胃肠道的 X 线检查技术自1895年伦琴氏发现 X 线后的第二年,就已经有人开始利用它观察试验动物的胃。虽然胃肠道的 X 线检查已有60年的历史,但只是近年来在检查技术或病变解释方面,才有了很大的发展。今天,X 线检查已经成为诊断胃肠道疾患的一种不可缺少的方法。X 线检查不但能确定病理解剖,同时也能观察功能的改变。所以正确的使用它就能准确地做出诊断。这样无论对疾病的冶疗或预后都有很大作用。当然并不是 X 线检查对诊断胃肠道疾患没有任何限制。某些病变由于在发病初期或病变局限于表层,在 X 线检查时可能不被发现。另外有些病变又需要特殊的检查方法或特殊部位才能发现。所以当 X 线检查结果为阳性时,对诊断的价值很大,而当患者具有明显的临床症状(如出血,体重减轻及贫血等)X 线检查为阴性时,就不能除外早期或浅在病变。遇到可疑病例一定要在短期内复查,以免造成错误诊断.下面就胃肠道的 X 线检查技术及各个器官的特殊 Gastrointestinal X-ray Technique Since the second year after Roentgen discovered X-ray in 1895, it has been used to observe the stomach of experimental animals. Although the gastrointestinal X-ray examination has been 60 years of history, but only in recent years in the examination of technology or pathological interpretation, only a great development. Today, X-ray examination has become an indispensable method of diagnosis of gastrointestinal disorders. X-ray examination can not only determine the pathological anatomy, but also to observe the functional changes. So the correct use of it can accurately make a diagnosis. This will have a great effect on the treatment or prognosis of the disease. Of course not X-ray examination for the diagnosis of gastrointestinal disorders without any restrictions. Some lesions due to the onset of disease or lesions confined to the surface, X-ray examination may not be found. In addition, some lesions require special inspection methods or special parts to be found. Therefore, when the X-ray examination results are positive, the value of the diagnosis is great, and when the patient has obvious clinical symptoms (such as bleeding, weight loss and anemia) X-ray examination is negative, you can not except early or shallow lesions . Encountered suspicious cases must be reviewed in the short term, so as to avoid misdiagnosis. The following gastrointestinal X-ray examination and the various organs of the special
