title: Manometric assessment of esophageal motility in patients with primary Sjögren's syndrome.
abstract: OBJECTIVE
  The aim of this study was to assess the esophageal motility by manometry in patients with primary Sjögren's syndrome.
  
  
  METHODS
  Esophageal manometry was carried out in 40 patients with primary Sjögren's syndrome (SS), 15 with rheumatoid arthritis (RA), 15 with RA and secondary SS, and 21 healthy volunteers.
  
  
  RESULTS
  We found that the mean lower esophageal sphincter (LES) pressures measured by station pull-through and rapid pull-through techniques were significantly higher in primary SS patients than with healthy controls and RA patients with or without SS (P<0.05). Our study did not show any major differences when comparing the three patient groups (P>0.05). However, peristaltic contraction velocity was lower and peristaltic contraction duration significantly higher at the middle and lower thirds of the esophagus in primary SS patients than in healthy controls (P<0.05).
  
  
  CONCLUSIONS
  The results of our study support the view that various esophageal motility disorders can be found in patients with primary SS which could be related to an increase in LES pressure. We also found no correlation of the esophageal abnormalities with other factors studied, suggesting that the cause of dysphagia is multifactorial in nature.
