摘要
目的对比分析小肠粪便征(SBFS)在正常与异常人群的多层螺旋CT(MSCT)征象,探讨MSCT诊断SBFS的临床价值。方法搜集184名无腹部症状的健康体检者(A组)以及72例小肠梗阻患者(B组)的影像学资料,两组均伴有SBFS。所有受检者均行全腹MSCT平扫,其中同时行增强扫描30例(A组20例,B组10例),将原始图像传到工作站进行多平面重组(MPR),对两组SBFS的MSCT征象进行统计学分析,分类变量采用χ~2检验,数值变量采用t检验,P<0.05为差异有统计学意义。结果A组均无肠梗阻,肠壁不厚,肠系膜脂肪间隙清晰;B组均有肠梗阻,其中轻度梗阻7例,中度梗阻44例,重度梗阻21例,肠壁轻度增厚17例,肠系膜脂肪间隙浑浊41例,CT增强扫描A、B两组SBFS均无强化。SBFS出现的位置、形态、数目及边缘,两组差异均有统计学意义(P<0.05)。A、B两组在性别、发病年龄及腹部手术史差异均有统计学意义。结论MSCT在鉴别正常人群及小肠梗阻患者中的SBFS有重要价值,正确认识SBFS有助于临床诊断和治疗。
Objective To investigate the clinical value of MSCT in the diagnosis of small bowel feces sign by comparing and analyzing the small bowel feces sign(SBFS)in normal and abnormal people.Methods The imaging data of 184 healthy patients without abdominal symptoms(group A)and 72 patients with small bowel obstruction(group B)were continuously collected.Both groups were accompanied by SBFS.All subjects underwent a full-abdominal MSCT scan,including 30 patients(20 in group A and 10 in group B)at the same time.The original images were transferred to the workstation for multi-planar reconstruction(MPR).The MSCT signs were analyzed statistically.The categorical variables were tested byχ~2 and the numerical variables were tested by t-test.P<0.05 was statistically significant.Results There was no intestinal obstruction in group A and the intestinal wall was not thick,and the mesenteric fat space was clear.Group B had intestinal obstruction,including 7 cases of mild obstruction,44 cases of moderate obstruction,21 cases of severe obstruction,and mild thickening of intestinal wall.In 41 cases,the mesenteric fat space was hazy/misty,and the SBFS of CT enhanced scans in group A and B was not enhanced.The location,shape,number and margin of SBFS showed statistically significant differences between the two groups(P<0.05).Differences in gender,age of onset,and history of abdominal surgery were statistically significant between groups A and B.Conclusion MSCT is of great value in identifying SBFS in normal people and patients with small bowel obstruction.Correct understanding of SBFS is helpful for clinical diagnosis and treatment.
