Upper gastrointestinal bleeding is very common clinically. If the patient's respiratory and circulatory systems are stable, an esophagogastroduodenoscopy can be performed to further identify the bleeding site. Of course, it is also necessary to dynamically monitor blood tests and coagulation function, and pay attention to the patient's vomiting and rectal bleeding. The clinical treatment of upper gastrointestinal bleeding mainly involves transfusions to replenish blood volume and conservative medical treatment for hemostasis. If conservative medical treatment is not effective, surgical intervention can be considered.
