ASGE Annual Postgraduate Course: Clinical Challenges and Real-Time Decision Making in GI Endoscopy (Live and Virtual) | May 2023-ASGE ENDO Hangout for GI Fellows - Optical Diagnosis of Colon Polyps and Magnifying Endoscopy

ASGE ENDO Hangout for GI Fellows - Optical Diagnosis of Colon Polyps and Magnifying Endoscopy | August 2022

Video Transcription

Video Summary

This video is a presentation on the optical diagnosis of colon polyps and magnifying endoscopy. It covers the Paris classification, which describes polyps based on their appearance, and the LST classification, which further categorizes flat polyps. The risk of submucosal carcinoma associated with each type of polyp is explained. The NICE classification, which uses Narrowband Imaging to classify polyps visually, is introduced, as well as the JNET classification, which stratifies type 2 polyps. The presenter provides examples and demonstrates how to identify each type of polyp using NBI. The limitations of the NICE classification and the usefulness of pit pattern diagnosis with crystal violet are discussed. The video concludes with a panel discussion on reporting polyps using both the Paris and NICE classifications. The presentation was provided by panelists and moderators who provided a comprehensive overview of colonic polyps and their optical evaluation. The need for a systematic approach to accurately diagnose and effectively manage polyps was emphasized, along with the potential benefits of chromoendoscopy with indigo carmine in delineating polyp characteristics. The presentation also touched upon the diagnosis of serrated polyposis syndrome and the management of sessile serrated lesions. Overall, the session provided valuable insights into the optical assessment of colonic polyps.
