Case 1. Colorectal ESD of large tubullovillous adenoma lesion, located in caecum, size 41×36×8 mm.
Mucosal Pocket Creation with ITknife nano
✔ After conducting mucosal cutting and dissection with DualKnife J,
I switched to ITknife nano as the approach was perpendicular to muscularis propria.
✔ After trimming, submucosal pocket was created successfully with ITknife nano
Managing Large Fibrotic Lesion using Two Types of Knives
✔ After widening mucosal pocket with ITknife nano, circumferential incision was continued with DualKnife J.
✔ Dissection Edge of the lesion was effectively managed with ITknife nano.
✔ In the final stage of the dissection, the approach to oral side of lesion became challenging and the severe fibrosis made dissection difficult.
Nevertheless, resection was completed by opening pocket with ITknife nano.
Case 2. ESD for anal lesion extending anal canal
Application of “2 Knives Technique” for Challenging Lesion
✔ Approach into the submucosal layer was difficult and the procedure was challenging due to bleeding . The incision was carefully advanced with controlling bleeding using DualKnife J.
✔ Dissection in retroflex position was enabled with DualKnife J.
✔ Because the angulation turned to be quite difficult, it switched to ITknife nano, and resection was continued safely.
✔ Despite challenging characteristic of the lesion, the procedure was completed with tailored approach by switching DualKnife J and IT knife depending on the situation.
