 of 50 cases） on MSCT scans, the sensitivity was 95. 34%（41 of 43 cases）, the specificity was 92%（46 of 50 cases）. The accurate rate of X-Ray plain film in the diagnosis of ileus in this study was 66%（33 of 50 cases）, the sensitivity was 76.74%（33 of 43 cases）, the specificity was 68%（34 of 50 cases）. The accuracy of etiological diagnosis of ileus made by MSCT in 17 cases proved by operation or clinical follow-up was 82.35%（14 of 17 cases）, and the accuracy of location was 88.23%（15 of 17 cases）. Conclusion MSCT could accurately find out whether ileus exists, and identify the site and cause.
