A pediatric case of endoscopic fistula closure using a polyglycolic acid sheet.

Recurrent tracheoesophageal fistula is a common postoperative complication of esophageal atresia [1]. The surgical treatments utilize muscle and pleural flaps [2]. Furthermore, endoscopic fistula closure with fibrin glue, a biomaterial, can be achieved by epithelializing, promoting circulation, and inhibiting leukocyte infiltration [1]. In adults, endoscopic fistula closure using a polyglycolic acid (PGA) sheet is useful for treating postoperative esophageal anastomotic fistulas [3]. However, no such pediatric reports are available.
