Input (English): Question: Do cold snare piecemeal resection of colonic and duodenal polyps ≥1 cm?
Answer: Cold snare polypectomy for large duodenal and colonic polyps is technically feasible and may have a favorable safety profile compared to standard electrocautery-based endoscopic resection. Comparative trials are required to determine the relative safety and efficacy of cold snare techniques for complete and durable resection of large polyps compared to standard hot snare methods.
Output (English): yes
