Interventional
Description of intervention(s) / exposure
Treatment: Surgery - Cold snare polypectomy
Treatment: Surgery - Endoscopic mucosal resection

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

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


Treatment: Surgery: Cold snare polypectomy
Use of a polypectomy snare closed over a polyp without electrocautery

Treatment: Surgery: Endoscopic mucosal resection
