Esophageal dilatation by endoscopists is a commonly performed procedure. The introduction of tapered polyvinyl dilators by Savary has made the procedure even more popular. In the United States, esophageal dilatation with guide wires has been traditionally performed with fluoroscopy. By using a marked guide wire and by adhering to specific safety guidelines, the passage of the guide wire can be precise, even without fluoroscopy, and radiographic definition is not always required. This study describes the new guide wire and the technique.
内镜医师进行食管扩张是一种常见的操作。萨瓦里引入的锥形聚乙烯扩张器使该操作更加普及。在美国，传统上使用荧光透视进行带导丝的食管扩张。通过使用带标记的导丝并遵循特定的安全指南，即使不使用荧光透视，导丝的插入也可以很精确，而且并不总是需要影像学定位。本研究描述了这种新型导丝及其技术。
