Upper gastrointestinal (GI) bleeding is a common cause for Emergency Department and hospital admissions and has significant mortality and morbidity if it remains untreated. Upper endoscopy is the key procedure for both diagnosis and treatment of acute upper GI bleeding. The aim of this article is to review the optimal timing of endoscopy in patients with acute upper GI bleeding. The cost-effectiveness and the influence of urgent or emergent endoscopy on patients’ outcomes are discussed. Also, we compare and contrast the available evidence and guidelines regarding the recommended time points for performing endoscopy in different clinical settings.
