Post-resection Treatment of Large Colon Polyps

Data regarding polyp morphology, location \& shape will be recorded in addition to procedure and treatment length. Injection fluid use and clipping will also be recorded in addition to any procedural complications. All randomized subjects will receive a 30-day post procedure follow-up phone call and be scheduled, as per the standard of care, to receive a standard follow-up colonoscopy procedure after the initial procedure. The investigators will measure the rate of recurrence by endoscopic visualization of the EMR site at the first follow-up using endoscopic magnification and electronic chromoendoscopy, as well as systematic biopsy of the scars.
