A Single Center Experience of Self-bougienage on Stricture Recurrence After Surgery for Corrosive Esophageal Strictures in Children

Purpose: This study was undertaken to evaluate the long-term treatment of esophageal strictures in children with corrosive esophagitis and to determine the effect of self-bougienage on recurrent strictures.

Materials And Methods: We reviewed the medical records of nine children that were treated for corrosive esophageal strictures from May 2000 to May 2008. Six males and three females were included and their average age was 30 months. Six patients had ingested acids, two patents had ingested alkali, and one ingested an unknown agent.

Results: The interval between caustic ingestion and esophageal stricture ranged from one to eight weeks. The average length of the esophageal strictures was 3.8 cm (range, 1 to 9.2 cm). Four patients had a long segment stricture (longer than 5 cm) and one patient had multiple strictures. The most common site of involvement was the upper third followed by the mid third of the esophagus. Eight patients received repeated dilatation using a balloon catheter or bougie dilator. Among the eight patients, two patients had complete resolution of symptoms and six patients required surgery. Among five patients that developed restenosis of the esophageal anastomosis site, three patients had improved symptoms after self-bougienage and two patients had improved symptoms with repeated balloon dilatation or endoscopic bougienage. There were no complications in these patients.

Conclusion: Although a small number of patients were studied, self-bougienage was safe, less invasive, and effective for the management of esophageal restenosis in patients who required frequent dilation after surgery.
