However, there is significant heterogeneity in how BRTO is performed, including how and how long to occlude the outflow venous shunt amongst other variables such as variceal size, flow rate, agent used, and preparation technique. We propose a method using foam sclerotherapy and reducing balloon occlusion to as little as 30\u00a0min, with assessment of the efficacy of this shorter balloon inflation time.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Retrospective single\u2010centre analysis of BRTO procedures between July 2015 and February 2019 for isolated gastric varices in a non\u2010acute setting, where inflation time was 2\u00a0h or less.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Six patients underwent BRTO with a short inflation time, with a mean age of 66\u00a0years. The median balloon inflation and thus 3% athoxysclerol foam contact time was 30\u00a0min (range 30\u201360\u00a0min). Four of the 6 patients showed complete resolution of varices, while 2 of the 6 showed a partial response. Mean follow\u2010up was 27\u00a0months. There were no patients who did not show a response to treatment and no episodes of clinically significant upper gastrointestinal bleeding.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>This technique using a shortened balloon occlusion time resulted in complete or partial clinical and technical success in all patients and suggests that the threshold for initiation of gastric variceal thrombosis may be below 30\u00a0min. This timepoint may provide a balance between adequate balloon inflation, angiography room efficiency and hospital resource allocation with resultant procedural cost
