传统的结肠钡剂灌肠造影效果不理想,细小的病变如息肉、早期肿瘤等检出率低。为了提高结肠病变X线诊断水平,我院自1977年初开始采用结肠双重造影一次法。通过临床实践,我们认为这种检查方法简便易行,造影效果比较满意,能使较细小的结肠病变得以显示,为早期发现结肠肿瘤创造了良好的条件。现将我们的检查方法简要介绍如下,以供参考。造影方法一、检查前准备要求结肠清洁且粘膜面较干燥,如粘膜 Traditional colonic barium enema imaging results are not satisfactory, small lesions such as polyps, early detection rate is low. In order to improve the diagnosis of colorectal X-ray lesions, our hospital since early 1977 began using colonic double contrast method. Through clinical practice, we believe that this method is simple and easy to check, angiography is more satisfactory, can make smaller colon lesions can be displayed for the early detection of colon tumors to create a good condition. Now our inspection methods are briefly described below for reference. A method of imaging, the preparation of the examination before cleaning the colon and mucosal surface is more dry, such as mucosa
