Esophageal manometry
Alternative names:
esophageal function studies; esophageal motility studies
Normal values:
The LES pressure is normal and relaxes during a swallow. The pattern of muscle contractions is systematic and coordinated during a swallow.
What abnormal results mean:
Abnormal results may indicate achalasia (a failure of LES relaxation, causing the esophagus to become dilated and filled with retained food), diffuse esophageal spasm, and lack of muscle coordination.
Additional conditions under which the test may be performed:
