With mortality due to gastrointestinal (GI) bleeding remaining stable, the focus on endoscopic hemostasis has been on improving other outcomes such as rebleeding rate, need for transfusions, and need for angiographic embolization or surgery. Over the past few years, a number of devices have emerged to help endoscopically assess and treat bleeding GI lesions. These include the Doppler endoscopic probe, hemostatic powder, and over-the-scope clip. Also, new applications have been described for radiofrequency ablation. In this article, we will discuss these evolving tools and techniques that have been developed, including an analysis of their efficacy and limitations.

Endoscopic injection sclerotherapy (EIS) is a useful prophylactic hemostatic procedure for esophageal varices. However, injecting sclerosing agents into blood vessels is technically challenging and often ineffective. Gel-immersion EIS (GI-EIS) may facilitate easier intravascular sclerosing agent injection by dilating the varices and enhancing scope stability by maintaining low intra-gastrointestinal pressure.

Department of Hepatology and Gastroenterology, CHU Saint-Pierre, Brussels, Belgium (Jennifer Aoun, Pierre Eisendrath).
Background: Various endoscopic treatment options are available for managing colonic diverticular bleeding (CDB). We conducted a systematic review and meta-analysis to assess the effectiveness of these endoscopic interventions in achieving hemostasis in patients with CDB, focusing on early rebleeding rate (ERR) within 30 days.
Methods: A systematic literature search of the PubMed and Cochrane Library databases was performed for articles published between January 2008 and December 2023.

Introduction And Importance: Dieulafoy's lesion is a rare but serious cause of gastrointestinal bleeding, typically affecting older adults. It involves an aberrant arteriole eroding the gastric mucosa, resulting in severe, recurrent bleeding that poses diagnostic and management challenges. We present a case report of massive gastrointestinal hemorrhage with hemodynamic instability associated with a Dieulafoy's lesion.
