Gastric Varix Clinical Trial
Official title:
A Pilot Study Evaluating Efficacy and Safety of Combined and Simultaneous Balloon-occluded Retrograde Transvenous and Endoscopic Obliteration of High-risk Gastric Varices
The aim of this pilot study is to evaluate the efficacy and safety of combined and simultaneous endoscopic variceal obliteration together with balloon occluded-retrograde transvenous obliteration (B-RTO) for the treatment of high-risk gastric varices
Although less frequent than esophageal varices, gastric varices constitute a severe and
potentially life threatening complication of portal hypertension. Various methods have been
described to treat gastric varices, including endoscopic and interventional radiology
techniques. Endoscopic variceal obliteration (EVO) is currently considered as standard of
care for the treatment of gastric varices in most centers. However, this technique is
associated with significant rebleeding rates and incomplete obliteration is observed in about
50% of patients. Alternatively, few centers also use an interventional radiology technique,
called balloon-occluded retrograde transvenous obliteration (B-RTO) to treat gastric varices,
which has been shown to be associated with less recurrence of gastric varices and high rates
of eradication of about 90%. Both techniques have their inherent weaknesses, such as frequent
incomplete eradication of varices and thromboembolic events for EVO, while data suggest that
B-RTO may aggravate esophageal varices.
The aim of this pilot study is to evaluate the efficacy and safety of combined and
simultaneous endoscopic variceal obliteration together with (modified) B-RTO. Stopping the
outflow of gastric varices by endovascular balloon occlusion may allow better endoscopic
visualization, blood stagnation and thus eradication of varices, while preventing
thromboembolic events. Furthermore, during study follow-up, the eradication rates and
recurrence of varices, short-term and long term complications, effects of the procedure on
portal pressures/hemodynamics and liver function will be evaluated.
