Self-Expandable Metallic Stent in Malignant Gastroduodenal Outlet Obstruction: A Viable Alternative?

Aims Malignant gastroduodenal outlet obstruction (GOO) is commonly seen with distal gastric cancer and pancreatic adenocarcinoma with extension to the duodenum or stomach (1). Gastroenterostomy has been the mainly treatment strategy for this condition, however, is associated with high mortality and many patients are excluded from surgery because of poor medical condition (2). Self-expanding metallic stents (SEMS) are an increasingly used alternative. We aimed to evaluate the effectiveness and safety of this technique in palliation of malignant GOO.
