Postsurgical stricture is the most common cause of esophageal stenosis in children after congenital esophageal atresia repair, followed by congenital esophageal stenosis and chemical corrosion burns. Endoscopic or radiologic balloon dilation is the standard method for treatment of esophageal stenosis, but in some complicated cases with severe hyperplasia and severe restenosis and even occlusion, the effect of endoscopic treatment is limited. In 1993, Bulynin et al reported, for the first time, the successful use of magnetic recanalization technology to treat refractory esophageal stenosis in children and pioneered the history of magnetic surgery to treat pediatric esophageal diseases. This technologymakes full use of magnetic devices and forces which can effectively remove the scar tissue in the anastomotic region without damaging the muscle layer of the digestive tract wall and obtain the ideal therapeutic effect after surgery. In the past decade, magnetic recanalization technology has been further developed for the treatment of esophageal stenosis in children, which is superior to endoscopic dilatation and other methods, providing a new tool for the treatment of recalcitrant esophageal stenosis in children.
