How is esophageal diverticulum diagnosed?

The tests most commonly used to diagnose and evaluate esophageal diverticulum include:

Barium swallow: The patient swallows a barium preparation (liquid or other form) and its movement through the esophagus is evaluated using X-ray technology.

Gastrointestinal endoscopy: A flexible, narrow tube called an endoscope is passed through the gastrointestinal tract and projects images of the inside onto a screen.

Esophageal manometry: This test measures the timing and strength of esophagus contractions and muscular valve relaxations.

24-h pHmetry: A test to check for the presence of gastroesophageal reflux disease (GERD).
