What benefit does the Heller Myotomy surgery have?

Heller Myotomy surgery (also known as Achalasia Surgery) is a treatment for the condition named Achalasia. Achalasia makes swallowing difficult because the muscles of around the lower part of the esophagus do not function properly. A Heller Myotomy involves cutting the muscle layers around the malfunctioning esophagus area and results in the benefit of allowing food to passage into the stomach and relief of common symptoms like indigestion, the feeling of food and liquids being stuck in the lower chest or regurgitation.
