螺旋CT对107例急性肠梗阻诊断的临床研究

目的：探讨螺旋CT对急性肠梗阻诊断的临床价值.方法：回顾性分析比较107例经手术证实的急性肠梗阻病例的螺旋CT和腹部彩超资料,对二者的诊断结果进行分类讨论.结果：螺旋CT对梗阻定位诊断准确率达59.8％,对梗阻定性诊断准确率达43.0％,对绞窄性肠梗阻的诊断准确率达63.2％,与腹部彩超组比较均具有显著差异（P＜0.05）.结论：螺旋CT对于急性肠梗阻的诊断明显优于腹部彩超,对判断肠梗阻的部位、致病因素,有无绞窄性肠梗阻等效果显著,对临床治疗具有很大的指导作用.

Clinical Research of Spiral CT in Diagnosis of 107 Cases of Acute Intestinal Obstruction

Objective To investigate the clinical value of spiral CT in diagnosis of acute intestinal obstruction. A retrospective analysis of 107 cases with acute intestinal operation was performed for spiral CT data and abdominal doppler ultrasound data, and the diagnoses by the two ones were compared. Results For the intestinal obstruction, spiral CT had an accuracy of 59.8% for localization diagnosis, an accuracy of 43.0% for qualitative diagnosis, and an accuracy of 63.2% for the diagnosis of strangulated intestinal obstruction. There was significant difference between the results by spiral CT and those by abdominal Doppler ultrasound, with P〈0.05. Conclusion Spiral CT behaves better than abdominal Doppler ultrasound for the diagnosis of acute intestinal obstruction, and can determine the site, pathogenic factors and the existence of strangulated intestinal obstruction, and thus can provide instruction for clinical treatment.
