Summary
Brief summary (as posted)
Colorectal cancer remains the third most common cause of death from cancer worldwide. Colonoscopy allows removal of adenomatous polyps is the best colorectal cancer screening, according to the adenoma-carcinoma sequence. Recent studies have reported approximately 30% of interval cancer may be incomplete polyp resection. Complete polyp resection may be particularly important when implementing new methods for surveillance colonoscopies. Cold snare polypectomy (CSP) is considered to be a safer procedure for removing subcentimeter lesions than conventional hot snare polypectomy (HSP). CSP removal of polyps sized ≤5 mm have recommended by the European Society of Gastrointestinal Endoscopy guideline as the preferred technique. Previous report said that the complete resection rate of CSP for adenomatous polyps 4-9 mm in size was comparable to that of HSP, and in the foreseeable future CSP can be one of the standard techniques for 4-9 mm colorectal polyps. However, data on complete resection of colorectal polyps 1.0-1.5 mm in size is sparse. Investigators are interested in comparison of the resection rate of cold snare polypectomy for large (10-15 mm) and small (5-9 mm) colorectal polyps using CSP.

- Cold snare polypectomy ; Polyp size will be measured using the tip of the snare catheter (2.5mm).Small (5-9 mm) colorectal polyps will be removed with a polypectomy snare. Following the resection, jet stream of water will be used to wash mucosal defect thoroughly. After endoscopist's attestation that polyp removal was complete by carefully observe the resection margins with near focus mode, biopsies were performed from two marginal sites located symmetrically on the left and right of the mucosal defects to confirm residual polyp tissue.

- Cold snare polypectomy; Polyp size will be measured using the tip of the snare catheter (2.5mm). Large (10-15 mm) colorectal polyps will be removed with a polypectomy snare. Following the resection, jet stream of water will be used to wash mucosal defect thoroughly. After endoscopist's attestation that polyp removal was complete by carefully observe the resection margins with near focus mode, 4 biopsies will be performed from all four quadrants of resection margins.
