摘要
目的：评价ＣＴ对急腹症的诊断价值。材料和方法：对６０例急腹症病人的急诊ＣＴ进行回顾性分析，并对他们的初步临床诊断、ＣＴ诊断及最终诊断作对比研究，结果：初步临床诊断符合最终诊断者仅２１例（３５％），但ＣＴ的定位和定性正确诊断率则分别为１００％和９０％。许多病人ＣＴ检查前临床表现不典型，而ＣＴ表现却十分明显和具特征性，从而ＣＴ诊断常令人感到意外。结论：急腹症病人的临床定位体征及症状有时可能误导，而ＣＴ对这些病人的诊断能起重要作用，因此ＣＴ可作为这些病人诊断的首选方法。由于ＣＴ检查费用相对昂贵，因此根据本分析结果，提出了对急腹症病人合理应用ＣＴ的意见。
Purpose: To evaluate the utility of CT in the diagnosis of acute abdomen.Materials and Methods: Emergent CT studies for 60 cases of acute abdomen were performed.The initial clinical diagnosis, the CT diagnosis,and the final diagnosis were compared and analysed. Results:In 21 (35%)cases the initial clinical diagnosis conformed with the final diagnosis,The localizations of diseases diagnosed by CT were entirely(100%)correct.The specific diagnosis based on CT study was correct in 54(90%)cases.Many patients presented with atypical clinical manifestation,but the CT findings were remarkable and typical.Therefore,the CT diagnoses of these patients made us surprise.Conclusion: Localizing signs and symptoms of acute abdomen is sometimes misleading.CT plays a critical role in evaluation of this group of patients and CT is thus the modality of choice for charaterization of acute abdomen. CT is a relatively expensive examination,therefore, according to our analysis guidelines for its rational use are suggested.
