Colorectal polyps from 10 mm to 25 mm was found. Submucosal injection of saline solution before removal was not performed for polypectomy. The snare used for polypectomy was a dual loop wire snare with a loop size of 33/16 mm (SN-3316LX, Medico's Hirata Inc., Osaka, Japan). An ERBE ICC200 (Amco, Tokyo, Japan) was used in the Endocut mode with the effect 3 current set at output limit 120W and forced coagulation current set at output limit 35W for conventional polypectomy. Prophylactic clipping after polyp removal was routinely performed.

Colorectal polyp from 10 mm to 25 mm was found. Submucosal injection of saline solution before removal was performed for EMR.
