Novel techniques for gastric variceal obliteration.

Acute hemorrhage related to gastric varices (GV) is more severe and often more difficult to immediately treat upon detection, leading to a poorer patient prognosis, as compared to esophageal variceal bleeding. Currently, the recommended treatment of bleeding GV is endoscopic cyanoacrylate injection and transjugular intrahepatic portosystemic shunt placement for endoscopic failures. Newer endoscopic (e.g. hemospray) and endosonographic (e.g. coil injection, glue obliteration, or combined coil and glue injection) techniques have been developed to offer an alternative treatment and improve patient outcome. The present article serves to review the endoscopic, endosonographic, and interventional radiological techniques used to treat GV and their clinical applications.
