EndoscoPic Submucosal dIssection Using geL Versus glycerOl for Submucosal iNjection

Overview

The EPSILON study aims to comparatively evaluate the submucosal injection using ORISETM gel and glycerol during an ESD procedure in a specific population with superficial gastric and rectal (pre)neoplastic lesions.

Traditionally, ESD requires the injection of some colloidal solution (glycerol, geloplasma, hydroxyethylstrach, etc.) in the submucosal layer in order to obtain long lifting effect and thus allowing the endoscopist to dissect under the lesion. Alternatives to colloid-solution assisted ESD have also been developped: pocket creation method and saline-immersion ESD. Recently, other colloidal solutions have arrived on the market, such as gel (ORISETM gel) in order to improve the lifting during ESD.Our preliminary experience using ORISETM gel as a lifting solution for ESD was unexpectedly favourable with few per-procedural bleeding, quick time and facility. As the spread of ESD is closely associated to its easiness, procedure duration (itself associated to number of procedural bleedings and instruments change through the operating channel) and safety, we sought to study comparatively two submucosal solutions when conducting ESD in a specific population presenting gastric or rectal superficial lesions.
