- Abstract: Gastric outlet obstruction (GOO) can be caused by periampullary malignancies and often leads to a reduction in a patient’s quality of life. Recently, endoscopic ultrasonography-guided gastroenterostomy (EUS-GE) using a lumen-apposing self-expandable metal stent (LAMS) has been developed as a minimally invasive and durable endoscopic treatment for GOO. There are three types of EUS-GE technique: (1) the direct technique; (2) device-assisted techniques, such as a balloon catheter, nasobiliary drainage tube, and ultraslim endoscopy; and (3) EUS-guided double balloon-occluded gastrojejunostomy bypass. Previous reports of EUS-GE with LAMS have shown technical and clinical success rates (regardless of technique and etiology) of 87%–100% and 84%–100%, respectively. Studies comparing EUS-GE and surgical gastrojejunostomy have shown similar success rates, reintervention rates, and cost benefits, with a lower rate of early adverse events in EUS-GE. A comparison of EUS-GE and endoscopic enteral stent placement revealed similar technical success rates, but initial clinical success rate was higher and the rate of stent failure requiring reintervention was lower with EUS-GE.
