Endoscopic submucosal dissection (ESD) is a standard treatment for colorectal neoplasms, but the risk of severe postoperative complications persists even after successful ESD [1, 2]. Therefore, complete closure of defects after ESD is essential to prevent such complications [3]. Although complete closure is a technically difficult procedure, several techniques have been developed to assist [4, 5]. Herein, we present a case of successful complete closure of a mucosal defect after colonic ESD using clips with a silicone traction band (▶Fig. 1). ESD was performed to resect a 35-mm laterally spreading tumor located in the ascending colon; however, a 50-mm mucosal defect remained after lesion retrieval. Pulsating vessels and minor muscular injuries were observed in this defect. Endoscopic closure using clips with a silicone traction band was performed on the lesion (▶Video 1). The first clip with a band was placed at the proximal edge of the mucosal defect (▶Fig. 2 a). The second clip was placed at E-Videos
