摘要 目的探讨肿瘤性肠梗阻多层螺旋CT的特征,提高正确诊断率。方法回顾性分析经手术证实的46例肿瘤性肠梗阻患者的CT资料,结果梗阻部位肠壁局限性增厚或软组织肿块,大部分为环形增厚,肠腔变窄,近段肠管扩张、积液,内见液气平面,远段肠管萎陷。46例患者手术证实完全性肠梗阻28例,CT均正确诊断;手术证实不完全性梗阻18例,CT正确诊断率83.33%。CT诊断梗阻部位与手术均相符。结论多层螺旋CT能更清晰和丰富地显示肿瘤性肠梗阻的影像学表现,为其临床诊断提供重要信息。 Objective To discuss the multi-slice spiral CT characteristic of intestinal obstruction caused by neoplasm, to evaluate the right diagnosis rate. Methods The imaging data of 46 cases with intestinal obstruction caused by neoplasm were analyzed retrospectively. Results The feature of multi-slice spiral CT were segmental bowel wall thickening or soft tissue mass in obstructive site, most of that were annular thickening, narrowing of intestinal lumen, dilatation and hydrops of proximal intestine, loss of gas-fluid level in it, and collapse of distal intestine. Surgery confirmed 28 cases with complete intestinal obstruction in 46 cases, and CT diagnosis were exactly; Surgery confirmed 18 cases with imperfect intestinal obstruction, the right diagnosis rate of CT was 83.33%, the obstructive site of CT diagnosis conformed to surgery. Conclusion The multi-slice spiral CT could more clearly and abundantly display the iconography characteristic of intestinal obstruction caused by neoplasm, provide important information for clinical diagnosis.
