Achalasia is a disorder that prevents food from moving through the esophagus, the tube that connects the mouth to the stomach. At the junction of the esophagus and stomach, there is a valve that regulates how much food enters the stomach. In achalasia the valve does not relax to allow for the proper entry of food into the stomach. This is due to the loss of peristalsis, the wavelike contractions that move food in a synchronous manner down to the stomach.
A loss of nervous innervation to the esophagus – a condition caused by cancer, infection, and hereditary factors – can also lead to achalasia. Common symptoms include chest pain that extends to the back, neck, and arms after eating, as well as coughing, difficulty swallowing, food regurgitation, heartburn, and weight loss.
The specialists at UT Southwestern Medical Center may perform one or more of the following procedures to diagnose achalasia:
