Classification of DES

There is no established system for the classification of DES although it is categorized as one of the major disorders of Peristalsis according to The Chicago Classification v.3.0

Common risk factors in the development of Diffuse Esophageal Spasm include Age (60-80 years), presence of GERD, Hypertension, anxiety or depression, and drinks (eg. red wine, very hot or cold liquid or fluid).

The exact pathogenesis of DES is not fully understood. However, current high-resolution manometric studies suggest impairment of inhibitory myenteric plexus neuron. These neurons use nitric oxide (NO) as neurotransmitter. Hence, these patients may also have dysregulation of endogenous NO synthesis or/and degradation.

It is thought that [disease name] is the result of / is mediated by / is produced by / is caused by either [hypothesis 1], [hypothesis 2], or [hypothesis 3].
[Pathogen name] is usually transmitted via the [transmission route] route to the human host.
Following transmission/ingestion, the [pathogen] uses the [entry site] to invade the [cell name] cell.
[Disease or malignancy name] arises from [cell name]s, which are [cell type] cells that are normally involved in [function of cells].
The progression to [disease name] usually involves the [molecular pathway].
The pathophysiology of [disease/malignancy] depends on the histological subtype.
