[Endoscopic closure of a recurrent tracheoesophageal fistula]

We report a successful endoscopic obliteration of a large recurrent tracheo-esophageal fistula (diameter 0.6 cm, length 2 cm) in a 12-year old girl, using a combination of N-butyl-2-cyanoacrylate followed by polidocanol injected through a polyethylene catheter. The severe pulmonary infection, that rendered surgery potentially life-threatening, resolved after endoscopic closure. The girl remained asymptomatic for 14 months after the first obliteration. Chronic coughing was the symptom of relapse. A follow-up endoscopy revealed that most of the N-butyl-2-cyanoacrylate had disappeared from the fistula, whose endoscopic appearance was unchanged. A second obliteration with the same products was performed. The girl has again been asymptomatic for 10 months. The endoscopic obliteration is a worth-while technique, to be considered as an alternative to surgery in patients presenting with a complicated recurrent tracheo-oesophageal fistula.
