EndoscoPic Submucosal dIssection Using geL Versus glycerOl for Submucosal iNjection: a Randomized Controlled Multicentric Trial (EPSILON)

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.

Study Overview

Detailed Description

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.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Increase the dissection speed of the ESD procedure
Time Frame: At day 0 during ESD
Increase the dissection speed of the ESD procedure (defined as the dissected surface (mm2)/ESD duration (min). The dissected surface is defined as maximal diameter of specimen (mm) x perpendicular minimal diameter of specimen (mm) measured on ex-vivo pinned stretched specimen onto a cork. ESD duration is defined as the time from first submucosal injection to final cut time.

Clear visualisation of the plane of dissection during ESD (scale).
Time Frame: At day 0 during ESD

Clear visualisation of the plane of dissection during ESD (scale). The scale will be defined according the endoscopists evaluation of the delineation between the submucosa ad the underlying muscular layer:

  • Very-good visualization: clear delineation between the two layers with clear visualization of the blood vessels.
  • Good visualization: mostly clear delineation between the two layers, but with blurred regions
  • Bad visualization: delineation between the two layers is unclear (i.e.:

fibrosis)
