title: [Update on non-variceal gastrointestinal bleeding].
abstract: This article summarizes the main studies in the field of non-variceal gastrointestinal bleeding reported in the last American Congress of Gastroenterology (Digestive Disease Week) in 2013. Some of these studies have provided new knowledge and expertise in areas of uncertainty. In this context and among other findings, it has been reported that the administration of a proton pump inhibitor (PPI) prior to endoscopy or the early performance of endoscopy-within 6 hours of admission in patients with upper gastrointestinal bleeding (UGIB) (or colonoscopy within 24 hours in patients with lower gastrointestinal bleeding)-does not improve the prognosis of the event. It has also been reported that oral administration of a PPI after endoscopic hemostasis may produce a similar outcome to that of intravenously administered PPI in patients with upper gastrointestinal bleeding (UGIB). In the field of endoscopic therapy, the use of radiofrequency ablation for antral vascular ectasia is of interest. Regarding UGIB and nonsteroidal antiinflammatory drugs (NSAIDs), new data confirm the risk of cardiovascular events by stopping treatment with acetylsalicylic acid (ASA) after an episode of UGIB, the increased risk of UGIB when associating gastrotoxic drugs, and the need to identify both the gastrointestinal and cardiovascular risks of each NSAID and coxib when prescribing these agents. Finally, there is evidence that both environmental and genetic factors are involved in individual susceptibility to gastrointestinal bleeding.
