Official Title: A Randomized Controlled Trial to Evaluate Effectiveness and Safety of the Endoscopic Removal of Large and Flat Colonic Polyps With LumenR RetractorTM (LR) as a Modified Colonic Overtube

Brief Summary:

Colorectal cancer accounted for 142,570 new cancer cases and 51,370 cancer deaths in USA in 2010 and worldwide has become the third most common cancer and second leading cause of cancer related deaths. Colonic adenomatous polyps are known precursors of colorectal cancer and endoscopic removal of the polyps prevents development of colon cancer.

Removal of such large polyps requires special endoscopic techniques-endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD), which are more technically difficult to perform, labor intensive, time consuming and carries higher risks of complications (bleeding, perforations, etc.). The purpose of this study is to determine the effectiveness and safety of the LumenR Retractor in performing EMR and ESD. It is hypothesized that the use of this modified colonic overtube will simplify colonoscopic removal of difficult polyps, decrease the time needed to complete the procedure and decrease the rate of complications post endoscopic removal of large and flat colonic.
