Placement of a self-expandable metal stent is a palliative treatment of choice for patients with malignant gastric outlet obstruction (GOO). Although covering an enteral stent with a membrane almost solves the problem of tumor ingrowth, stent migration continues to be a major unresolved problem. Our aim was to evaluate the clinical efficacy of endoscopic clipping for prevention of covered stent migration in the treatment of malignant GOO.
