Abstract
Esophageal dilation is an important therapeutic strategy in patients with esophageal motility disorders. Patients with achalasia have for many years benefited from pneumatic dilation as a definitive form of therapy, which is superior to botulinum toxin injection and equivalent in efficacy to surgical myotomy. Optimal performance of pneumatic dilation ensures maximum efficacy and reduced complication of perforation. Esophageal dilation also plays a crucial role in esophagogastric junction outflow obstruction due to strictures or prior surgical interventions as well as in esophageal hypercontractile states such as spastic disorders or in those with nonobstructive dysphagia. In this section, we will review the clinical evidence of esophageal dilation in achalasia, esophagogastric junction outflow obstruction, esophageal spastic disorders and in patients with dysphagia and nonobstructive dysphagia. We will outline specific techniques currently recommended and employed in esophageal dilations for these disorders and provide relative efficacy to other forms of therapy.
