The details of the proposed study are as follows:~Experimental group: using EverLift submucosal injection for polyps 4-9mm of the colon~Control group: not using EverLift submucosal injection for polyps 4-9mm of the colon~Methods:~Colonoscopy will be performed in the same standard of care manner as if no study was taking place.~If polyps 4-9mm are identified, the endoscopist is randomized to performing polypectomy with or without submucosal injection of EverLift.~After removal of the polypectomy, two biopsies are performed at the margin of the polypectomy site to identify residual lesion.~The polyp as well as well as the two biopsies are reviewed by a pathologist.
The focus of the study is to evaluate impact of submucosal injection of EverLift in achieving complete resection during polypectomy of polyps 4-9mm during colonoscopy.
