A radiologic method for the demonstration of gastroesophageal reflux in children is described, and, while recognizing limitations and pitfalls of any classification, a clinically useful system of grading of reflux is presented. The system is based primarily on the extent of retrograde flow of barium, ranging from reflux into the distal esophagus only (grade 1) to reflux with aspiration into the trachea or lungs (grade 5). The availability of a standardized radiologic technique for the demonstration of gastroesophageal reflux and a system for grading its severity may be useful in understanding the true incidence and significance of this disorder.
本文描述了一种用于显示儿童胃食管反流的放射学方法，并且在认识到任何分类都存在局限性和缺陷的同时，提出了一种临床上有用的反流分级系统。该系统主要基于钡剂逆流的程度，范围从仅反流至食管远端（1级）到反流并误吸至气管或肺部（5级）。一种用于显示胃食管反流的标准化放射学技术以及一种对其严重程度进行分级的系统，可能有助于了解这种疾病的真实发病率和重要性。
