本文通过临床X线测试,介绍一X线检查逆流的程序。它能对返流的方式、程度、食管对返流物的廓清能力以及对食管造成的损害作出客观估计。根据逆流的X线表现,初步把返流的方式分为顿挫、倾倒、虹吸及混合四型。把食管的廓清方式分为主动,被动,延迟,交替四型。并探讨返流的发生机制,以冀找到合适的防止和治疗返流的方法。 This article through the clinical X-ray test, introduced a X-ray check countercurrent program. It provides an objective estimate of the mode and extent of regurgitation, the ability of the esophagus to regress reflux and the damage it causes to the esophagus. According to the countercurrent X-ray performance, the initial way to reflux is divided into frustration, dumping, siphon and mixed four. Esophageal clearance method is divided into active, passive, delayed, alternating four. And to explore the mechanism of regurgitation in order to find a suitable method to prevent and treat reflux.
