Size Cut-Off for Removal of Pedunculated Polyps

Pedunculated Polyp Management Based on Size

Hot snare polypectomy (HSP) should be used to remove pedunculated polyps >10 mm in size, while cold snare polypectomy (CSP) can be considered for pedunculated polyps <10 mm with thin stalks 1, 2, 3
Cold snare polypectomy (CSP) can be safely used for small pedunculated polyps (<10 mm) with thin stalks 1, 3
Hot snare polypectomy (HSP) is recommended for pedunculated polyps >10 mm to decrease the risk of immediate bleeding 1, 2, 4
Pedunculated polyps contain a feeding blood vessel within the stalk, making thermal therapy important for larger lesions 1
Polyps should be transected low enough on the stalk to allow appropriate resection margin and pathologic evaluation 1

Polyp size ≥10 mm is a known risk factor for bleeding 1, 2
Stalk diameter ≥5 mm significantly increases bleeding risk 1, 4
Prophylactic measures are recommended for high-risk pedunculated polyps, particularly those with heads ≥20 mm 1, 4 or stalks ≥5 mm 1, 2

For pedunculated polyps with heads ≥20 mm and/or stalks ≥5 mm, consider epinephrine injection into the stalk 1
For pedunculated polyps with heads ≥20 mm and/or stalks ≥5 mm, consider prophylactic placement of detachable nylon loops (Endoloop) 1
For pedunculated polyps with heads ≥20 mm and/or stalks ≥5 mm, consider standard clips 1, 4

Prophylactic clipping is generally not recommended for polyps <20 mm regardless of location or patient anticoagulation status 1, 4
Referral to specialized endoscopic centers should be considered for polyps ≥20 mm or those in challenging locations 5

For pedunculated polyps with suspected or confirmed malignancy, ensure complete resection with negative margins (at least 2 mm) 1, 6
Pedunculated malignant polyps are considered high risk if they have: poor differentiation, lymphovascular invasion, submucosal invasion >1 mm, cautery margin, or tumor budding 6
