title: Preoperative oesophageal motor activity does not predict postoperative dysphagia.
abstract: OBJECTIVE
  To evaluate the ability of preoperative manometric examinations to predict temporary or permanent dysphagia after antireflux procedures.
  
  
  METHODS
  Retrospective study.
  
  
  METHODS
  Teaching hospital, Sweden.
  
  
  METHODS
  191 patients who had partial fundoplication.
  
  
  METHODS
  Stationary manometry with a perfused catheter system.
  
  
  METHODS
  Correlation between preoperative manometric examinations and the incidence of dysphagia before and after operation.
  
  
  RESULTS
  98 of 191 patients had dysphagia preoperatively (51%), but 52 of the 98 had no stricture or motor disorder to explain it; 25 of 59 patients with motor disorders shown manometrically (42%) did not complain of dysphagia. The number of patients with dysphagia was reduced to 43 postoperatively. 8 who did not complain of dysphagia preoperatively did so postoperatively; 4 of 8 had defective peristalsis and 4 had normal preoperative tracings.
  
  
  CONCLUSIONS
  Manometric examination does not help us to understand the mechanism of preoperative dysphagia, nor does it predict who will develop dysphagia postoperatively.
