Endoscopic therapy for gastric varices.

Bleeding from gastric varices (GVs) is generally more severe than bleeding from esophageal varices (EVs), but is thought to occur less frequently. Although several recent developments in the agents and the techniques have improved the outcome of GV bleeds no consensus has been reached on the optimum treatment. Because the blood flow in the GVs is relatively large and the bleeding is rapid and often profuse endoscopic means of treating bleeding GVs are the treatments of choice. Endoscopic injection of cyanoacrylate glue is the treatment of choice for the control of active bleeding of gastric avarices and to prevent rebleeding. This article reviews the current endoscopic treatment modalities used in gastric variceal bleeding, and the primary and secondary prophylaxis of gastric variceal bleeding.
