title: The pattern of esophageal manometry in progressive systemic sclerosis.
abstract: OBJECTIVE
  The purpose of this paper is to study the esophageal motility pattern and the frequency of acid reflux in patients diagnosed to have progressive systemic sclerosis and compare the results to that of normal controls.
  
  
  METHODS
  All consecutive patients diagnosed to have progressive systemic sclerosis between 1417-1419 (Hijra year) at King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia were included (Group I). History of heartburn, dysphagia and regurgitation was reviewed. Drugs that might suppress acid or alter motility were discontinued 2 weeks before inclusion. The results were compared to that of 21 symptomatic controls of similar age and sexes that were seen at the same period (Group II). Esophageal manometry and upper gastrointestinal endoscopy were performed in all patients. Ambulatory 24 hour-pH monitoring was carried out in 6 patients of group 1 and 20 patients of group II.
  
  
  RESULTS
  Thirteen progressive systemic sclerosis patients (12 females) mean age was 38.7 years and 21 (19 females) mean age was 34.8 years were included. The symptom scores, lower esophageal sphincter pressure, esophageal contractions amplitude were significantly worse in patients compared to control, dysphagia was mostly due to aperistalsis. All progressive systemic sclerosis patients showed the typical esophageal manometry pattern of lower esophageal sphincter pressure and diminished amplitude with aperistalsis. Gastroesophageal reflux was detected in 83% of patients with progressive systemic sclerosis. Moreover, all 24-hour pH monitoring variables were significantly worse in group I.
  
  
  CONCLUSIONS
  Patients with progressive systemic sclerosis usually present with heartburn, dysphagia and regurgitation. Esophageal manometry typically shows lower pressure and aperistalsis. Gastroesophageal reflux is frequent.
