Tu1001 Removal of Suction Trap Valve Leads to Reduction in the Extent to Which Colorectal Polyps Are Fragmented Upon Retrieval

Incomplete resection of adenomatous polyps removed by snare resection is an emerging issue relevant to interval colorectal cancer. A previous study (CARE trial) showed an incomplete resection rate in up to 23% of some colonoscopists’ polypectomy specimens. A major limitation of determination of completeness of resection pathologically is polyp fragmentation. Once a polyp is fragmented into multiple pieces resection adequacy cannot be determined...
