Polypectomy: Which Snare for Which Polyp?

Snare selection is treated as a clinical decision, not a catalog browse. The lecture classifies snares by wire (braided vs monofilament), shape (oval, hexagonal, asymmetric, and related profiles), size/length, and catheter diameter so they still suction through 2.8 to 3.2 mm channels. Technique is shown as a dynamic process: inspect surface and location, decide on lift for margin/safety, park the catheter nearly flush, open the snare off the lesion, then torque/wheel the scope so the lesion sits centered before closing. Cold snare examples sit beside hot work, and EMR history is used to justify saline cushions when folds hide depth (less deep injury, better lateral/vertical margin). Assistants are part of the system: coordinated handle closure while the endoscopist advances and positions. Takeaways are which snare traits fit which polyps, plus reproducible positioning and cushion habits.
