AIM: As for self-expandable metallic stents (SEMS) for malignant gastric outlet obstruction (GOO), some predictive factors of stent patency have been reported, although re-canalization of GOO by SEMS does not necessarily lead to favorable food intake. Therefore, we analyzed the predictive factors of oral food intake following SEMS placement. METHODS: A total of 97 consecutive patients in whom SEMS were placed for malignant GOO in five hospitals were included in this retrospective study. Clinical outcomes and predictive factors influencing solid food intake were analyzed. RESULTS: The technical and clinical success rates were 97.9% and 87.6%, respectively. The mean gastric outlet obstruction scoring system (GOOSS) improved from 0.39 to 2.24 after SEMS placement (P<0.01). The median eating period was 2.1 months (95% CI, 1.1-3.0 months), and the median survival time was 3.1 months (95% CI, 2.0-4.2 months). A Karnofsky performance status of ≤ 50 (odds ratio, 3.65; 95% CI, 1.17-13.1; P=0.03) and ascites (odds ratio, 3.28; 95% CI, 1.23-9.05; P=0.02) were identified as statistically significant independent poor predictive factors of solid food intake. CONCLUSION: SEMS is an effective treatment for patients with malignant GOO. Ascites and a poor performance status were poor predictive factors of solid food intake.
