超声和CT对于肠梗阻诊断差异对比研究

Ultrasound and CT Applies in Diagnosis of Intestinal Obstruction:A Comparison Study

目的:对比超声和CT诊断肠梗阻的差异。方法:选取56例肠梗阻患者,均进行超声诊断与CT诊断,对比两组诊断结果差异。结果:在梗阻诊断、梗阻原因、梗阻部位、肠绞窄四项诊断符合率上,CT诊断率分别为96.43%、92.86%、91.07%、92.11%,超声诊断率分别为91.07%、76.76%、85.71%、89.47%。在梗阻诊断、肠绞窄诊断结果上,CT与超声诊断率差异无统计学意义(P>0.05);在梗阻病因、梗阻部位诊断结果上,CT诊断率显著高于超声诊断(P<0.05)。结论:肠梗阻可首选CT诊断,并辅以超声诊断,从而提高诊断准确率。

Objective： To investigate the differences between ultrasound and CT in diagnosis of intestinal obstruction. Methods： 56 cases of chosen patients with intestinal obstruction were all used both ultrasound and CT diagnosis, then compared their diagnosis results. Results： In the four diagnostic accordance rate included diagnosis, causes, sites and strangulation, the CT＇s rates were 96.43%, 92.86%, 91.07% and 92.11% while ultrasound＇s rates were 91.07%, 76.76%, 85.71% and 89.47%. In the results of diagnosis of obstruction and strangulation, there was no statistical difference between the diagnostic accordance rates of CT and ultrasound（P〈0.05）; while in the results of causes and sites of obstruction, the diagnostic accordance rate of CT was significantly higher than that of ultrasound（P〈0.05）. Conclusion： CT diagnosis can be the first choice for intestinal obstruction,and ultrasound diagnosis should be supplemented to improve the diagnostic accordance rate.
