New Techniques to Control Gastrointestinal Bleeding.

For decades, the mainstay of endoscopic hemostasis for a wide variety of gastrointestinal bleeding etiologies was limited to a few tools and techniques, including epinephrine injection, thermal probes, and through-the-scope hemostatic clips. Several novel approaches have recently emerged to control acute gastrointestinal hemorrhage. The concepts behind these approaches are diverse, ranging from upgrading current techniques (eg, over-the-scope clips and endoscopic ultrasound-guided treatment of gastric varices) to developing new technologies (eg, hemostatic powders) and repurposing current tools (eg, Doppler endoscopic probe). This article presents an evidence-based review of the major advancements in endoscopic hemostasis techniques.
