Diffuse esophageal spasm (DES), also known as distal esophageal spasm, is a condition characterized by uncoordinated contractions of the esophagus, which may cause difficulty swallowing or regurgitation. In some cases, it may cause symptoms such as chest pain, similar to heart disease. In many cases, the cause of DES remains unknown.
CREST syndrome, also known as the limited cutaneous form of systemic sclerosis (lcSSc), is a multisystem connective tissue disorder.The acronym "CREST" refers to the five main features: calcinosis, Raynaud's phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasia.
Esophageal spasm is a disorder of motility of the esophagus. [2] There are two types of esophageal spasm: [2] Diffuse or distal esophageal spasm (DES), where there is uncoordinated esophageal contractions; Nutcracker esophagus (NE) also known as hypertensive peristalsis, where the contractions are coordinated but with an excessive amplitude.
Nutcracker esophagus is characterized by high-amplitude peristaltic contractions that are frequently prolonged and cause dysphagia and chest pain. [ 6 ] HLES (hypertensive lower esophageal sphincter) is a rare manometric abnormality seen among individuals with dysphagia, chest pain, gastroesophageal reflux , and hiatal hernia .
Many patients with nutcracker esophagus do not have any symptoms at all, as esophageal manometry studies done on patients without symptoms may show the same motility findings as nutcracker esophagus. [2] Nutcracker esophagus may also be associated with metabolic syndrome. The incidence of nutcracker esophagus in all patients is uncertain. [7]
Esophageal dysphagia is a form of dysphagia where the underlying cause arises from the body of the esophagus, lower esophageal sphincter, or cardia of the stomach, usually due to mechanical causes or motility problems.
Esophageal achalasia is an esophageal motility disorder involving the smooth muscle layer of the esophagus and the lower esophageal sphincter (LES). [5] It is characterized by incomplete LES relaxation, increased LES tone, and lack of peristalsis of the esophagus (inability of smooth muscle to move food down the esophagus) in the absence of ...
As of 2018, esophageal cancer was the eighth-most common cancer globally with 572,000 new cases during the year. It caused about 509,000 deaths that year, up from 345,000 in 1990. [8] [12] Rates vary widely among countries, with about half of all cases occurring in China. [2] It is around three times more common in men than in women. [2]
