What are the main tests for esophagitis?

Patient's question:

What are the examination items for esophagitis

Doctor's answer:

The examination items for esophagitis include:
1. Gastric-esophageal isotope scan: This test can directly detect reflux and has quantitative significance. The patient lies on their side, takes a radioactive labeled substance, and performs actions that increase intra-abdominal pressure. During the gastric-esophageal scan, if radioactive flashing is present in the esophagus, it indicates the presence of gastroesophageal reflux.
2. Barium meal X-ray esophagogram is a routine examination that must be performed for any esophageal disease, but it often shows no abnormalities in patients with reflux esophagitis, with a positive rate not exceeding 50%. Even in patients with typical symptoms, only 70% exhibit reflux phenomena on X-ray.
