Outcome Measures

Primary Outcomes (1)

  • Incomplete resection rate

    Resected polyp tissue is collected in a unique specimen jar. Tissue from the perimeter and base of the polyp resection site is collected in separate specimen jar. Histological examination by the pathologist is conducted. Incomplete resection rate = Number of polyps with residual polyp tissue present in biopsy of the perimeter and base of the polypectomy resection site / Total number of polyps This is calculated for polypectomies utilizing either jumbo capacity biopsy forceps or cold snare.

    One week after colonoscopy date (when pathology results are available)

Secondary Outcomes (2)

  • Rate of tissue retrieval

    1 day (At time of colonoscopy)

  • Rate of procedure-related complications

    1 day (At time of colonoscopy)

Study Arms (2)

Jumbo cold forceps polypectomy group

EXPERIMENTAL

Polypectomy conducted with jumbo cold forceps

Device: Jumbo cold forceps polypectomy

Cold snare polypectomy group

EXPERIMENTAL

Polypectomy conducted with cold snare

Device: Cold snare polypectomy

Interventions

The specific jumbo cold forceps used are the Olympus EndoJaw Biopsy Forceps (open jaw diameter 8.5 mm) and the Boston Scientific RJ4 Biopsy Forceps (open jaw diameter 8.8 mm).

Jumbo cold forceps polypectomy group

The specific cold snares used are the Boston Scientific Captiflex Extra Small Oval Flexible Snare (loop width 11 mm), the US Endoscopy Dsnare Dimunitive Polypectomy and Suction System (loop width 9 mm), or the Boston Scientific Sensation Short Throw Oval Flexible Snare (loop width of 13 mm, 27 mm, or 30 mm).

Cold snare polypectomy group
