Objective To investigate the diagnostic value of abdominal X-ray, gastrograf in imaging and 64 multi-slice spiral CT(MSCT)for intestinal obstruction in different locations. Methods The clinical data of 142 patients with intestinal obstruction were reviewed retrospectively. All the patients received abdominal X-ray, gastrograf in imaging and MSCT. The diagnostic accuracy of the three methods was compared. Results The diagnostic accuracy of X-ray, gastrograf in imaging and MSCT in the diagnosis of small bowel obstruction was 62. 5% ,85% and 77. 5% ,the locating accuracy was 0% ,90% and 78. 75% , and the diagnostic accuracy for the cause of obstruction was 0% ,71% and 65% ,respectively. The diagnostic accuracy of the three methods in the diagnosis of large bowel obstruction was 53. 23%' ,73. 17%' and 92% ,the locating accuracy was 38. 17% ,60. 98% and 98% ,and the diagnostic accuracy of MSCT for the cause of obstruction was 91%. Conclusion MSCT has great diagnostic value in identifying the site and cause of intestinal obstruction, especially in large bowel obstruction. Gastrograf in imaging is effective in the diagnosis and treatment of small bowel obstruction,which is a beneficial supplement for MSCT.%目的 探讨腹部平片检查、泛影葡胺口服法造影、64层螺旋CT检查对不同部位肠梗阻的诊断意义.方法 回顾性分析142例肠梗阻患者资料,均行腹部平片、泛影葡胺造影和CT检查,比较其诊断效果.结果 三者对小肠梗阻诊断率为62.5%、85%、77.5%,部位诊断率为0%、90%、78.75%,原因诊断率为0%、71%、65%.三者对大肠梗阻诊断率为53.23%、73.17%、92%,部位诊断率为38.17%、60.98%、98%,CT检查对梗阻原因诊断率为91%.结论 64层螺旋CT检查对肠梗阻部位、原因诊断有极大意义,尤适用于大肠梗阻.泛影葡胺造影在小肠梗阻的诊断和治疗中均有较好的临床应用价值,是CT检查的有益补充.
