In this disease, the muscle at the bottom of the esophagus does not open to release food into the stomach. Food collects in the esophagus instead of moving into the stomach.
A disorder of the esophagus in which the lower esophageal sphincter does not relax. The lower esophageal sphincter (LES) is continuously contracted resulting in chest pain and symptoms of heartburn. This causes dilation of the esophagus as well as difficulty passing food into the stomach.
A condition characterised by lack of normal relaxation of the valve at the lower end of the gullet, which should occur during swallowing
a rare disorder of the esophagus in which the muscle at the end of the esophagus does not relax enough for the passage to open properly.
A disease of the esophagus caused by the abnormal function of nerves and muscles of the esophagus that makes swallowing difficult. There may sometimes be chest pain. Regurgitation of undigested food can occur, as can coughing or breathing problems due to entry of food into the lungs. The underlying problems are weakness of the lower portion of the esophagus and failure of the lower esophageal sphincter to open and allow passage of food. Achalasia may occur at any age but is predominantly a disease of young adults. Diagnosis is made by an X-ray, endoscopy , or esophageal manometry (to measure the pressure in the esophagus). Treatment includes medication, dilation (stretching) to widen the lower part of the esophagus, and surgery to open the lower esophagus. A fairly recent approach involves injecting medicines into the lower esophagus to relax the sphincter. See the entire definition of Achalasia
An uncommon disorder of the esophagus causing difficulty in swallowing. The muscle at the end of the esophagus does not relax enough for food to pass. This condition can be diagnosed by esophageal manometry.
The esophageal sphincter failing to relax properly, making it difficult to swallow. Treatable with da Vinci Heller Myotomy.
Motility Disorder Of The Oesophagus
A condition that develops when the lower esophageal sphincter fails to dilate and ingested materials cannot enter the stomach.
Achalasia, also known as esophageal achalasia, achalasia cardiae, cardiospasm, dyssynergia esophagus, and esophageal aperistalsis, is an esophageal motility disorder. In this disorder, inappropriate contraction of the smooth muscle layer of the esophagus leads to reduced peristalsis (muscular ability to move food down the esophagus) and failure of the lower esophageal sphincter (LES) to relax properly in response to swallowing. The most common form is primary achalasia (with no underlying cause), but a small proportion is due to esophageal cancer or (in South America) Chagas disease.
