Clinical Trial: ComVi and D-type Stent in Malignant GOO
Study Status: Completed

Study Type: Interventional
Official Title: A Newly Designed Conformable Uncovered Versus Covered Self-expandable Metallic Stent for Palliation of Malignant Gastric Outlet Obstruction: a Prospective, Randomized Mult
Brief Summary: Covered self-expandable metallic stents (SEMS) have been used to prevent tumor ingrowth, a common complication of uncovered SEMSs. However, they have revealed a high incidence of stent migration in patients with unresectable malignant gastric outlet obstruction (GOO). A conformable covered SEMS was introduced to overcome both stent migration and tumor ingrowth. The aims of this study were to evaluate the clinical outcomes of newly designed conformable covered and uncovered SEMS for palliation of malignant GOO.

Current Primary Outcome: the stent patency time from stent insertion to restenosis due to stent malfunction or death [ Time Frame: Up to 1 years ]
Original Primary Outcome: Same as current
Current Secondary Outcome: stent malfunction (e.g., stent migration or occlusion due to tumor ingrowth/overgrowth) and the reintervention rate [ Time Frame: up to 1 years ]
Original Secondary Outcome: Same as current
