Pneumatic Dilation. Pneumatic dilation is an endoscopic therapy for achalasia. An air-filled cylinder-shaped balloon disrupts the muscle fibers of the lower esophageal sphincter, which is too tight in patients with achalasia. How is pneumatic dilation performed? During an outpatient upper endoscopy, the endoscopist passes a catheter with a deflated balloon through the mouth and into the stomach. The balloon is centered over the lower esophageal sphincter and inflated with air.
