 CSP(cold snare polypectomy)has been reported to minimize the risk of complications, and it has become a standard treatment for small colorectal polyps. We considered that CSP might also be suitable for small duodenal polyps.

 CSP was performed using an electrosurgical snare without electrocautery. The polyp, including the normal surrounding mucosa, was snared to maintain a non-neoplastic mucosal margin around the lesion. Blood was oozing immediately after CSP but stopped soon without requiring any endoscopic hemostasis.

 This technique appeared to be safe, with the following three advantages:①It did not require electrocautery ; therefore, there was no possibility of delayed perforation due to the thermal burn effect. ②The depth of the layer cut by CSP was shallower than that cut by ESD. ③The mucosal defect following CSP was smaller than that following ESD, making its closure easy using standard endoclips.
