Abstract
Nine patients with severe symptoms of diffuse esophageal spasm and lower esophageal sphincter dysfunction who were unresponsive to medical therapy and bougienage dilatation were treated by forceful pneumatic dilatation. Treatment with pneumatic dilatation in eight of the nine patients produced a marked improvement in dysphagia and regurgitation (average follow-up of 37.4 months). Esophageal motility performed up to three years (average 12.4 months) after clinically successful pneumatic dilatation revealed a decrease in lower esophageal sphincter pressure from 34.0±4.0 mmHg (mean ± standard error) to 19.2±2.7 mm Hg (P<0.01). There were no significant changes in either the percentage of lower esophageal sphincter relaxation or the type of esophageal motor pattern. We conclude from this study that pneumatic dilatation is an effective form of therapy for a select group of patients with severe symptomatic diffuse esophageal spasm with lower esophageal sphincter dysfunction who are unresponsive to conventional medical therapy.
