Abstract Endoscopic ultrasound (EUS) has evolved from a purely diagnostic procedure to one with therapeutic capabilities. One of the most challenging therapeutic intervention for endosonographers is EUS‐guided pancreatic drainage. The development of this technique has allowed access and drainage of the main pancreatic duct after failed endoscopic retrograde pancreatography and can avoid invasive procedures such as surgical and percutaneous interventions. This review discusses the indications, technique, challenges, and an algorithmic approach to EUS‐guided pancreatic drainage.

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.
