Outcomes of pneumatic dilation in achalasia: Extended follow‐up of more than 25 years with a focus on manometric subtypes

Abstract

Pneumatic dilation in achalasia is an effective therapy in the short term, but its effect wanes in the very long term. Young age at presentation, a high lower esophageal sphincter pressure, a narrow cardia, and an esophageal barium column of > 1 cm after PD are predictive factors for the need of repeated treatment.
