Diffuse or Distal esophageal spasm (DES) is an uncommon esophageal motility disorder causing chest pain and/or dysphagia.  
Diffuse or Distal esophageal spasm (DES) is an uncommon esophageal motility disorder causing [[chest pain]] and/or [[dysphagia]]. DES was first described by Osgood, in 1889 in 6 patients presenting with [[chest pain]] and [[dysphagia]]. Creamer et al. (1958) made the first [[Esophageal motility study|manometric]] descriptions of DES. Development of high resolution esophageal [[Esophageal motility study|manometry]] in 2000 has led to classification of esophageal motility disorders. Diffuse esophageal spasm can be classified as primary or secondary based on presence or absence of other disease associated with it. The exact pathogenesis of DES is not fully understood. Current high-resolution [[Esophageal motility study|manometric]] studies suggests impairment of inhibitory [[Neuron|neurons]]. These inhibitory [[Neuron|neurons]] use [[nitric oxide]] (NO) as [[neurotransmitter]]. Exact cause of diffuse esophageal spasm is unknown. However, may be caused by consequence of various diseases and secondary to conditions like compression of [[Nerve|nerves]] within esophageal wall, [[inflammation]] of the esophagus, stricture, [[Gastroesophageal reflux disease|GERD]], psychological conditions like [[anxiety]] or [[depression]]. Diffuse esophageal spasm must be differentiated from other [[diseases]] that cause [[dysphagia]], [[chest pain]] and [[weight loss]] such as [[Angina|angina,]] [[reflux esophagitis]], [[esophageal carcinoma]], [[systemic sclerosis]], [[Esophageal spasm|nutcracker esophagus]], hypertensive LES, [[Esophageal web|esophageal web/stricture]], [[pseudoachalasia]], [[stroke]], [[esophageal candidiasis]], [[Chagas disease]] etc. Common risk factors in the development of Diffuse Esophageal Spasm include: Age (60-80 years), [[obesity]], [[mitral valve prolapse]], presence of [[Gastroesophageal reflux disease|GERD]], [[Hypertension]], [[anxiety]] or [[depression]], and drinks (eg. red wine, very hot or cold liquid or fluid). If left untreated, most patients  are symptom free over the course of time. Very few cases report of progression to [[achalasia]] and nut cracker esophagus. The diagnostic study of choice for DES is [[Esophageal motility study|manometry]]. An x-ray of esophagus after [[Esophagogram|barium swallow]] ([[esophagogram]]) is the next best test to support [[Esophageal motility study|manometric]] diagnosis. The mainstay of treatment for DES is medical therapy with [[Calcium channel blocker|calcium channel blockers]], and/or [[Tricyclic antidepressant|tricyclic antidepressants]].

Historical Perspective

Esophagus was described by Vasalius in 1543. Diffuse esophageal spasm was first described by Osgood in 1889 in 6 patients presenting with chest pain and dysphagia. Development of high resolution esophageal manometry in 2000 has led to classification of esophageal motility disorders.

Classification

Diffuse esophageal spasm can be classified as primary or secondary based on its association with other diseases.

Pathophysiology

The exact pathogenesis of DES is not fully understood. Current high-resolution manometric studies suggests impairment of inhibitory neurons. These inhibitory neurons use nitric oxide (NO) as neurotransmitter.

Causes

Exact cause of diffuse esophageal spasm is unknown. However, may be caused by consequence of various diseases and secondary to conditions like compression of nerves within esophageal wall, inflammation of the esophagus, strictures, GERD, and psychological conditions like anxiety or depression.

Differentiating Diffuse esophageal spasm from Other Diseases

Diffuse esophageal spasm must be differentiated from other diseases that cause dysphagia, chest pain and weight loss such as angina, reflux esophagitis, esophageal carcinoma, systemic sclerosis, nutcracker esophagus, hypertensive LES, esophageal web/stricture, pseudoachalasia, stroke, esophageal candidiasis and Chagas disease etc.

Epidemiology and Demographics

Diffuse esophageal spasm is relatively uncommon disease with incidence of 1 per 100,000 in the USA. DES affects all age groups. There is no racial predilection to DES.

Risk Factors

Common risk factors in the development of diffuse esophageal spasm include age (60-80 years), obesity, mitral valve prolapse, presence of GERD, hypertension, anxiety or depression, and drinks (eg. red wine, very hot or cold liquid or fluid).

Screening

There is insufficient evidence to recommend routine screening for DES.

Natural History, Complications, and Prognosis

If left untreated, most patients remain asymptomatic over the course of time. Very few cases report progression to Achalasia and nut cracker esophagus.

Diagnosis

Diagnostic Study of Choice

The diagnostic study of choice for DES is manometry.

History and Symptoms

The hallmark of DES is esophageal dysphagia for both solids and liquids and chest pain. Symptom onset is sudden, intermittent and non-progressive in nature. Chest pain usually retrosternal in location, which is intense and squeezing in nature and may be mistaken for Angina. Difficulty swallowing, is sometimes related to specific substances like red wine, very cold or hot liquid.

Physical Examination

Patients with primary diffuse esophageal spasm usually appear normal. Physical examination of patients with DES is usually remarkable for findings related to secondary diseases.

Laboratory Findings

There are no diagnostic laboratory findings associated with DES.

Electrocardiogram

There are no ECG findings associated with DES.

X-ray

An x-ray of esophagus after barium swallow (esophagogram) is the next best test to support manometric diagnosis.

Ultrasound

There are no echocardiography/ultrasound findings associated with DES.

CT scan

Chest CT scan may be helpful in the diagnosis of DES. Findings on CT scan suggestive of DES include esophageal wall thickening.

MRI

There are no MRI findings associated with diffuse esophageal spasm.

Other Imaging Findings

Endoscopy may be helpful in the diagnosis of DES to exclude other esophageal lesion causing chest pain.

Other Diagnostic Studies

24-hour esophageal pH monitoring may be helpful in the diagnosis of secondary DES.

Treatment

Medical Therapy

The mainstay of treatment for DES is medical therapy with calcium channel blockers, and/or tricyclic antidepressants.

Surgery

The mainstay of treatment for DES is medical therapy. Surgery is usually reserved for patients with manometrically proven, symptomatic and those cases refractory to medical therapy.

Primary Prevention

There are no established measures for the primary prevention of diffuse esophageal spasm.

Secondary Prevention

There are no secondary preventive measures available for insulinoma.
