932 polyps retrieved when trap is attached to instrument port are more frequently intact and interpretable than when removed by conventional method

A major limitation of determination of the completeness of resection in colonoscopy polypectomy is polyp fragmentation. When a polyp fragments, the pathologist cannot determine resection completeness. In current practice, the polyp is retrieved following traversing the entirety of the colonoscope and the specimen negotiates lumen diameter change at the suction valve. Alternative approaches to reduce polyp fragmentation include removal of the suction valve button or alternatively removing polyps through the instrument channel thereby bypassing issues of polyps traversing the suction valve passage entirely.
