What to check for esophagitis?

The most common methods to detect esophagitis include endoscopy, barium radiography, esophageal pH monitoring, etc.

Endoscopy

is to insert a tube with a camera into the patient's esophagus, so that doctors can directly observe the esophageal mucosa, which is the main method of diagnosing esophagitis.

2. Barium radiography

is to observe the flow of barium in the esophagus by swallowing paste-like barium sulfate and using X-ray irradiation to determine whether there is inflammation in the esophagus.

3. Esophageal pH monitoring

For patients suspected of reflux esophagitis, esophageal pH monitoring can help determine whether there is evidence of acid reflux. This method is to place a sensor in the esophagus to measure the pH value in the esophagus to determine whether acid reflux and the frequency of reflux.
