title: Nonobstructive dysphagia and recovery of motor disorder after antireflux surgery.
abstract: BACKGROUND
  Changes in motor disorder after Nissen 360 degrees surgery were studied based on clinical signs of preoperative nonobstructive dysphagia.
  
  
  METHODS
  Forty-seven patients undergoing Nissen 360 degrees fundoplication for gastroesophageal reflux were studied with pH recording and esophageal manometry before and 1 year after fundoplication. Amplitude of contraction of the distal third of the esophagus (ACDTE) and the presence of primary propulsive waves were studied.
  
  
  RESULTS
  Fourteen patients had clinical signs of preoperative dysphagia. Of these, 50% had an ACDTE lower than 30 mm Hg, and 71.4% nonpropulsive waves (P <0.05). Forty-three percent and 30%, respectively, of patients with dysphagia recovered ACDTE and the presence of primary propulsive waves 1 year after the procedure, as compared with 66.6% (P <0.05) and 81.8% (P <0.01%) of patients without dysphagia.
  
  
  CONCLUSIONS
  A correlation was found between preoperative dysphagia and esophageal motility disorders (P <0.05). One year after fundoplication, recovery was significantly higher in patients without preoperative dysphagia.
