nutcracker oesophagus
Diagram of
esophageal motility study for nutcracker esophagus. The image on the left is a schematic of the esophagus and three pressure recordings are taken: at the upper esophagus, lower esophagus and lower esophageal sphincter. The graph at the top indicates the time of two swallows. The disorder is peristaltic, with high pressure esophageal contractions exceeding 180 mmHg. The contractile waves have a long duration exceeding 6 seconds. -- Samir धर्म 09:00, 11 September 2006 (UTC)
nicht verwechseln mit: Hypercontracting (nutcracker) esophagus is a motility disorder of the esophagus. This condition is primarily diagnosed with manometry with high intra-esophageal pressure and normal peristalsis. Most patients will have a normal barium swallow.
Hypercontracting esophagus ("nutcracker esophagus") differs from diffuse esophageal spasm (corkscrew esophagus).
Epidemiology
Hypercontracting esophagus occurs in 10% of patients with non-cardiac chest pain.
Associations
Clinical presentation
Presentation includes chest pain, dysphagia, and gastro-esophageal reflux disease.
Pathology
Etiology
Etiology is unknown but may be related to gastro-esophageal reflux or stress .
Radiographic features
Fluoroscopy
A barium swallow is usually normal. A minority of patients may demonstrate features of non-specific esophageal motility disorder .
