Masterclass: Advanced GI Endoscopic Imaging (Live/Virtual) | December 2025-Resection Decisions Based on Lesion Characteristics

Video Transcription

Video Summary

Dr. Robert delivered a detailed lecture on resection decisions for colorectal lesions based on lesion characteristics and quality colonoscopy indicators. Key updates include raising adenoma detection rates (ADR) benchmarks from 25% to 35%, emphasizing an 8-minute withdrawal time, and adding metrics for sessile serrated lesions and fecal positive screenings. He reviewed macroscopic and microscopic lesion classifications, highlighting the usefulness of the Laterally Spreading Tumor (LST) and NICE/JNET classifications for assessing cancer risk. The lecture illustrated how meticulous lesion examination using enhanced imaging and magnification guides management decisions, demonstrating through case studies how features like depressed areas, vascular and surface irregularities correlate with pathology, such as high-grade dysplasia or invasive carcinoma. The importance of systematic assessment including Paris classification, pit patterns, and identifying high-risk signs like chicken skin mucosa or spontaneous bleeding was emphasized to optimize resection strategies and improve colorectal cancer outcomes.
