Progress in new hemostasis techniques for acute upper gastrointestinal bleeding

Acute upper gastrointestinal bleeding (AUGIB) is one of the most common acute and critical illnesses in the emergency department. It mainly refers to gastrointestinal bleeding above the Treitz ligament, and the mortality rate is about 2%-10%. The main clinical manifestations are hematemesis and/or hematochezia. The diagnosis is mainly based on clinical manifestations combined with laboratory and imaging findings. Due to the rapid onset and severe nature of the condition, there are various treatment methods according to different causes. This article reviews the diagnosis and treatment of acute upper gastrointestinal bleeding.
