Since 1982, the medical literature as well as the lay press discussed an artificial bezoar, the gastric bubble, as an adjuvant in the treatment of morbid obesity. Approved by the FDA, the Garren-Edwards Gastric Bubble has been reported by the company to have been placed over 17,000 times. Due to a reported increased rate of deflation after three months, removal and reimplantation of a new bubble is recommended. After deflation, some difficulty in retrieval of the bubble has been reported. The authors report a new technique for bubble extraction. The bubble is visualized through a gastroscope and deflated using bicap cautery. The gastroscope is removed. The endo-overtube is placed on the gastroscope and this assembly is reintroduced through the esophagus to the level of the GE junction. The deflated bubble is visualized, grasped with a forceps, and withdrawn into the endo-overtube until becoming wedged. The entire assembly (gastroscope, overtube, forceps, and gastric bubble) are removed. With this technique, bubble removal has been simplified and has decreased the procedure length to approximately fifteen minutes.
自1982年以来，医学文献以及大众媒体都讨论过一种人造牛黄——胃泡，它作为病态肥胖治疗的辅助手段。经美国食品药品监督管理局（FDA）批准，加伦-爱德华兹胃泡已被该公司报道植入超过17000次。由于据报道三个月后胃泡放气率增加，建议取出并重新植入一个新的胃泡。放气后，有报道称胃泡取出存在一些困难。作者报告了一种新的胃泡取出技术。通过胃镜观察胃泡，并用双极电凝使其放气。取出胃镜。将内镜外套管置于胃镜上，然后将这个组件通过食管重新插入至胃食管交界处水平。观察到放气后的胃泡，用钳子抓住，将其拉进内镜外套管直至卡住。取出整个组件（胃镜、外套管、钳子和胃泡）。采用这种技术，胃泡取出过程得到简化，手术时间缩短至约15分钟。
