1、多层螺旋CT在成人肠套叠诊断中的应用价值及病因分析［摘要］目的探讨多层螺旋CT在成人肠套叠诊断中的应用价值，着重研究其对成人肠套叠及其原发病诊断的准确性。方法该研究整群选取并冋顾性分析该院2008年4月一2015年4月收治并经手术证实的52例成人肠套叠患者；手术方法为传统开腹手术,术式为:单纯病变切除术，连同病变在内的部分肠切除术，包扌舌相应的系膜及区域淋巴结在内的肿瘤根治术。术前以多层螺旋CT轴位薄层扫描(平扫或平扫+增强)结合多平面重组技术，分析肠套叠CT征象，查找其原发病灶。结果手术结果显示，有
2、49例属于顺行性肠套叠，3例属于逆行性肠套叠，其中冋肠-结肠型肠套叠26例，结肠-结肠型肠套叠11例，小肠-小肠型肠套叠12例，结肠-直肠型肠套叠3例。术后病理诊断结果显示，良性病变23例，恶性病变28例。术前CT诊断肠套叠47例，准确率为90.38%,正确诊断出原发病变38例，准确率为73.08%。结论多层螺旋CT对于成人肠套叠诊断具有重要价值，能够发现其原发病变，对于其后期诊治起着指导意义。［关键词］多层螺旋CT；成人肠套叠；应用价值；病因［中图分类号］R574.3［文献标识码］A［文章编号］16
