Proficiency in Cold Snare Polypectomy: Fellow Milestones

Key Takeaways

  • Clinical Bottom Line
  • The Eradication of "Cold Biopsy" Remnants

Clinical Bottom Line

Polypectomy Technique Electrosurgical Input Fellow Competency Marker
Cold Forceps Avulsion None. Very high rate of incomplete resection. Should be universally abandoned for anything larger than 2mm.
Cold Snare Polypectomy (CSP) None. Purely relies on the mechanical guillotine force of a thin stiff wire. Standard of care for all ademonas 3mm to 9mm; perfect safety profile.
Hot Snare Polypectomy (HSP) Blended microprocessor current (EndoCut). Reserved exclusively for large lesions (>10mm) or thick-stalked pedunculated polyps.

The Eradication of “Cold Biopsy” Remnants

Historically, endoscopists frequently utilized simple biopsy forceps to “bite” off small 5mm polyps. This practice resulted in alarmingly high incomplete resection rates (often >30%), leaving behind microscopic rings of adenomatous tissue that silently evolved into interval colon cancers before the patient’s next scheduled colonoscopy.

The Shift to Universal Guillotining

The standard baseline competency for a graduating gastroenterology fellow in 2026 is the rapid, flawless execution of the Cold Snare Polypectomy (CSP) for all diminutive and small polyps (<10mm). CSP utilizes a dedicated, thin-wire stiff snare. The snare is aggressively compressed entirely flat against the mucosa, capturing 1-2mm of completely normal surrounding tissue alongside the polyp. Because no heat is utilized, the risk of delayed post-polypectomy mural burns or thermal perforation drops to zero, and the snare provides an almost perfectly clean, macroscopic resection margin.
