Can stomach trouble not do gastroscope

Gastroscopy is

a method of inserting a gastric tube into the stomach to observe the gastric mucosa and sampling for pathological examination. It can provide more accurate results than other non-invasive examinations and is of great significance for the differential diagnosis of some stomach diseases. Gastroscopy is still a commonly used diagnostic method for stomach diseases with atypical symptoms, unclear etiology or clear pathological diagnosis. However, if the patient's symptoms are typical and the diagnosis can be made by some non-invasive examination methods, gastroscopy can generally be omitted.
