Pcf h290

Colon pretreatment was performed using 0.15-L magnesium citrate on the night before the ESD and using 1.2 to 2-L low-volume polyethylene glycol solution (Moviprep, EA Pharma Co. Tokyo, Japan) on the day of ESD. When the stool became clear, colon preparation was considered complete. If the stools were not clear after taking 2 L of low-volume polyethylene glycol solution, 120-mL glycerine enema or isotonic magnesium citrate solution was used.
ESD was performed using a colonoscope with a waterjet instrument (PCF-H290, CF-HQ290 or PCF-H290T; Olympus, Tokyo, Japan) and an attachment (D-201-12704; Olympus) fitted to the tip. Incision and dissection were performed with a FlushKnife BTS (DK2620 J -B15S-; Fujifilm) or a DualKnifeJ (KD-655Q; Olympus, Tokyo, Japan). Precut-coagulation of vessel or hemostasis was performed with Coagrasper (FD-411QR; Olympus, Tokyo, Japan). In addition, hyaluronic acid (MucoUp; Boston scientific Tokyo, Japan) with a small volume of epinephrine and indigo carmine was injected.
High-frequency power supply (VIO300D; Erbe, Tübingen, Germany) was used. The endocut I mode (effect 3, duration 2, interval 2) was used for mucosal incision and submucosal dissection. The forced coagulation mode 45 W (effect 2) was used for submucosal dissection, and the soft coagulation mode 80 W (effect 5) was used for precut-coagulation and hemostatic treatment.
