title: [Extraluminal foreign body originated from pharynx and esophagus (24 cases report)].
abstract: OBJECTIVE
  To summarize the symptoms, various diagnostic procedures, and therapy of extraluminal foreign body originated from pharynx and esophagus (EFBOPE).
  
  
  METHODS
  Twenty-four patients with EFBOPE were retrospectively reviewed.
  
  
  RESULTS
  Twenty-two cases were removed surgically, 1 case was spontaneous expulsion, 1 case died.
  
  
  CONCLUSIONS
  EFBOPE is seldom seen in the clinical, diagnosis of EFBOPE should be considered whenever haematemesis or haemorrhage, inflammation or abscess in parapharyngeal space outside of pharynx and esophagus are presented after ingesting foreign body. Radiography and computed tomography are main diagnostic tools. Surgical treatment is the only effective method for EFBOPE and must be performed in time.
