Combined endoscopic clipping and injection sclerotherapy for esophageal varices

Variceal Bleeding: Beyond Banding

Despite advances in the management of complications of portal hypertension, variceal bleeding continues to be associated with significant morbidity and mortality. While endoscopic variceal band ligation remains first line therapy for treating bleeding and high-risk non-bleeding esophageal varices, alternate therapies have been explored, particularly in cases of refractory bleeding. The therapies being explored include stent placement, hemostatic powder use, over-the-scope clips and others. For gastric variceal bleeding, endoscopic ultrasound-guided therapies have recently emerged as promising interventions for hemostasis. The aim of this article is to highlight these alternative therapies and their potential role in the management of gastric and esophageal variceal bleeding.

Endoscopic clipping for the management of gastrointestinal bleeding

Endoscopic clipping is a safe and effective technique for the treatment of various bleeding gastrointestinal lesions. Randomized controlled trials and a meta-analysis have shown comparable efficacy between clipping and conventional contact thermal therapy for definitive hemostasis of nonvariceal upper gastrointestinal hemorrhage. Clipping also seems to be efficacious for selected lower gastrointestinal bleeding lesions, such as diverticular bleeding and postpolypectomy bleeding. Proficiency in clip application and endoscopic identification of lesions that are amenable to clipping are key determinants of a successful outcome.
