Simultaneous combined balloon-occluded retrograde transvenous obliteration and partial splenic embolization for gastric fundal varices.

BACKGROUND

We previously reported the techniques and usefulness of simultaneous combined balloon-occluded retrograde transvenous obliteration (B-RTO) and partial splenic embolization (PSE), based on the hypothesis that concomitant PSE can diminish the increase in portal venous pressure after B-RTO.

OBJECTIVE

After experiencing more cases and performing longer-term follow-up, we re-evaluated the efficacy of simultaneous combined B-RTO and PSE for gastric fundal varices (GVs).

METHODS

We performed B-RTO in 36 consecutive patients treated for GVs from 2005 to 2013. Twenty-three patients underwent simultaneous combined B-RTO and PSE (Group 1) and 13 underwent B-RTO monotherapy (Group 2). The outcomes were retrospectively evaluated.

RESULTS

There were no significant differences in baseline characteristics between the two groups except that the splenic volumes were larger in Group 1 than 2. B-RTO was technically successful in 21 of 23 patients (91.3%) in Group 1 and in 12 of 13 patients (92.3%) in Group 2. In all patients with ruptured GVs (six in Group 1 and five in Group 2), complete hemostasis was obtained by B-RTO. Exacerbation of esophageal varices was significantly less frequent in Group 1 than 2 (p = 0.0017).

CONCLUSION

Concomitant PSE with B-RTO may contribute to prevention of the exacerbation of esophageal varices after B-RTO.
