title: [Use of self-expandable prosthesis in esophageal stenosis in children].
abstract: OBJECTIVE
  Caustic or peptic esophageal strictures in children are the main cause of multiple dilations, which involve an important anesthetic risk and esophageal trauma. The placement of an esophageal stent can be an advance in the treatment of these patients. The objective of our work is to analiyze the efficacy of self-expanding stents for the treatment of esophageal strictures in children.
  
  
  METHODS
  Three patients with esophageal strictures, one due to caustic and two to peptic esophageal injuries have been treated with esophageal stents. Metal stent covered with nitinol has been used in the first patient, and biodegradable material stent in the rest.
  
  
  RESULTS
  After a year of serial dilations, we placed two consecutive metal stents in one patient with caustic stricture. After its withdrawal, new dilations have been needed, but with longer asymptomatic period. The other two patients had peptic strictures; biodegradable stents were placed after months of serial dilations, before performing antireflux surgery. None of them needed further dilation.
  
  
  CONCLUSIONS
  Esophageal stent placement has solved the problem without further dilation in peptic esophageal strictures. Asymptomatic period was significantly increased in caustic stricture. The results obtained with self-expanding stents are promising.
