目的研究腹部X线平片与64排螺旋CT对胃后壁穿孔患者游离气体检出率。方法笔者于2012年2月-2014年2月,共收集了46例被诊断为胃后壁穿孔的病患。所有患者在手术前均采用腹部X线平片以及64排螺旋CT进行扫描检查,对比观察两种方法对游离气体的检出率以及扫描准确率。结果 64排螺旋CT对游离气体的检测率显著高于X线的检出率,且正确率显著高于X线;同时64排螺旋CT还可以准确检测出穿孔部位;以上差异均有统计学意义(均P<0.05)。结论 64排螺旋CT对胃后壁患者游离气体检出率显著高于腹部X线平片,且准确率高,值得临床推广使用。
Objective To study the detection rate of free gas in patients with posterior gastric wall perforation through X-ray and 64-slice spiral CT. Methods From February 2012 to February 2014, 46 patients who were diagnosed as perforation of the posterior wall of the stomach were collected. All patients underwent preoperative abdominal X-ray and 64-slice spiral CT scan comparison of the two methods to detect the rate of free gas and scan accuracy. Results The detection rate of free gas by 64-slice spiral CT was significantly higher than that of X-ray, and the correct rate was significantly higher than that of X-ray. At the same time, the 64-slice spiral CT also could accurately detect the perforation site. The above differences were statistically significant (All P <0.05). Conclusion The detection rate of free gas in patients with posterior gastric wall by 64-slice spiral CT is significantly higher than that of abdominal plain radiography, and the accuracy is high, which is worthy of clinical promotion.
