A therapeutic endoscope has a catheter for endoscopic retrograde cholangiopancreatography attached to inject the gel independently, without using an accessory channel of the scope. b The endoscope and the tube are attached with adhesive tapes, and their tips are attached with a transparent hood. c By placing the tube tip on the opposite side to the accessory channel, air bubbles at the side of the tube that cannot be reached by the accessory channel are cleaned out by the pressure of the injected gel.

Endoscopic images of esophageal endoscopic submucosal dissection (ESD) using the gel immersion technique in dual red imaging mode. The gel supply makes the visual field clear during esophageal ESD. a Gel immersion can makes the lesion clearer and helps with the dissection. b It also makes the bleeding point (red arrow) clearly visible.
