The past decade has seen several advances in small-bowel endoscopic technologies. Although the endoscopic literature is full of large case series, there are few published prospective randomized trials designed to compare any of the currently available techniques and devices for deep small-bowel endoscopy. In this edition of the American Journal of Gastroenterology, Dr May and colleagues present the results of a prospective, randomized trial comparing two techniques for performing "push-and-pull" enteroscopy: double balloon and single balloon. Although this study is not without limitations, it represents a step in the right direction toward answering several important questions that have surfaced, as techniques for deep small-bowel enteroscopy have become mainstream in endoscopic practice.
过去十年中，小肠内镜技术取得了多项进展。尽管内镜文献中充满了大量的病例系列，但很少有前瞻性随机试验发表，旨在比较目前可用于深部小肠内镜检查的任何技术和设备。在本期《美国胃肠病学杂志》中，May 博士及其同事报告了一项前瞻性、随机试验的结果，该试验比较了两种进行“推-拉”式推进式小肠镜检查的技术：双气囊和单气囊。尽管这项研究并非没有局限性，但它朝着回答几个重要问题迈出了正确的一步，因为深部小肠推进式内镜检查技术已成为内镜实践的主流。
