多层螺旋CT在急性肠梗阻诊断中的应用

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。

The application of MSCT to the diagnosis of acute ileus

Objective To evaluate the role of MSCT in the diagnosis of acute ileus. Methods CT and abdominal X-ray plain film findings 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.
