机械性肠梗阻的多层螺旋CT诊断

目的:探讨多层螺旋CT(MSCT)在机械性肠梗阻的诊断价值及优势。方法:回顾性分析总结32例经手术病理证实为机械性肠梗阻,并把CT所见与手术病理结果对照。扫描采用MSCT平扫或增强扫描,成像方式为薄层横断面、多方位、多方法重建。结果:诊断肠梗阻的准确率为100%,29例(90.6%)手术结果与MSCT表现相符。包括肠肿瘤14例,肠粘连4例,肠套叠4例,肠扭转2例,肠壁缺血(提示肠绞窄)3例,小肠克隆氏病2例。结论:多层螺旋CT对机械性肠梗阻的程度、部位和梗阻病因的诊断及提示肠缺血有重要价值,可作为肠梗阻的首选检查方法。

Diagnosis of MSCT In Mechanical Intestinal Obstruction

Objective To evaluate the value of multislice computed tomography(MSCT) in the diagnosis of intestinal obstruction. Methods MSCT and surgical findings in 32 cases with mechanical intestinal obstruction were retrospectively analyzed.The thin slice axial image and MPR image were also analysed. Results CT manifestation and surgical findings were consistent in 29(90.6%), including neoplasm(14), adhesions(4), intussusception(4), bowel torsion(2), inflammation(2) and bowel ischemia(3). Conclusion As MSCT can identify the site,level,and cause of obstruction,and show the blood supply of the bowel,it should be suggested as the first choice in diagnosis of bowel obstruction.
