Endosonographic Evaluation in Two Children With

The authors report the successful use of endoscopic ultra-sonography (EUS) for finding the etiology and subsequent treatment strategy for esophageal stenosis in 2 children. In case 1, EUS showed anterior wall thickening and multiple low echoic regions in the mp layer. These regions were believed to be cartilage. Esophageal resection therefore was performed. In case 2, EUS showed disruption of the sm and mp layers at the stenosis, leading us to speculate that the stenosis was caused by gastroesophageal reflux. After bal-loon dilatation, he underwent antireflux surgery of Nissen’s fundoplication. EUS was useful for determining the etiology of esophageal stenosis and, thus, the appropriate treatment strategy
