Abstract: Esophageal stenosis is a prevalent condition in children， primarily resulting from anastomotic strictures， corrosive substance injuries， congenital anomalies， gastroesophageal reflux-induced esophagitis， and eosinophilic esophagitis. Although various treatment options are available for pediatric patients with oesophagal stenosis， endoscopic balloon dilatation remains a safe and effective therapeutic choice. This article reviews the preoperative preparation， precautions， complications and treatment of balloon dilatation for esophageal stenosis in children.Furthermore， local adjuvant mitomycin-C therapy can relieve dysphagia and reduce dilation frequency in caustic oesophagal stenosis. Local adjuvant steroid hormone therapy could potentially mitigate refractory oesophagal stenosis. After undergoing endoscopic balloon dilation treatment， the observed increase in weight-for-age Z-scores during follow-up indicates an improvement in nutritional status. Gradual extension of dilation intervals or cessation of further dilation within one year can indicate successful clinical treatment.
