EUS-GE vs ES for Palliation of Gastric Outlet Obstruction

In this technique, the gastric wall and its adjacent small intestine are punctured by a needle to make a connection between the stomach and small intestine. Then a lumen-apposing metal stent is deployed at the puncture site to keep the stomach-small intestine connection open.

In this technique, under endoscopic visualization, a guidewire will be advanced through the obstructed part of the stomach. Then an enteral self-expandable metal stent will be deployed under direct endoscopic visualization and fluoroscopic guidance.
