薄层螺旋CT与腹部X线诊断急性肠梗阻影像特征及效能分析

Image characteristics and efficacy analysis of thin slice spiral CT and abdominal X-ray in the diagnosis of acute intestinal obstruction

目的分析急性肠梗阻患者采用薄层螺旋CT与腹部X线诊断的应用效果。方法将2022年7月至2023年7月新干县中医医院收治的70例急性肠梗阻患者纳入研究,患者均接受薄层螺旋CT与腹部X线检查,对2种检查方式的效果进行对比分析,评估指标为2种诊断方式诊断体验效果;2种诊断方式准确率、诊断梗阻部位符合率、诊断效能。结果2种诊断方式进行比较,X线操作复杂度评分较高,薄层螺旋CT舒适度、图像清晰度评分较高;薄层螺旋CT对机械性肠梗阻、麻痹性肠梗阻、血运性肠梗阻、绞窄性肠梗阻等总的诊断准确率高于X线;薄层螺旋CT对结肠、小肠、回盲部等梗阻部位总的符合率高于X线;薄层螺旋CT检查的漏诊率与误诊率分别为0、2.9%,均低于X线检查的17.1%、17.1%(P<0.05)。结论急性肠梗阻患者采用薄层螺旋CT能提高诊断部位符合率和诊断准确率,且薄层螺旋CT舒适度、图像清晰度较好,降低漏诊率和误诊率的发生,但操作较为复杂。

Objective To analyze the application effect of thin-layer spiral CT and abdominal X-ray in the diagnosis of acute intestinal obstruction.Methods From July 2022 to July 2023,70 patients with acute intestinal obstruction treated in Xingan County Traditional Chinese Medicine Hospital were included in the study.All patients underwent thin-layer spiral CT and abdominal X-ray examination.The effects of the two examination methods were compared and analyzed.The evaluation index was the diagnostic experience effect of the two diagnosis methods,the accuracy rate of the two diagnostic methods,the coincidence rate of the diagnosis of obstruction site and the diagnostic efficiency.Results The X-ray operation complexity score was higher,and the thin-layer spiral CT comfort and image clarity score were higher.The overall diagnostic accuracy of thin-layer spiral CT for mechanical intestinal obstruction,paralytic intestinal obstruction,vascular intestinal obstruction,strangulated intestinal obstruction is higher than that of X-ray.The overall coincidence rate of thin-layer spiral CT for obstruction sites such as colon,small intestine and ileocecal region was higher than that of X-ray.The missed diagnosis rate and misdiagnosis rate of thin-layer spiral CT examination were 0 and 2.9%,respectively,which were lower than 17.1%and 17.1%of X-ray examination(P<0.05).Conclusion Application of thin-layer spiral CT in patients with acute intestinal obstruction can improve the diagnostic site coincidence rate and diagnostic accuracy,and the comfort and image clarity of thin-layer spiral CT are better,reducing the incidence of missed diagnosis and misdiagnosis,but the operation is more complex.
