['This study aimed to evaluate the effectiveness of intravenous steroid pulse therapy following balloon dilatation for esophageal stenosis and stricture in children.', 'The study enrolled six children, including three with congenital esophageal stenosis and three with anastomotic strictures after surgery for esophageal atresia, all of whom were treated by balloon dilatation combined with high-dose intravenous methylprednisolone pulse therapy. Methylprednisolone was injected intravenously at a dose of 20\xa0mg/kg/day for 2\xa0days, starting from the day of dilatation, followed by 10\xa0mg/kg/day for 2\xa0days, for a total of 4\xa0days.', 'Esophageal stricture recurred in all three patients with congenital esophageal stenosis despite repeated balloon dilatation without methylprednisolone. However, the symptoms of dysphagia improved and did not recur after systemic steroid pulse therapy following balloon dilatation. Symptoms also resolved in all three patients with anastomotic strictures following balloon dilatation with systemic steroid pulse therapy. All six patients remained asymptomatic after 6-21\xa0months follow-up, with no complications.'] Does steroid pulse therapy prevent restenosis following balloon dilatation for esophageal stricture?
