摘要
目的探讨MSCT诊断小肠扭转的价值。资料与方法对20例小肠扭转术前MSCT预判项目与手术所见对照分析。结果 MSCT预判项目准确率:小肠扭转、肠梗阻程度、腹腔积液均为100%;扭转部位、方向、度数分别为90%、90%、65%;肠血运障碍、腹膜粘连(束带)、病因诊断分别为76%、25%、11%。结论 MSCT能较好显示小肠扭转形态特征,本文初步总结的"3涡缠绕树"征象可能有特异诊断价值,但MSCT对小肠扭转病因诊断尚有限度。
Objective To explore diagnostic value of MSCT liar small bowel volvulus. Materials attd Methods The prefabricating items by MSCT before the opration of 20 cases of small bowel volvulus is analyzed with operation findings. Results The exact rate of prefabricating items by MSCT before the opration of 20 cases as follows： The small bowel volvulus. The ileus extent and The celiac liquid accumulation was all 100%：The local, direction and degree of the Small bowel volvulus respectively was 90（~, 9（）c~ and 65~; The mesenteric ischemia, The peritoneum adherent and etiology diagnosis respectively was 76%. 25% and 1 1%. Conclusion MSCT can preferably reveal configtlration of small bowel volvulus, and Three whirls in the tree with enwinding trunk sign suggesting by the text considerably possess specific diagnostic value for small bowel volvulus,but is finite for the etiologic diagnosis of small bowel wolvulus.
