Nutcracker esophagus is a condition associated with very high pressures (greater than 180 mm Hg) that happen in the esophagus during the swallowing process. These elevated pressures may cause poor swallowing of both solid and liquid foods.
One of the major causes of nutcracker esophagus is gastroesophageal reflux disease. It can affect everyone, although it is more frequently seen in patients in their 60s and 70s.
Chest pain, heartburn and dysphagia (difficulty swallowing) are the most common symptoms of nutcracker esophagus. The chest pain can be intermittent and not related to food intake. Therefore it needs to be differentiated from cardiac chest pain. Although nutcracker esophagus can sometimes produce obstructive symptoms, the esophagus is not physically blocked.
As with other esophageal motility disorders, high-resolution manometry and a videoesophagram are essential to make the diagnosis and differentiate nutcracker esophagus from other disorders with similar symptoms. An upper endoscopy might also be necessary to rule out other causes of chest pain and dysphagia, such as chronic gastroesophageal reflux disease or achalasia.
