Retrograde Esophageal Dilation in Children without the String

A new technique for retrograde esophageal dilation is presented, which does away with the indwelling string. The method utilizes a Teflon–coated arterial guide wire, which is passed through the gastrostomy and, under fluoroscopy, is directed up the esophagus and out the mouth. The wire is followed by the string and dilators. This method avoids both embarrassment caused by the string and occurrence of the usual complications.
