Abstract
Objective and Study
Esophageal stenosis is the most common morbidity associated with congenital esophageal atresia (EA). There is no consensus regarding the endoscopic management of strictures in terms of timing and techniques of dilations. The aim of this study is to describe the endoscopic management of esophageal stenosis in children with EA admitted to our tertiary care center.
Methods
A retrospective descriptive single-center study was conducted. Data were collected of all patients diagnosed with EA admitted to the ‘Women's and Children's Hospital’ of Verona, Italy, between 2004 and 2017.
Results
Thirty-seven patients with EA were admitted to our center between 2004 and 2017. Twenty of them were excluded for insufficient data. All patients underwent surgical correction within 2 months of life. An endoscopic control with upper gastrointestinal endoscopy was performed in all of them. Eleven (65%) subjects had tracheoesophageal fistula. All of them had type C EA. Three (18%) had long-gap EA. Eleven patients (65%), 8 with Type C EA and 3 with Type A EA, underwent endoscopic dilation. Semirigid Savary-Giliard bougies were used in most of them. Pneumatic dilation with balloon was performed only in one case. Nine (81%) needed more than one dilation due to anastomotic stricture recurrence. In 3 of the 11 subjects (27%) more than 3 dilations were necessary. Two of them had long-gap EA. The median age of first endoscopic dilation was 3 months (range: 1–12 months). The median age of the last dilation was 6 months (range: 1–18 months). One of the 11 patients who underwent dilations (Type C EA with long gap) underwent surgical retreatment due to fistula recurrence. Six of the 17 subjects (35%) enrolled developed long-term complications.
Conclusion
Our data confirmed that anastomotic stricture is frequent in patients with EA who underwent surgical correction. Endoscopic management of stenosis is a safe and effective procedure that leads to a limited number of complications. Side effects are more likely to occur in patients with long-gap EA. Timing of dilations and endoscopic technique should be defined by international guidelines in order to improve patient's outcome.
