Standardisation of polypectomy technique

There are several approaches to polypectomy for sessile polyps <20 mm and for pedunculated polyps. Recent evidence is leading towards standardisation of polypectomy technique. Key recent polypectomy developments include: 1. Use of cold snare polypectomy (CSP) for sessile polyps <10 mm; 2. Use of hot snare polypectomy (HSP) following submucosal injection for sessile polyps sized 10-19 mm; 3. Piecemeal cold snare polypectomy (PCSP), with or without prior submucosal injection, for select sessile polyps sized 10-19 mm, where the potential risk for an adverse event is increased (e.g. polyps in the caecum or ascending colon, or patients with increased risk of post-polypectomy bleeding), and where the risk of submucosal invasion is low; 4. Avoidance of hot biopsy forceps (HBF); 5. Limiting the use of cold biopsy forceps (CBF) to the smallest of diminutive polyps, where CSP is not feasible; 6. Mechanical haemostasis prior to polypectomy for large pedunculated polyps with head ≥20 mm or stalk ≥10 mm.
