Gastroscopy can be performed using barium meal and capsule endoscopy instead. Gastroscopy is one of the most common tests for stomach disorders, and has diagnostic and identification significance for a wide range of stomach disorders. Since gastroscopy is an invasive procedure, many people cannot tolerate the pain caused by the procedure, so other methods can be used instead. Barium meal is more common in the examination of gastric diseases, this examination is a non-invasive examination, the impact on the human body will be relatively less, barium meal can only observe the state of the stomach body, for the preliminary diagnosis of gastric diseases, can not be extracted from the living tissue, for the tumor can not be diagnosed for the nature of the good and the bad, compared with the gastroscope effect will be relatively poor. Capsule endoscopy can reduce the sense of fear and cause relatively less damage to the digestive system, not only can observe the situation in the stomach, but also can observe the situation in the intestines at the same time, but it can’t extract the biopsy tissue when it finds a suspicious mass, and the cost is relatively high.
