摘要
探讨急诊螺旋CT在肠梗阻诊断中的意义。回顾性分析手术证实为肠梗阻，CT和立位腹平片资料齐全的。41例中CT诊断均有不同程度的肠梗阻，手术证实CT诊断部位明确为41例，病因明确为39例，包括结肠肿瘤9例，肠粘连20例，肠扭转3例，粪石5例。肠系膜血管缺血1例，克罗恩（降结肠）1例，嵌顿疝1例，胰腺囊肿1例。与手术结果对照，符合率分别为100％和91％。结论多排螺旋CT对肠梗阻的病因、部位的诊断具有重要意义，有助于及时指导有效的治疗，判断预后，可作为肠梗阻的首选检查方法。
Objective To analyse the value of multidetecter computed tomography （MDCT） in the diagnosis of intestinal obstruction. Methods MDCT and surgical findings in 41 cases with acute bowel obstruction-were retrospectively analyzed.The thin slice axial image and MPR image were also analysed. Results CT manifestation and surgical findings were consistent in 41, including neoplasm （9）, adhesions （20）, bowel torsion （3）, fecalith （5） and bowel ischemia （1）, crohn disease （1）, incarcerated hernia （1）, pancreatic cyst（l）. Conclusion As MDCT can identify the site, level, and cause of obstruction, and show the blood supply of the bowel, it should be suggested as the first choice in diagnosis of bowel obstruction.
