title: Results of pneumatic dilatation in patients with dysphagia after antireflux surgery.
abstract: BACKGROUND
  The mechanisms and treatment of persistent dysphagia after antireflux surgery are not well established. The results of pneumatic dilatation were evaluated in a retrospective study.
  
  
  METHODS
  Sixteen patients were reviewed. All had severe and persistent postoperative dysphagia evaluated by oesophageal manometry before pneumatic dilatation.
  
  
  RESULTS
  Seven patients had one dilatation and nine had two dilatations. There was no complication and no relapse of reflux symptoms. Results were satisfactory in nine patients (mean(s.e.m.) follow-up 19.2(6.9) months) and poor in seven, who required revisional surgery. Age, time since operation and weight loss were not related to the outcome. Thirteen patients had abnormal manometry with an 'achalasia-like' motor pattern in four. Lower oesophageal sphincter (LOS) pressure, LOS relaxation and oesophageal contraction amplitude were similar in the two groups. The only difference was in the percentage of normal peristaltic contractions (mean(s.e.m.) 82.2(11) versus 39.1(13.8) per cent for satisfactory and poor results respectively; P < 0.05).
  
  
  CONCLUSIONS
  In this retrospective study pneumatic dilatation was effective and safe in nine of 16 patients with dysphagia following antireflux surgery. Peristalsis was normal in eight patients, in seven of whom it was associated with satisfactory results.
