Objective To investigate the endoscopic ultrasonography (EUS) features of benign esophageal stenosis in children. Methods A retrospective analysis was conducted on the medical data of the children who were diagnosed with benign esophageal stenosis from February 2019 to February 2022. The clinical manifestations, EUS findings, and treatment outcome were analyzed to summarize the EUS features of benign esophageal stenosis in children. Results A total of 42 children with benign esophageal stenosis were included. Among these children, 19 (45%) had anastomotic stenosis after surgery for esophageal atresia, with unclear echogenic boundary of the esophageal walls and uneven thicknesses of the surrounding wall on EUS, and had 0-12 sessions of endoscopic treatment (average 2.1 sessions); 5 children (12%) had corrosive esophageal stenosis and 1 child (2%) had physical esophageal stenosis, with unclear stratification of the esophageal walls on EUS, and they had 2-9 sessions of endoscopic treatment (average 5.3 sessions); 1 child (2%) had patchy irregular hypoechoic areas of the esophageal walls on EUS and was diagnosed with tracheobronchial remnants with reference to pathology; 16 children (38%) had unexplained esophageal stenosis and unclear stratification of the esophageal walls on EUS, among whom 6 received endoscopic treatment. During follow-up, 95% (40/42) of the children had significant alleviation of the symptoms such as vomiting and dysphagia. Conclusions For benign esophageal stenosis in children, EUS can help to evaluate the degree of esophageal wall involvement in esophageal stenosis lesions, possible etiologies, and the relationship between the esophagus and the lesion and provide an important basis for selecting treatment modality and avoiding complications, thereby helping to optimize the treatment regimen.
