Video Summary

The transcript describes DubX, a through-the-scope exchangeable double-balloon catheter designed to simplify EUS-guided gastroenterostomy for gastric outlet obstruction. It outlines key procedural steps: guidewire placement into the proximal jejunum, advancing and inflating the dual balloons, exchanging the scope while preventing deflation, injecting diluted contrast for bowel distention, and deploying the lumen-apposing metal stent under EUS/fluoroscopy guidance. Practical tips address difficult wire passage, balloon leaks, repositioning for better sonographic windows, and complete balloon deflation before removal. In a 12-patient series, technical success was 91.7%, clinical success 100%, and adverse events were uncommon.
