【摘要】：目的:探討CT鑒別粘連性小腸梗阻所致腸缺血和梗死的價(jià)值。方法 :37例粘連性小腸梗阻患者按照手術(shù)結(jié)果分為小腸缺血組(25例)和梗死組(12例),回顧性比較兩組間CT表現(xiàn)有無(wú)差異,分析有意義的CT表現(xiàn)鑒別腸缺血和梗死的價(jià)值。結(jié)果:腸壁積氣、腸系膜渾濁、腸壁強(qiáng)化減低、腸系膜動(dòng)脈和靜脈強(qiáng)化減低出現(xiàn)的幾率在梗死組顯著高于缺血組(P0.05),預(yù)測(cè)小腸梗死的比數(shù)比分別為3.78、11.91、10.15、16.50、19.55。同時(shí)具備4個(gè)以上征象,預(yù)測(cè)梗死的陽(yáng)性預(yù)測(cè)值達(dá)83.3%(10/12)。結(jié)論:CT有助于鑒別粘連性小腸梗阻所致的腸缺血和梗死,腸系膜靜脈強(qiáng)化減低為最有價(jià)值的CT表現(xiàn)。
[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.
