Opinion statement

Esophageal dilation is the treatment of choice for most patients with esophageal dysphagia (functional and mechanical). Multiple forms of esophageal dilators are available. Mechanical dilators (guidewire/nonguidewire assisted) are the major forms of dilators used. Balloon dilator use has increased but they offer only a marginal advantage over traditional mechanical dilators at a greatly increased cost (2° to single use). Comparative trials are biased in favor of balloon dilators, but balloon dilators are not indicated for empiric dilation for dysphagia. Empiric dilation for solid food dysphagia is still controversial. Dilation is rarely associated with complications and is rarely contraindicated unless previous dilation attempts have been unsuccessful. Special circumstances such as caustic strictures, radiation stricture, and dysphagia associated with eosinophilic esophagitis should engender cautious dilation. Attention to detail about placement of guidewires and stricture type are still critical for safety. Predilation barium studies are not needed in all patients but should be employed if the endoscope is not able to pass the stricture and stricture length and angulation are unknown. Intralesional steroids and proton pump inhibitor therapy are important adjuvant treatments for resistant strictures and reflux associated strictures. Balloon dilation for achalasia is still a viable alternative, but it is likely to decrease in usage with the advent of more widespread laparoscopic myotomy.
