应用螺旋CT技术在诊断肠梗阻方面的准确性分析

目的分析评价应用螺旋CT技术在诊断肠梗阻方面的准确性。方法选取2018年1月至2019年6月本院接诊的28例肠梗阻患者为研究对象,根据就诊顺序分为对照组和观察组,各14例。对照组行腹部X线平片检查,观察组行螺旋CT扫描,比较两种诊断方式的准确率、漏诊率、疾病类型诊断情况以及病因诊断准确率,分析诊断肠梗阻的价值。结果观察组检出肠梗阻13例,检出率为92.86%,漏检1例,漏检率为7.14%;对照组检出肠梗阻8例,检出率为57.14%,漏检6例,漏检率为42.86%。观察组检出率高于对照组,漏检率低于对照组(P<0.05)。对照组检出肠套2例,肠粘连2例,肿瘤1例,肠麻痹3例,观察组检出肠套3例,肠粘连3例,肿瘤1例,肠麻痹6例。观察组肠麻痹检出率均高于对照组(P<0.05),两组肠套、肠粘连及肿瘤检出率比较差异无统计学意义。对照组机械性肠梗阻3例,动力性肠梗阻1例,血液性肠梗阻4例,观察组机械性肠梗阻4例,动力性肠梗阻2例,血液性肠梗阻7例。结论给予肠梗阻患者螺旋CT技术诊断,可提高检出率、降低漏诊率,诊断准确性较高,可明确患者病因以及肠梗阻类型,为临床治疗疾病提供依据,应用价值较高。

Analysis of the accuracy of spiral CT in the diagnosis of intestinal obstruction

Objective To analyze and evaluate the accuracy of spiral CT in the diagnosis of intestinal obstruction.Methods 28 patients with intestinal obstruction admitted from January 2018 to June 2019 were selected as the research subjects,and they were divided into control group and observation group according to the order of treatment,with 14 cases in each group.The control group underwent abdominal X-ray plain film examination,and the observation group underwent spiral CT scan.The accuracy,missed diagnosis rate,diagnosis of disease type and accuracy of cause diagnosis were compared between the two diagnostic methods,and the value of diagnosis of intestinal obstruction was analyzed.Results In the observation group,13 cases of intestinal obstruction were detected,the detection rate was 92.86%,1 case was missed,and the missed detection rate was 7.14%;the control group had 8 cases of intestinal obstruction,the detection rate was 57.14%,and the detection rate was 6 cases.The missed detection rate was 42.86%.The detection rate of the observation group was higher than that of the control group,and the missed detection rate was lower than that of the control group(P<0.05).In the control group,2 cases of intestinal sleeves,2 cases of intestinal adhesions,1 case of tumors,and 3 cases of intestinal paralysis were detected in the control group.In the observation group,3 cases of intestinal sleeves,3 cases of intestinal adhesions,1 case of tumors,and 6 cases of intestinal paralysis were detected.The intestinal paralysis in the observation group were higher than those in the control group(P<0.05),and there was no significant difference in detection rates of intestinal sheath,intestinal adhesions and the detection rate of tumors between the two groups.In the control group,there were 3 cases of mechanical intestinal obstruction,1 case of dynamic intestinal obstruction,4 cases of blood intestinal obstruction.In the observation group,4 cases of mechanical intestinal obstruction,2 cases of dynamic intestinal obstruction,and 7 cases of blood intestinal obstruction.Conclusion Spiral CT diagnosis of intestinal obstruction patients can increase the detection rate,reduce the missed diagnosis rate,and have high diagnostic accuracy.It can clarify the cause of the patient and the type of intestinal obstruction.It can provide strong evidence support for clinical treatment of diseases and application value is high.
