Outcomes
Primary Outcome Measures
Efficacy of Two Devices used in EMR
To explore the efficacy of two devices used in EMR (iSnare® system versus Snaremaster) as measured by the "Sydney Resection Quotient" (SRQ). SRQ is defined as "lesion size in mm divided by the number of pieces to resect" .
Secondary Outcome Measures
Compare the Use of Two Injectates
To compare the use of two injectates (saline versus HPMC mixture) with respect to efficacy as measured by the aforementioned SRQ.

5. Study Description
Brief Summary
The investigators seek to compare two techniques of removing pre-cancerous lesions from the colon. The investigators also will compare two solutions used during the procedure to determine if either solution allows for an improved removal of the tumors.
Detailed Description
The primary aim of the study is to compare the efficacy, efficiency and safety of two types of snares used in Endoscopic Mucosal Resection (EMR), a combined needle and snare unit (ISnare, US Endoscopy) versus an oval braided snare with spiral wire (Snaremaster, Olympus). The secondary aim is to explore whether EMR efficacy and efficiency is depended upon the injection solution used, saline versus Gonak (a solution containing HPMC, saline, and epinephrine) for EMR.
