Pedunculated colorectal polyps with heads ≤ 1 cm in diameter can be resected using cold snare polypectomy

Area of Science:

• Gastroenterology
• Endoscopic procedures
• Colorectal surgery

Background:

• Cold snare polypectomy (CSP) is generally not recommended for pedunculated colorectal polyps.
• Pedunculated colorectal polyps require effective and safe resection methods.

Purpose of the Study:

• To compare the adequacy of CSP versus hot snare polypectomy (HSP) for resecting pedunculated colorectal polyps with heads ≤ 1 cm.
• To evaluate the safety and efficiency of CSP for this polyp type.

Main Methods:

• Retrospective cohort study of outpatients undergoing resection of 6-10 mm pedunculated polyps.
• Comparison between CSP and HSP groups from 2014-2019.
• Primary outcome: delayed bleeding; Secondary outcomes: procedure time, resection rates, immediate bleeding, clip usage.

Main Results:

• Similar patient and polyp characteristics, and en bloc resection rates between CSP and HSP groups.
• CSP showed significantly lower mean procedure time and fewer clips used compared to HSP.
• CSP had significantly less delayed bleeding (0%) but more immediate bleeding than HSP.

Conclusions:

• Cold snare polypectomy (CSP) is a viable and advantageous option for resecting pedunculated colorectal polyps with heads ≤ 1 cm.
• CSP offers benefits in terms of procedure time and reduced delayed bleeding compared to HSP.
