Gastroscopy is necessary for clarifying digestive system diseases as it can observe the mucosa of the esophagus, stomach, and duodenum and determine whether there is inflammation or space occupation.
The stomach is a hollow organ, and it is difficult to observe local lesions through imaging and ultrasonography. Gastroscopy, however, involves inserting a gastroscope through the oral cavity, which allows for simple and direct observation of the esophagus, stomach and duodenal mucosa, to see if there is any damage and whether there are polyps and tumors on its surface, and to clarify the presence of digestive disorders, and is therefore necessary for gastroscopic examination.
At the same time, gastroscopy is very helpful in guiding the treatment of esophageal, gastric and duodenal diseases, so gastroscopy is very necessary, and it is recommended to listen to the advice of professional doctors whether to carry out gastroscopy.
