Mo1718 THE POCKET-CREATION METHOD FACILITATES ENDOSCOPIC SUBMUCOSAL DISSECTION OF COLON TUMORS

Pay attention to a “window-blind” appearance of the distal rectal muscle layer during endoscopic submucosal dissection

“…The PCM does not need air insufflation to maintain the endoscopic visual field because the transparent hood with small-caliber tip easily maintains the visual field. Refraining from air inflation can make the submucosa thick and the rectal wall tangential (▶ Video 1) [2]. The PCM therefore allows us to easily dissect the distal rectal submucosa without a reversal procedure.…”
