RESUMO
Video 1A 35-mm laterally spreading tumor partially infiltrated the interior portion of the diverticular orifice in the ascending colon. Glycerol and hyaluronate solution were injected into the submucosa to maintain adequate mucosal elevation. Mucosal incision and submucosal dissection were performed using a DualKnife and insulation-tipped knife from the anal side; however, safe submucosal dissection was challenging with these knives because of severe fibrosis and abundant blood vessels in the diverticulum. Therefore, to improve the visibility of the submucosa, a scissor-type knife and a multiloop traction device was used to facilitate the submucosal dissection. Finally, en bloc resection was achieved in 117 minutes without adverse events. A part of the diverticular defect after endoscopic submucosal dissection was clipped to prevent delayed perforation.
