Esophageal Pressure Propagation Examination
Esophageal manometry examination plots motility function of the esophagus plotting a clear swallowing and peristalsis movement which would aid in assessing patients with feelings of globs or distenstion in the chest, dysphagia, and/or severe chest pain.
Symptoms of propagation disorder shown in esophageal pressure wave
Achalasia (cardiospasm)
No lower esophageal sphincter (LES) relaxation is observed. Elevated pressure in both esophagus and LES is seen, as well as a rise in pressure concurrent with a wet swallow (WS).
GERD
Transient LES relaxation along side impaired peristalsis can be observed.
Hypercontractile (Nutcracker) Esophagus
Similar motion to a healthy person except the contraction pressure of the peristalsis can reach abnormally high numbers above 200mmHg, causing immense chest pain.
Sliding Hiatal Hernia
Compared to normal LES, a seperation of wave forms can be observed in patients with Hernia. This can be recorded by placing the pressure sensor in the LES and pulling through towards the esophagus. The length of the LES is elongated as well where a normal LES should have the value of around 2~4cm in length and 15~30mmHg of pressure.
