多层螺旋CT检查诊断肠梗阻的应用及准确度评价

Application and Accuracy Evaluation of Multi-slice Spiral CT in the Diagnosis of Intestinal Obstruction

目的 研究在肠梗阻的临床诊断中应用多层螺旋CT检查的价值。方法 选取2022年1月—2023年12月新泰市人民医院收治的917例疑似肠梗阻患者为研究对象,所有受试者入院后均接受多层螺旋CT扫描。以临床表现、体格检查和影像学检查等综合诊断为金标准,分析多层螺旋CT的诊断符合率与诊断效能。结果 在疑似肠梗阻患者中,综合诊断确诊915例肠梗阻患者,多层螺旋CT诊断的准确度、灵敏度、特异度依次为99.89%(916/917)、100.00%(915/915)、50.00%(1/2),kappa值为0.666。CT对不同类型肠梗阻的诊断符合率为99.89%(914/915)。结论 多层螺旋CT检查对诊断肠梗阻具有较高的准确度、灵敏度。

Objective To study the value of using multi-slice spiral CT in the clinical diagnosis of intestinal obstruction.Methods A total of 917 patients with suspected intestinal obstruction admitted to Xintai People 's Hospital from January 2022 to December 2023 were selected as the study subjects.All subjects underwent multi-slice spiral CT scan after admission.The diagnostic coincidence rate and diagnostic efficiency of multi-slice spiral CT were analyzed with the comprehensive diagnosis of clinical manifestations,physical examination and imaging examination as the gold standard.Results Among the patients with suspected intestinal obstruction,915 patients with intestinal obstruction were diagnosed by comprehensive diagnosis.The accuracy,sensitivity and specificity of multi-slice spiral CT diagnosis were 99.89%(916/917),100.00%(915/915) and 50.00%(1/2),respectively,and the kappa value was 0.666.The diagnostic coincidence rate of multi-slice spiral CT for different types of intestinal obstruction was 99.89%(914/915).Conclusion The application of multislice spiral CT examination has high accuracy and sensitivity in diagnosing intestinal obstruction.
