Efficacy and Safety of Precut-EMR for Resecting of Colonic Polyp

"For treating of 10\~20mm colon polyp, patient will be randomly divided into two groups, a Precut-EMR group and a EMR group.~In Precut-EMR, endoscopist submucosally inject with saline around a polyp. Subsequently, circumferential incision/precutting was made with the tip of the snare around 2 mm outside the tumor. After that, the snare was positioned in the cut groove and tightend, and the tumor was resected using electrical current."

EMR had been widely used technique. Endoscopist submucosally inject with saline around a polyp. After that, snare is positioned around a polyp, and polyp was resected using electrical current.
