Upper gastrointestinal bleeding is relatively common in clinical practice. The main diagnostic methods include gastroscopy, barium meal examination of the gastrointestinal tract, and DS imaging of the gastrointestinal tract, among others. If a patient experiences a large amount of bleeding at a rapid pace after upper gastrointestinal bleeding, it can lead to a drop in blood volume and hypovolemic shock, which can be life-threatening. In such cases, it is crucial to seek prompt medical treatment and use hemostatic drugs, and even endoscopic hemostasis or surgical intervention may be necessary to actively save the patient's life.
