What is the difference between barium meal and gastroscope?

The difference between barium meal and gastroscopy lies in different examination methods, different observation clarity and different clinical significance.

1. Different examination methods

barium meal examination requires patients to take barium agent first, and then observe the barium agent flow under X-ray irradiation to diagnose gastrointestinal related diseases. Gastroscopy is an invasive examination, doctors will insert gastroscope into the patient's stomach and duodenum, and observe the upper digestive tract mucosa through the camera to diagnose related diseases.

2. Different observation clarity

barium meal examination belongs to plane examination, and the observation of gastric mucosa is relatively poor. Gastroscopy examination is more intuitive, and the observation of gastric mucosa is clearer.

3. Different clinical significance

barium meal belongs to diagnostic examination, while gastroscopy is both diagnostic examination and therapeutic examination.
