急性肠梗阻的影像诊断价值分析

Analysis of the Diagnostic Value of Imaging in Acute Intestinal Obstruction

目的研究急性肠梗阻的影像诊断价值。方法选取2018年9月~2020年9月我院诊治的94例急性肠梗阻患者为研究对象,采用随机数字表法分为对照组和观察组,各47例。对照组采用腹部X线平片检查,观察组采用多排螺旋CT检查,比较两组临床诊断敏感度、特异度、阳性和阴性预测值、不同类型(绞窄性、动力性、单纯机械性)肠梗阻检出率、不同病因(肠粘连、肠麻痹、肿瘤、肠套叠)肠梗阻检出率、不同位置(小肠、结肠)肠梗阻检出率。结果观察组急性肠梗阻诊断敏感度、特异度、阳性和阴性预测值均高于对照组,差异有统计学意义(P<0.05);观察组小肠梗阻、绞窄性梗阻、动力性梗阻检出率均高于对照组,差异有统计学意义(P<0.05),单纯性机械梗阻检出率与对照组比较,差异无统计学意义(P>0.05);观察组肠粘连、肠麻痹、肿瘤梗阻病因检出率均高于对照组,差异有统计学意义(P<0.05),肠套叠检出率与对照组比较,差异无统计学意义(P>0.05);观察组小肠、结肠梗阻检出率均高于对照组,差异有统计学意义(P<0.05)。结论CT诊断急性肠梗阻具有良好敏感性和特异性,且可提高梗阻类型和病因检出率,可为临床急性肠梗阻诊断提供更具有指导性的影像学依据,可作为急性肠梗阻患者首选影像学检查方法。

Objective To study the diagnostic value of imaging in acute intestinal obstruction.Methods A total of 94 patients with acute intestinal obstruction who were diagnosed and treated in our hospital from September 2018 to September 2020 were selected as the research objects.They were divided into control group and observation group by random number table method,with 47 cases in each group.The control group was examined by abdominal X-ray plain film,and the observation group was examined by multi-slice spiral CT.Compare the two groups of clinical diagnosis sensitivity,specificity,positive and negative predictive values,the detection rate of different types of intestinal obstruction(stranded,dynamic,pure mechanical),and the detection of different causes(intestinal adhesions,intestinal paralysis,tumor,intussusception)intestinal obstruction The detection rate of intestinal obstruction in different locations(small intestine,colon).Results The sensitivity,specificity,positive and negative predictive values of the diagnosis of acute intestinal obstruction in the observation group were higher than those in the control group,the difference was statistically significant(P<0.05);The detection rates of strangulated obstruction and dynamic obstruction in the observation group were higher than those in the control group,the difference was statistically significant(P<0.05);There was no significant difference in the detection rate of simple mechanical obstruction between the two groups(P>0.05).The detection rates of intestinal adhesions,intestinal paralysis,and tumor obstruction in the observation group were higher than those in the control group,the difference was statistically significant(P<0.05);There was no significant difference in the detection rate of intussusception between the two groups(P>0.05).The detection rate of small bowel and colon obstruction in the observation group was higher than that in the control group,the difference was statistically significant(P<0.05).Conclusion CT diagnosis of acute intestinal obstruction has good sensitivity and specificity,and can improve the detection rate of obstruction types and etiology.It can provide a more instructive imaging basis for the diagnosis of clinical acute intestinal obstruction,and can be used as the preferred imaging method for patients with acute intestinal obstruction.
