Historical Perspective

Discovery

• DES was first described by Osgood, in 1889 in 6 patients who presented with chest pain and dysphagia.

• Creamer (1954) made the first manometric descriptions of DES.

Landmark Events in the Development of Treatment Strategies

• In 2000, development of high resolution esophageal manometry has led to classification of esophageal motility disorders.

Pathophysiology

Pathogenesis

• The exact pathogenesis of DES is not fully understood. However, current high-resolution manometry 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. The final result is premature and rapidly propagated or simultaneous contraction of smooth muscles of distal esophagus.
