Circumferential Submucosal Incision Endoscopic Mucosal Resection Versus Conventional Endoscopic Mucosal Resection of Colonic Polyps (CSIEMR)

March 25, 2025 updated by: Professor Michael Bourke

Circumferential Submucosal Incision Endoscopic Mucosal Resection Versus Conventional Endoscopic Resection for the Removal of Large Laterally Spreading Tumours and Sessile Polyps of the Colon

That Circumferential Submucosal Incision Endoscopic Mucosal Resection (CSI-EMR) will be at least as safe but more effective than conventional EMR for injection assisted EMR of large laterally spreading tumour and sessile polyps of the colon.

Detailed Description

The investigators have recently developed a new, and the investigators believe safer and more effective technique for endoscopic mucosal resection (EMR). Utilising the new method the investigators make small cuts around the polyp to isolate it. Subsequently the Gelofusine solution is injected beneath the polyp and provides greater elevation. This allows us to improve the chance of removal of the entire polyp with one attempt in one piece. It is preferable to remove the polyp in one piece as it minimises the chance of leaving residual polyp tissue behind. Our team has recently completed an animal study comparing our newly developed technique to conventional EMR. The investigators have found significant improvements in our ability to completely remove the polyp in one attempt. There have also been recent studies overseas that have shown this new technique to be quite effective.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Circumferential Submucosal Incision Resection
Procedure: Circumferential Submucosal Incision Resection
The patient is randomized, if in the active arm the procedure will continue as Circumferential Submucosal Incision Endoscopic Mucosal Resection.
Active Comparator: Endoscopic Mucosal Resection
Patients randomised into this arm will receive the conventional treatment Endoscopic Mucosal Resection in which the sessile lesion is injected and snared by piecemeal technique.
Procedure: Endoscopic Mucosal Resection
Patients randomised into this Intervention type will have Endoscopic Mucosal Resection performed
