title: Endoscopic therapy for upper gastrointestinal bleeding.
abstract: Upper gastrointestinal bleeding (UGIB) is one of the most common medical emergencies and remains a major cause of morbidity and mortality among patients. Although initially employed diagnostically, endoscopy has steadily replaced surgery as a first-line treatment in all but the haemodynamically unstable patient. A vast selection of techniques and devices are now available to the dedicated therapeutic endoscopist, including injection therapy, electrical or thermal coagulation and mechanical banding or clipping. The use of endoscopic ultrasound for targeting treatment is increasing and the development of new technologies, such as capsule endoscopy, is likely to play an important role in future protocols. However, despite numerous randomized controlled trials and meta-analyses comparing the efficacy of different endoscopic interventions, the implementation of obtained results into treatment regimes has so far failed to impact significantly on overall UGIB mortality, which remains stubbornly at 10-14%. Reducing this continues to be one of the main challenges facing the therapeutic endoscopist.
