多层螺旋CT对急性机械性肠梗阻的诊断价值

The diagnostic value of multi-slice spiral CT in acute mechanical intestinal obstruction

目的探讨16层螺旋CT对急性机械性肠梗阻的诊断价值。方法回顾性分析我院2011年1月－2013年10月收治142例经手术证实为机械性肠梗阻的病例资料,分别计算腹部立卧位X线片（X线CR）和16层螺旋CT对肠梗阻定性、定位、程度及病因的诊断符合率（准确率）,并行率的统计学比较。结果腹部X线CR对肠梗阻定性诊断、梗阻原因诊断、梗阻部位诊断、梗阻程度诊断符合率均显著小于16层螺旋CT（P〈0.05）;患者舒适度、图像清晰度均显著小于16层螺旋CT（P〈0.05）,而操作难度却显著高于16层螺旋CT（P〈0.01）。结论 16层螺旋CT对肠梗阻的定性、定位、程度、病因等方面有较高的诊断率,值得在临床上推广使用。

Objective To investigate the diagnostic value of 16-slice spiral CT（MSCT）in acute mechanical intestinal obstruction. Methods A retrospective analysis was conducted on 142 cases of mechanical intestinal obstruction confirmed by surgery cared by our hospital from January 2011 to October 2013,we separately calculated out the accordance rates（accuracy）of intestinal obstruction qualitation,location,degree,and causes presented by abdominal X-ray plain films（when standing up and lying back on table X-ray CR）and MSCT,at the same time a statistical comparison of the accuracy rate was performed. Results The accurate rates of qualitative,causes,obstructive position and the degree diagnosis were all lower in abdominal X-ray CR than in16-slice spiral CT（P〈0.05）;and the patients＇ comfort,images clarity were all significantly lower than 16-slice spiral CT（P〈0.05）,and more easily operation in 16-slice spiral CT（P〈0.01）. Conclusion The 16- slice MSCT has higher diagnostic rates for qualitation,location,degree and etiology,et al and is worthy of spreading clinically.
