Guide To Treating Esophageal Achalasia

Pneumatic Dilation

Pneumatic dilation is an outpatient technique performed by an endoscopist where the lower esophageal sphincter is forced open by a balloon. During pneumatic dilation, the doctor threads a catheter attached to a deflated balloon down into the stomach. Using an X-ray for guidance, they make sure the balloon is positioned over the LES then inflate the balloon until it is about thirty to forty millimeters in diameter. This forces the muscle fibers in the esophagus to stretch and allows food to pass down into the stomach. The patient can return for more treatment if the first session doesn’t relieve their symptoms.
