title: [The treatment to esophagus stricture with Ni-Ti shape memory alloy stand(with the report of 19 clinical cases)].
abstract: OBJECTIVE
  To discuss the use of Ni-Ti shape memory alloy stand in treating the stricture of esophagus.
  
  
  METHODS
  After finding the stricture part of esophagus under X-ray, the metal guide string was put through the esophagoscope. Dilatation of esophagus was performed firstly. Then the inserting instrument, which has the Ni-Ti shape memory alloy stand inside, was put through the stricture part along the metal guide string and the stand which can return to its original shape automatically was released. Barium meal examination of esophagus was performed after the operation to determine the site of the stand and to realize the smooth degree of esophagus.
  
  
  RESULTS
  All 19 patients got a successful operation at one time. They swallowed freely after the operation. The effective rate was 100%.
  
  
  CONCLUSIONS
  Ni-Ti shape memory alloy stand can dilate the stricture of esophagus quickly, improve swallowing function obviously. The operation can be easily performed. The therapeutic effectiveness is reliable, and there is no serious complication. This can be used as a routine method in treating the stricture of esophagus.
