Colorectal endoscopic submucosal dissection (ESD) is spreading in the world, but there are still several problems such as poor manipulation, breathing movement, severe fibrosis, and long procedure time. Pocket-creation method (PCM) is a method that makes a submucosal pocket below a tumor, so that the endoscope becomes stable in the pocket. This method is useful for a lesion with severe fibrosis or poor manipulation. However, making a pocket is sometimes challenging, especially for non-experts. On the other hand, S-O clip (Zeon Medical Co., Tokyo, Japan) is a traction device, and it allows us to pull a lesion upward and makes ESD procedure time shorter. However, cases with breathing movement and poor manipulation are still difficult when we use S-O clip. We herein presented a case of colorectal ESD using the combination of PCM and S-O clip for improving each difficulty. Sufficient traction with S-O clip allows an easy formation of a submucosal pocket, and PCM enables us to achieve stable endoscopic view even in cases with S-O clip.

PCM and S-O clip are useful and spreading; however, each method has difficulties. Regularly, these 2 methods are each used independently. However, we developed a combination of PCM and S-O clip. First, circumferential mucosal incision is performed followed by deploying S-O clip. Then, only the center of submucosa is dissected to make a pocket, and a stable view can be achieved. It allows us to resolve each difficulty and make ESD fast and standardized. Additionally, Clutchcutter (Fujifilm, Tokyo, Japan), which is a scissor-type knife, makes ESD safer and easier compared to needle-type knives.

Using this combination method with Clutchcutter, endoscopists can perform stable and safe colorectal ESD even if they don’t have enough experience with gastric ESD. So far, S-O clip had not been released in Western countries. There are several other traction devices like S-O clip; we suggest this combination method can be performed with these other devices.
