Endoscopic submucosal dissection of a rectal nongranular laterally spreading tumor with the use of a new endoscopic?platform

摘要

Endoscopic submucosal dissection (ESD) is a technicallydemanding and time-consuming procedure. The main challenges are related to the instability of the operating fieldand to the lack of traction, owing to the single operatingchannel.1The ORISE Tissue Retractor System ([TRS]Boston Scientific, Marlborough, Mass, USA) is a newendoscopic platform that consists of an expandable anddynamically controlled intraluminal chamber, mounted on aflexible overtube, with 2 specifically designed retractorgraspers.
