107 uncovered versus covered self-expandable metal stents in palliative endoscopic treatment of malignant gastric outlet obstruction: a large multicenter randomized trial in west japan

The pathogenesis of gastric outlet obstruction (GOO) mainly involves extrinsic tumors (i.e. pancreatic carcinomas) or intrinsic tumors (i.e. gastric carcinomas). Self-expandable metal stents (SEMSs) are an effective treatment option for GOO. However, stent dysfunction due to tumor ingrowth is a frequent problem with uncovered SEMSs, while covered SEMSs are prone to migration. The aim of this study was to compare uncovered and covered SEMSs for palliation of malignant GOO.
