利用不等量的钡剂,而显示不同密度的对比灌肠方法的优点是: 一、可免除结肠重叠,避免透视或摄片的困难。如乙状结肠位于右侧,或横结肠及回肠位置过纸等情况下,可见肠内不等量的钡剂而显示不同密度的对比。二、可节省钡剂60％左右。近年来我们利用此灌肠方法,收到很好的效果,现介绍如下; The use of different amounts of barium, and shows different density contrast enema The advantages of the method are: First, to avoid colon overlap, to avoid the difficulty of fluoroscopy or radiography. Such as the sigmoid colon is located on the right, or transverse position of the ileum and paper over the case, we can see the different amount of barium in the intestine to show the contrast of different densities. Second, can save about 60% of barium. In recent years, we use this method of enema, received very good results, are presented below;
