[0002] The causes of upper gastrointestinal bleeding include gastrointestinal ulcers, esophageal varices, gastritis / acute gastric mucosal lesions, upper gastrointestinal malignant tumors, esophageal cardia laceration syndrome and other reasons. In order to clarify the cause and carry out treatment, it is necessary to use a gastrointestinal endoscope to examine and stop bleeding. When the amount of bleeding is large, the blood will form a huge clot with gastric acid and other body fluids, blocking the endoscopic field of view and lesions.
