Endoscopic submucosal dissection using a novel vibration endoscopy.
OBJECTIVE
Endoscopic submucosal dissection (ESD) technique requires special skill and involves a prolonged procedure time. Therefore, the present study aim is to increase the efficiency of endoscopic treatment techniques by vibrating the endoscope scope itself. The usefulness of this vibration endoscopy for ESD was evaluated in 6 porcine stomachs.


METHODS
Vibration endoscope modified a commercial endoscope (Olympus: GIF-Q200). Investigations to measure procedure time were conducted separately with and without vibration of 5,000 or 10,000 rpm applied at the time of circumferential incision and submucosal dissection.


RESULTS
Among circumferential incisions, submucosal dissection and a total of both, the average procedure durations with vibration at 10,000 rpm were significantly shorter than that without vibration.


CONCLUSIONS
When performing peripheral incisions and submucosal dissection with a knife in ESD, the time for the procedure was reduced by adding vibration.
