title: [Presurgical evaluation and surgical treatment of medically refractory epilepsy: a report of 162 cases].
abstract: OBJECTIVE
  To study presurgical evaluation and surgical treatment of medically refractory epilepsy.
  
  
  METHODS
  One hundred and sixty-two cases of refractory epilepsy were analysed by their clinical manifestation, neuroradiology and neuroelectrophysiology. Different operative techniques were performed to all the 162 cases according to those analyses.
  
  
  RESULTS
  Total effective rate of the surgical treatment was 87.7% and most patients have better life than preoperation.
  
  
  CONCLUSIONS
  Surgical treatment with accurate preoperative location of the epileptogenic zone and suitable operative techniques is an effective method in the treatment of refractory epilepsy.
