螺旋CT在86例肠梗阻诊断中的临床应用

Clinical Application of Multisection Helical Computed Tomography in Diagnosis of Intestinal Obstruction in 86 Patients

目的探讨多层CT及重建技术在肠梗阻的诊断及其临床上的应用价值。方法回顾性分析荣昌县人民医院2007年6月-2011年5月期间住院的各类型肠梗阻患者86例,将术前CT检查与术后结果相对照。结果术前CT的病因诊断率为93.02%,实际病因诊断率为82.56%,假阳性率为12.79%,假阴性率为16.28%。结论多层CT检查不仅能提高肠梗阻确诊率,而且可以提高肠梗阻的病因诊断率。

Objective To explore the clinical application value of multisection helical computed tomography and reconstruction technique in diagnosis of intestinal obstruction. Methods The clinical data of 86 patients with various types of intestinal obstruction admitted to the People＇s Hospital of Rongchang County from June 2007 to May 2011 were retrospectively analyzed.The results of preoperative CT examination were compared with postoperative results. Results The etiological diagnosis rate of preoperative CT was 93.02%.The actual etiological diagnosis rate was 82.56%.The false positive rate was 12.79%,and the false negative rate was 16.28%. Conclusions Multi-slice CT scan not only can improve the accuracy rate of diagnosis of intestinal obstruction,but it can also improve the etiological diagnosis rate of intestinal obstruction.
