Core Tip

Core Tip: Complete polyp resection is the main goal of endoscopic removal of large colonic polyps. Resection techniques have evolved in recent years and endoscopic submucosal dissection, endoscopic mucosal resection (EMR) with margin ablation, cold snare polypectomy, cold EMR, and underwater EMR have been introduced. Yet, efficacy of these techniques with regard to local recurrence rates (LRRs) vs traditional hot snare polypectomy and standard EMR remains unclear. We aimed to analyze LRR of large colonic polyps in a systematic review and meta- analysis.
