Endoscopic hemostatic methods for gastrointestinal bleeding are: 1, upper gastrointestinal variceal rupture bleeding: usually take ligature or intravenous injection of sclerosing agent combined with tissue glue, such as intraesophageal injection of intravenous sclerosing agent and ligature, gastric fundus for tissue glue injection, etc. Precise treatment of varicose veins, i.e. vein sealing by endoscopic injection of tissue glue, plays the role of blocking varicose veins. 2, bleeding from non-varicose ulcers in the upper gastrointestinal tract: high frequency electrocoagulation, laser, argon and hemostatic clips are usually taken to stop bleeding.
