Multicenter evaluation of recurrence in endoscopic submucosal dissection and endoscopic mucosal resection in the colon: A Western perspective

Figure 1 Endoscopic submucosal dissection. A and B: Steps of endoscopic submucosal dissection includes careful surveillance of the polyp, with techniques including near focus and narrow band imaging; C: Mucosal incision is performed following by submucosal dissection, which is aided by a submucosal lifting agent (in this case a mixture of epinephrine, hetastarch, and indigo carmine); D-F: Following complete resection of the polyp, the complete resection bed is closed, with techniques including clips.
