【摘要】：目的:探讨CT鉴别粘连性小肠梗阻所致肠缺血和梗死的价值。方法 :37例粘连性小肠梗阻患者按照手术结果分为小肠缺血组(25例)和梗死组(12例),回顾性比较两组间CT表现有无差异,分析有意义的CT表现鉴别肠缺血和梗死的价值。结果:肠壁积气、肠系膜浑浊、肠壁强化减低、肠系膜动脉和静脉强化减低出现的几率在梗死组显著高于缺血组(P0.05),预测小肠梗死的比数比分别为3.78、11.91、10.15、16.50、19.55。同时具备4个以上征象,预测梗死的阳性预测值达83.3%(10/12)。结论:CT有助于鉴别粘连性小肠梗阻所致的肠缺血和梗死,肠系膜静脉强化减低为最有价值的CT表现。
[Abstract]:Objective: to study the value of CT in differentiating intestinal ischemia and infarction caused by adhesive small bowel obstruction. Methods Thirty-seven patients with adhesive small bowel obstruction were divided into small intestinal ischemia group (25 cases) and infarction group (12 cases) according to the operative results. The CT findings of the two groups were retrospectively compared, and the value of significant CT findings in differentiating intestinal ischemia from infarction was analyzed. Results: the incidence of intestinal wall accumulation, mesenteric opacification, intestinal wall enhancement and mesenteric artery and vein enhancement were significantly higher in the infarction group than in the ischemic group (P0.05), and the ratio of predicting intestinal infarction was 3.78-11.91 ~ 10.15 ~ 16.50 ~ 19.55, respectively. The positive predictive value of infarction was 83.3% (10 / 12). Conclusion 1: Ct is helpful in differentiating intestinal ischemia and infarction caused by adhesive small bowel obstruction, and mesenteric vein enhancement is the most valuable CT manifestation.
