Abstract
Superior mesenteric artery syndrome (SMAS) is a rare condition in which the superior mesenteric artery (SMA) impinges on the third portion of the duodenum leading to symptoms of gastric outlet obstruction.1 When conservative management fails, surgical intervention may be required. In patients who are not surgical candidates or who decline surgery, EUS-guided gastroenterostomy (EUS-GE) using a cautery-enhanced lumen-apposing metal stent (LAMS) has been reported as a safe and effective option, but there is otherwise a paucity of data on the approach.
