【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回顾性分析该院2008年4月—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,包括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49例属于顺行性肠套叠,3例属于逆行性肠套叠,其中回肠-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。
[Abstract]:Objective to evaluate the value of multilayer spiral CT in the diagnosis of adult intussusception, and to study its accuracy in diagnosis of adult intussusception and its primary disease. Methods 52 adult patients with intussusception were selected and analyzed retrospectively from April 2008 to April 2015. The operative method is traditional laparotomy, simple lesion resection, partial enterectomy, including the corresponding mesentery and regional lymph nodes. Multislice spiral CT axial thin slice scanning (plain scan or plain contrast enhancement) combined with multiplanar recombination technique was used to analyze the CT signs of intussusception and to find out the primary lesion of intussusception. Results there were 49 cases of anterograde intussusception and 3 cases of retrograde intussusception, including 26 cases of ileo-colonic intussusception, 11 cases of colon-colon intussusception, 12 cases of enteric-intestinal intussusception. Colon-rectum intussusception 3 cases. Postoperative pathological diagnosis showed 23 cases of benign lesions and 28 cases of malignant lesions. 47 cases of intussusception were diagnosed by CT before operation, the accuracy rate was 90.38, 38 cases were diagnosed correctly, the accuracy rate was 73.08. Conclusion Multi-slice spiral CT is of great value in the diagnosis of adult intussusception, can find its primary changes, and play a guiding role in the diagnosis and treatment of adult intussusception.
