title: Recurrent pyriform sinus fistula successfully treated by endoscopic Glubran 2 sealing: A rare case and literature review.
abstract: OBJECTIVE
  The authors present the case of a 3-year-old girl with a history of complicated surgery for removing a third branchial cleft fistula.
  
  
  METHODS
  An endoscopic approach using N-butyl-2-acrylate and metacrilosisolfolane glue (GLUBRAN 2) to seal the fistula was performed.
  
  
  RESULTS
  The clinical and radiological 6-year follow-up confirmed the absence of the fistulous orifice and the persistence of scar due to previous open-neck surgical procedures.
  
  
  CONCLUSIONS
  endoscopic Glubran 2 sealing has been an effective treatment procedure for branchial fistula.
