    Abstract:
    BACKGROUND & AIMS: Because gastric variceal bleeding is associated with a high mortality rate, its prophylaxis is expected to improve survival. We investigated the effectiveness of balloon-occluded retrograde transvenous obliteration (B-RTO) for the treatment of gastric fundal varices. METHODS: A prospective nonrandomized study was conducted. Prophylactic B-RTO was performed in 17 patients (B-RTO group), whereas the remaining 17 patients received no specific treatment (control). The nonbleeding rate, cumulative survival rate, and prognostic values of the patients were assessed. RESULTS: The respective nonbleeding rates at 1, 3, and 5 years were 100%, 100%, and 83% in the B-RTO group and 81%, 59%, and 39% in the control. The respective cumulative survival rates at 1, 3, and 5 years were 94%, 85%, and 39% in the B-RTO group and 71%, 41%, and 22% in the control. Both the nonbleeding rate and the cumulative survival rate of the B-RTO group were significantly higher than those of the control (P = .01 and .04, respectively). B-RTO was determined by multivariate analysis to be a significant factor for low bleeding rate (relative risk, 0.06; 95% confidence interval [CI], 0.004-0.79), whereas B-RTO (0.11; 95% CI, 0.03-0.44) and Child-Pugh class A (0.10; 95% CI, 0.03-0.39) were the significant factors for a low mortality rate, and the presence of hepatocellular carcinoma (5.68; 95% CI, 1.49-21.7) was the significant factor for a high mortality rate. CONCLUSIONS: Prophylactic B-RTO is effective in preventing gastric variceal rupture and consequently improves patient survival.
