目的探讨电子计算机体层摄影(CT)在急性肠梗阻病因诊断中的意义。方法对近年来26例急性肠梗阻病人术前腹部 CT 检查资料进行回顾性分析。结果 CT 对急性肠梗阻的病因诊断符合率为84.6%(22/26)。对老年病人优势尤为明显,其中对肿瘤引起的肠梗阻、肠套叠等可提出明确诊断;对肠扭转引起的急性肠梗阻诊断正确率低;对麻痹性肠梗阻可得出正确诊断。对肠系膜静脉血栓形成的 CT检查,无创且诊断正确率高,明显优于其他有创检查方法。结论 CT 对急性肠梗阻的病因诊断有重要意义。
Objective To investigate the significance of computed tomography (CT) in the etiological diagnosis of acute intestinal obstruction. Methods The data of 26 cases of acute intestinal obstruction in recent years were analyzed retrospectively. Results The coincidence rate of CT diagnosis of acute intestinal obstruction was 84.6% (22/26). The advantages of elderly patients is particularly evident, of which the tumor caused by intestinal obstruction, intussusception, etc. can make a clear diagnosis of intestinal obstruction caused by acute intestinal obstruction diagnostic accuracy is low; paralytic ileus can be diagnosed correctly. The detection of mesenteric venous thrombosis CT, noninvasive and high diagnostic accuracy, significantly better than other invasive detection methods. Conclusion CT is of great significance in the diagnosis of acute intestinal obstruction.
