[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.急性非静脉曲张性上消化道出血（ANVUGIB）是临床最常见的急危重症之一，为了指导国内的临床医师对ANVUGIB进行规范化诊治，我国在2009年发表了《急性非静脉曲张性上消化道出血诊治指南》，并于2015年进行了更新。随着各学科技术的飞速发展，近年来对于ANVUGIB又有了新的认识，因此在2018年对原有的指南再次进行更新，以期对ANVUGIB的临床规范化处理起到一定的指导作用。.
