摘要
超声对胃肠道的检查曾经被认为是不准确的,这种观点的理论依据是胃肠道内存在大量气体,而气体的存在是超声检查的主要障碍之一。但1990年以后,人们通过让胃肠道充盈的办法突破了这种限制。胃肠道超声检查已经被认为是很多胃肠道疾病的一种有效诊断工具,胃肠道超声造影检查可以对大肠的大部分,以及胃、小肠的情况在一定程度上作出有效的评估。现主要对胃肠道超声造影检查的优点和缺点进行综述。
Sonography was previously considered inappropriate for the evaluation of gastrointestinal tract.This conventional view is based on the fact that the bowel loop contains gas,one of the major impediments to gastrointestinal visualization.However,since the 1990s,gastrointestinal contrast ultrasonography has been proposed to overcome this limitation by filling the gastrointestinal tract with fluid.Contrast bowel sonography has been accepted as a useful diagnostic tool in various gastrointestinal disorders,including the majority of large intestine,stomach,and small intestine.This article reviews the merits and demerits of contrast gastrointestinal ultrasonography.
