摘　　要：目的研究CT小肠成像对肠梗阻部位及病因的诊断价值。方法选取2021年1月-2022年5月在我院诊治的28例疑似肠梗阻患者为研究对象,均行X线、CT小肠成像检查,观察不同检查方法的诊断效能(准确率、敏感度、特异度)、不同部位肠梗阻检出率、不同病因肠梗阻检出率、不同类型肠梗阻检出率、不同病因所致肠梗阻CT影像特点及检查舒适度评分。结果CT小肠成像诊断肠梗阻的准确率、敏感度、特异度均高于X线检查(P<0.05);CT检查对不同部位(空肠、回肠、空回肠、回盲部、结肠部位)梗阻的检出率均大于X线检查(P<0.05);CT检查对不同病因(肠肿瘤、粘连、套叠、肠扭转、腹内外疝)肠梗阻的检出率均大于X线检查(P<0.05);CT检查对单纯性梗阻的检出率与X线比较,差异无统计学意义(P>0.05),CT检查对绞窄性梗阻、动力性梗阻的检出率均高于X线检查(P<0.05);CT检查的舒适度评分高于X线检查(P<0.05);不同病因所致肠梗阻CT检查可表现出不同的影像学特点,并可通过冠状位、矢状位及轴位多角度显示梗阻部位信息。结论CT小肠成像对肠梗阻具有较高的诊断效能,能准确检出病因、梗阻部位,不同病变肠梗阻可表现出一定的CT影像特点,利于临床后期的治疗,且检查舒适度高,可作为诊断肠梗阻的重要手段。Objective To study the diagnostic value of CT enterography in the location and etiology of intestinal obstruction.Methods From January 2021 to May 2022,28 patients with suspected intestinal obstruction diagnosed and treated in our hospital were selected as the research objects.All patients underwent X-ray and CT enterography.The diagnostic efficacy(accuracy,sensitivity,specificity)of different examination methods,the detection rate of intestinal obstruction in different parts,the detection rate of intestinal obstruction in different causes,the detection rate of intestinal obstruction in different types,the CT imaging characteristics of intestinal obstruction caused by different causes and the comfort score of examination were observed.Results The accuracy,sensitivity and specificity of CT enterography in the diagnosis of intestinal obstruction were higher than those of X-ray examination(P<0.05).The detection rate of obstruction in different parts(jejunum,ileum,jejunum,ileum,ileocecal and colon)by CT was higher than that by X-ray(P<0.05).The detection rate of CT examination for intestinal obstruction of different causes(intestinal tumor,adhesion,intussusception,intestinal torsion,internal and external hernia)was higher than that of X-ray examination(P<0.05).There was no significant difference in the detection rate of simple obstruction between CT and X-ray(P>0.05).The detection rate of strangulated obstruction and dynamic obstruction by CT was higher than that by X-ray(P<0.05).The comfort score of CT examination was higher than that of X-ray examination(P<0.05).CT examination of intestinal obstruction caused by different causes can show different imaging features,and can show the location of obstruction through coronal,sagittal and axial multi-angle information.Conclusion CT enterography has a high diagnostic efficiency for intestinal obstruction,which can accurately detect the etiology and obstruction site.Different lesions of intestinal obstruction can show certain CT imaging characteristics,which is conducive t
