Abstract | BACKGROUND: AIM: METHODS: For this retrospective study, a total 77 patients who underwent secondary stent-in- stent self-expanding metal stent placement for primary stent malfunction in malignant gastric outlet obstruction were enrolled. We compared the effectiveness and complications of secondary covered and uncovered stents and explored the predictive factors for stent malfunction. RESULTS:
Stent-in- stent self-expanding metal stent placements were technically successful in all patients. Both groups also had comparable clinical success rates (covered stent, 87.2% and uncovered stent, 90.0%, P = 1.000). Stent malfunction rates (31.9% and 36.7% respectively, P = 0.805) and median patency time of stent (165 [95% confidence interval: 112-218] and 165 [95% confidence interval: 126-204] days, respectively, P = 0.358) were similar between secondary covered and uncovered stents. Longer patients' survival time (≥ 100 days) was associated with increased risk of stent malfunction (odds ratio: 4.598; 95% confidence interval: 1.473-14.355; P = 0.009). CONCLUSIONS:
