Overview
OBJECTIVES The aim of the study is to compare the efficacy of cold snare EMR versus hot snare EMR for non-pedunculated polyps 10-20mm in size with respect to complete resection rates and adverse events.
DESIGN : A Randomised interventional study. Sample size: 330
Description
- This procedure will be performed by Endoscopists having above 3 years of experience you
will be in the left lateral position under propofol sedation.
- In Both groups (a mixture of saline and blue dye will be injected beneath the surface layer,and then a snare(is a ring shaped device used to cut polyp after surrounding itlike a rubber band ) will be used to remove tissue without using heat in Cold Endoscopic mucosal resection group and using electrosurgical unit (to control bleeding and to rapidly dissect soft tissue in surgery) by EndoCut Q mode (ensures safe and effective removal of large lesions in particular large polyps) in Hot Endoscopic mucosal resection group.
- After polypectomy (the surgical removal of a polyp) the area is inspected for residual polyp (presence of any type of tissue) using NBI (Narrow band imaging) and if present, will be CUT OFF.
- A Standard snare ( snare is a ring shaped device used to cut polyp after surrounding it- like a rubber band) is used to cut the polyps
