Use of a Dual knife has become commonplace for endoscopic submucosal dissection (ESD) of colorectal tumors at Hiroshima University Hosipital. A Hook knife has been also used in combination with the Dual knife, depending on the location of the lesion. We have had recent opportunities to use a scissors-type SB knife Jr. We retrospectively compared outcomes of colorectal ESD performed with the Dual knife in combination with the SB knife Jr versus the Hook knife. In conclusion, although the Hook knife was shown to be a very useful auxiliary device for colorectal ESD, the SB knife Jr. yielded better results than the Hook knife in terms of complete en block resection and avoidance of perforation. Use of the Dual knife with the SB Knife Jr shows good potential for improving complete en bloc resection rate and safety of technically difficult colorectal ESD.
在广岛大学医院，双极刀已成为结直肠肿瘤内镜黏膜下剥离术（ESD）的常规手段。根据病变部位的不同，我们还结合使用钩刀。最近，我们有机会使用 SB 刀 Jr 型的剪刀式。我们回顾性比较了双极刀联合 SB 刀 Jr 与钩刀行结直肠 ESD 的结果。总之，虽然钩刀在结直肠 ESD 中是一种非常有用的辅助设备，但在整块切除率和避免穿孔方面，SB 刀 Jr 优于钩刀。双极刀联合 SB 刀 Jr 的使用显示出提高技术难度较大的结直肠 ESD 整块切除率和安全性的良好潜力。
