Long-Term Outcomes of Balloon-Occluded Retrograde Transvenous Obliteration for the Treatment of Gastric Varices: A Comparison of Ethanolamine Oleate and Sodium Tetradecyl Sulfate.

PURPOSE: This study was performed to compare the long-term outcomes of balloon-occluded retrograde transvenous obliteration (BRTO) for gastric varices using ethanolamine oleate (EO) and sodium tetradecyl sulfate (STS).

METHODS: From January 2002 to June 2015, 142 patients underwent BRTO for the treatment of gastric varices using EO (n = 59) or STS (n = 83). We retrospectively reviewed the follow-up data related to the obliteration of gastric varices, rebleeding, and clinical complications. The cumulative recurrence rates of gastric varices after BRTO in each group were analyzed using the Kaplan-Meier method and compared using the log-rank test.

RESULTS: The median follow-up periods were 23.9 (range 0.2-170.7) months in the BRTO with EO group and 19.9 (range 0.2-84.7) months in the BRTO with STS group. Technical success was achieved in 53 of 59 (89.8%) cases in the BRTO with EO group and 80 of 83 (96.4%) cases in the BRTO with STS group. The clinical success rates were 94.9% (56/59) in the BRTO with EO group and 96.4% (80/83) in the BRTO with STS group. The cumulative 1-, 3-, and 5-year recurrence rates for gastric varices were 3.8, 9.4, and 9.4% in the BRTO with EO group and 1.3, 2.5, and 3.8% in the BRTO with STS group, respectively (p = 0.684).

CONCLUSIONS: BRTO using STS has comparable long-term outcomes to BRTO using EO for gastric varices.
