title: Case report: successful resection of a leiomyoma causing pseudoachalasia at the esophagogastric junction by tunnel endoscopy.
abstract: BACKGROUND
  Pseudoachalasia is a rare disorder whose presentation strongly resembles idiopathic achalasia.
  
  
  METHODS
  Here, we present a case of a 42-year-old female patient with esophageal leiomyoma who was initially diagnosed with achalasia. On endoscopical investigation, however, it became apparent that she had pseudoachalasia as consequence of a leiomyoma at the esophagogastric junction (EGJ). The condition was successfully treated through submucosal tunneling endoscopic resection.
  
  
  CONCLUSIONS
  This case suggests that submucosal tunneling endoscopic resection is a therapeutic u option for the treatment of pseudoachalasia caused by leiomyoma of EGJ.
