title: [Etiology and treatment of delayed epistaxis after endoscopic surgery].
abstract: OBJECTIVE
  To evaluate the etiology and management of delayed epistaxis after endoscopic surgery.
  
  
  METHODS
  To retrospectively analyze the clinical data of 11 cases for epistaxis after nasal endoscopic surgery. To compare their precipitating factors, their surgical approach, time and site of bleeding and management in order to find the intrinsic rules.
  
  
  RESULTS
  The precipitating factors, bleeding sites and treatments varied among patients.
  
  
  CONCLUSIONS
  Delayed epistaxis after endoscopic surgery can not be neglected. There may be some precipitating factors. The surgical approach may be related to the bleeding site. It is better to treat the epistaxis using the endoscope to explore the bleeding site and to give corresponding intervention.
