title: Giant mid-esophageal diverticula successfully treated by per-oral endoscopic myotomy.
abstract: BACKGROUND
  Surgery is currently the preferred treatment choice for mid-esophageal diverticula, while endoscopic therapy is rapidly establishing itself.
  
  
  METHODS
  We report the first two cases of giant mid-esophageal diverticula presented with dysphagia successfully treated with per-oral endoscopic myotomy (POEM).
  
  
  RESULTS
  There were no complications during the procedure and the patients' conditions improved remarkably within short time of recovery.
  
  
  CONCLUSIONS
  POEM could provide a safe, effective and less invasive treatment of mid-esophageal diverticula if appropriately used. Further studies on long-term efficacy with larger number of cases are necessary.
