Endoscopic submucosal dissection (ESD) for superficial gastrointestinal neoplasms has become widespread. However, certain aspects of the procedure remain difficult to manage, such as intraoperative bleeding and perforation. There are two kinds of scissor‐type knife: the Clutch Cutter (Fujifilm Co., Tokyo, Japan) and the SB knife (Sumitomo Bakelite Co., Tokyo, Japan). These knives have different features from other types of ESD knives and enable the performance of all ESD procedures, including mucosal incision, submucosal dissection, and hemostasis. The standard approach with scissor‐type knives involves first grabbing the tissue and then incising or dissecting it. Theoretically, perforation as a result of unintentional movement should never happen with scissor‐type knives compared to needle‐ or blade‐type knives, which may induce perforation through unintentional movement. Moreover, the rates of severe bleeding and self‐completion of ESD with scissor‐type knives by non‐experts were reported to be significantly better than for other knives. Thus, scissor‐type knives can resolve these problems and help to further standardize ESD globally. In this review, we summarize reports on the efficacy of such scissor‐type knives for ESD of gastrointestinal tumors. We also present the pocket‐creation method and the application of traction devices, such as dental floss and S‐O clips (Zeon Medical Co., Tokyo, Japan) for improving the performance of ESD with a Clutch Cutter.

剪刀式内镜下消化道浅表肿瘤黏膜剥离术的疗效

用于浅表胃肠肿瘤的内窥镜黏膜下剥离术 (ESD) 已变得普遍。然而，手术的某些方面仍然难以管理，例如术中出血和穿孔。剪刀式刀具有两种：Clutch Cutter（Fujifilm Co., Tokyo, Japan）和SB 刀（Sumitomo Bakelite Co., Tokyo, Japan）。这些刀与其他类型的 ESD 刀具有不同的特性，可以执行所有 ESD 手术，包括粘膜切口、粘膜下剥离和止血。剪刀式刀具的标准方法包括首先抓住组织，然后切开或解剖它。从理论上讲，与针型或刀片型刀具相比，剪刀型刀具绝不会发生因无意移动而导致的穿孔，这可能会通过无意的移动导致穿孔。此外，据报道，非专家使用剪刀型刀严重出血和自行完成 ESD 的比率显着优于其他刀具。因此，剪刀式刀具可以解决这些问题，并有助于在全球范围内进一步规范 ESD。在这篇综述中，我们总结了关于这种剪刀式刀具对胃肠道肿瘤 ESD 的疗效的报告。我们还介绍了口袋创建方法和牵引装置的应用，例如牙线和 S-O 夹（Zeon Medical Co.，Tokyo，Japan），用于提高离合器切割器的 ESD 性能。剪刀式刀具可以解决这些问题，并有助于在全球范围内进一步规范 ESD。在这篇综述中，我们总结了关于这种剪刀式刀具对胃肠道肿瘤 ESD 的疗效的报告。我们还介绍了口袋创建方法和牵引装置的应用，例如牙线和 S-O 夹（Zeon Medical Co.，Tokyo，Japan），用于提高离合器切割器的 ESD 性能。剪刀式刀具可以解决这些问题，并有助于在全球范围内进一步规范 ESD。在这篇综述中，我们总结了关于这种剪刀式刀具对胃肠道肿瘤 ESD 的疗效的报告。我们还介绍了口袋创建方法和牵引装置的应用，例如牙线和 S-O 夹（Zeon Medical Co.，Tokyo，Japan），用于提高离合器切割器的 ESD 性能。
