Study Arms (2)

Cold snare polypectomy

ACTIVE COMPARATOR

Cold snare resection, if necessary, multi-piece to resect sessile serrated adenoma (SSA) 8-20mm

Procedure: Cold snare polypectomy

Endoscopic mucosal resection

ACTIVE COMPARATOR

Endoscopic mucosal resection (EMR), if necessary, multi-piece to resect sessile serrated adenoma (SSA) 8-20mm

Procedure: Endoscopic mucosal resection

Interventions

Use of a polypectomy snare closed over a polyp without electrocautery

Also known as: CSP
Cold snare polypectomy

Use of injected chromogelofusine solution to raise a lesion prior to snare resection with electrocautery

Also known as: EMR
Endoscopic mucosal resection
