Interventional endoscopic ultrasonography (EUS) is currently becoming the less invasive therapeutic approach for the drainage of pancreatic fluid collections, of acute cholecystitis in patients unfit for surgery and for biliary drainage after failed endoscopic retrograde cholangiopancreatography. In addition, EUS-guided gastroenterostomy (EUS-GE) has recently emerged as a feasible procedure to treat patients with gastric outlet obstruction, as an alternative to surgery or to standard endoscopy when endoscopic stent placement is not possible. Prior animal studies have shown that the procedure is safe and can create a stable anastomosis. However, the major challenge in translating the results of the animal studies into clinical practice is represented by the proper identification of the distal duodenal or proximal jejunal loop to be accessed in order to create the anastomosis. Currently, there are three EUS-GE techniques available: the direct EUS-GE technique, assisted EUS-GE technique, and its variant called the EUS-guided double-balloon-occluded gastrojejunostomy bypass. The present review describes the current EUS-GE techniques, depicts the different procedural aspects of the procedure, and presents the clinical evidences available so far, with a focus on the future perspectives of this EUS-guided technique.
