Achalasia

What is achalasia?

Achalasia is a rare disease of the muscle of the esophagus (swallowing tube). The term achalasia means "failure to relax" and refers to the inability of the lower esophageal sphincter (a ring of muscle situated between the lower esophagus and the stomach) to open and let food pass into the stomach. As a result, patients with achalasia have difficulty in swallowing food.

How does the normal esophagus function?

The esophagus has three functional parts. The uppermost part is the upper esophageal sphincter, a specialized ring of muscle that forms the upper end of the tubular esophagus and separates the esophagus from the throat. The upper sphincter remains closed most of the time to prevent food in the main part of the esophagus from backing up into the throat. The main part of the esophagus is referred to as the body of the esophagus, a long, muscular tube approximately 20 cm (8 in) in length. The third functional part of the esophagus is the lower esophageal sphincter, a ring of specialized esophageal muscle at the junction of the esophagus with the stomach. Like the upper sphincter, the lower sphincter remains closed most of the time to prevent food and acid from backing up into the body of the esophagus from the stomach.

The upper sphincter relaxes with swallowing to allow food and saliva to pass from the throat into the esophageal body. The muscle in the upper esophagus just below the upper sphincter then contracts, squeezing food and saliva further down into the esophageal body. The ring-like contraction of the muscle progresses down the body of the esophagus, propelling the food and saliva towards the stomach. (The progression of the muscular contraction through the esophageal body is referred to as a peristaltic wave.). By the time the peristaltic wave reaches the lower sphincter, the sphincter has opened, and the food passes into the stoma...

Dysphagia »

What is dysphagia?

Dysphagia is the medical term for the symptom of difficulty swallowing, derived from the Latin and Greek words meaning difficulty eating.

Mechanism of swallowing

Swallowing is a complex action.

  • Food is first chewed well in the mouth and mixed with saliva.
  • The tongue then propels the chewed food into the throat (pharynx).
  • The soft palate elevates to prevent the food from entering the posterior end of the nasal passages, and the upper pharynx contracts, pushing the food (referred to as a bolus) into the lower pharynx. At the same time, the voice box (larynx) is pulled upwards by muscles in the neck, and, as a result, the epiglottis bends downwards. This dual action closes off the opening to the larynx and windpipe (trachea) and prevents passing food from entering the larynx and trachea.
  • The contraction of the muscular pharynx continues as a progressing, circumfe...
