Abstract:
Endoscopic management of gastric outlet obstruction includes balloon dilation, enteral stenting, and endoscopic ultrasound-guided gastroenterostomy (EUS-GE) to relieve mechanical blockage and reestablish per oral intake. Based on the degree of obstruction, patients may experience debilitating symptoms that can quickly lead to malnutrition and delays in chemotherapy. Compared with surgery, minimally invasive endoscopic options can provide similar clinical outcomes with fewer adverse events, faster resumption of oral feeding, and shorter hospitalizations. EUS-GE with a lumen-apposing metal stent has revolutionized treatment, especially in individuals who are not ideal surgical candidates. This article aims to describe endoscopic treatment options and future considerations.
