[Guidelines for the diagnosis and treatment of acute non-variceal upper gastrointestinal bleeding (2018, Hangzhou)].

Acute non-variceal upper gastrointestinal bleeding (ANVUGIB) is one of the most common medical emergencies worldwide. In 2009, the first edition of "Guidelines for the diagnosis and treatment of acute non-variceal upper gastrointestinal bleeding" was published in China. These guidelines were updated in 2015, which aimed to provide the standard diagnosis and management for patients with ANVUGIB. Based on the rapid development of multiple disciplines and latest understanding of ANVUGIB, this new edition of guidelines was therefore released for standardizing the diagnosis and management process of ANVUGIB.
