Esophageal manometry is a diagnostic test that checks whether the esophagus is working normally. It gives information about the movement of food through the esophagus into the stomach.

The esophagus is a long, muscular tube that connects your pharynx to your stomach.

After swallowing food, the esophagus contracts and pushes food into your stomach. The food bolus is pushed through as a result of serial, rhythmic contractions of the esophagus.

This test provides evidence regarding: –

1. Force of esophageal musculature

2. Rate and rhythm (pattern) of contraction

In this procedure a thin, flexible tube (catheter) containing pressure sensors is passed through your nose, down your esophagus and into your stomach.

Common indications: 

a) Dysphagia with solids

b) Dysphagia with solids and liquids

c) Epigastric discomfort/ heartburn

d) Non-cardiac angina
