Clinical Bottom Line
| Polypectomy Category | Instruments Utilized | Optimal Target Lesion |
|---|---|---|
| Cold Snare Polypectomy (CSP) | Stiff, thin-wire dedicated cold snares. | Diminutive (<5mm) and small (6-9mm) adenomas. |
| Endoscopic Mucosal Resection (EMR) | Injection catheters, stiff hot snares, prophylactic TTS clips. | Large (≥10mm) or flat sessile polyps (LSTs). |
| Endoscopic Submucosal Dissection (ESD) | Electrosurgical knives (DualKnife, ITKnife), distal caps. | Suspected superficial invasive carcinomas requiring en bloc resection. |
The Shift in Polypectomy Paradigms
The instrumentation required for effective polyp removal has stratified heavily based on lesion morphology and size. In 2026, the global consensus mandates that practically all benign polyps under 10mm should be removed en bloc utilizing cold snare technique. This relies on specialized cold snares engineered with stiff, ultra-thin wire that guillotine tissue cleanly without the need for submucosal injection or electrocautery.
Advanced Resection (EMR and ESD)
For larger laterally spreading tumors (LSTs), endoscopists must deploy advanced toolkits. Endoscopic Mucosal Resection requires highly reliable injection needles using viscous lifting agents (e.g., Eleview, Orise) followed by stiff hot snares. Conversely, ESD relies on highly technical electrosurgical knives and cap-assisted maneuvering to methodically dissect the submucosal plane, enabling complete curative resection of challenging lesions previously referred to surgery.
