ASGE Annual Postgraduate Course: Clinical Challenges and Real-Time Decision Making in GI Endoscopy (On-demand) | 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

The video features Dr. Douglas Wodomura who discusses various classifications used in the optical diagnosis of colonic polyps. He first talks about the Paris classification, which categorizes polyps based on their appearance. He then introduces the LST classification, which further categorizes laterally spreading tumors. Dr. Wodomura explains that these classifications help predict the pathology and difficulty of polyp removal.<br /><br />He then moves on to discuss the PIT pattern classification, which uses indigo carmine or crystal violet to highlight the pits in the mucosal surface. Each subtype of PIT pattern corresponds to different histological findings. The NICE classification is also introduced, which simplifies the NBI classifications and categorizes polyps as hyperplastic/serrated, adenoma, or cancer. The JNET classification is briefly mentioned, which further stratifies type 2 polyps into type 2A and type 2B.<br /><br />Dr. Wodomura concludes by discussing the limitations of the NICE and JNET classifications and suggests using them alongside other classifications like Paris for a comprehensive understanding of polyps.<br /><br />In addition, the panelists in the video discuss the optical diagnosis of colonic polyps. They emphasize the importance of macroscopic and microscopic assessment, as well as techniques like chromoendoscopy and comparing endoscopic and pathological findings. They address specific challenges, such as distinguishing between Sessile Serrated Lesions (SSLs) and adenomas, and provide recommendations for management based on risk stratification.<br /><br />Overall, the video provides valuable insights and recommendations for clinicians to enhance their skills in the optical diagnosis of colonic polyps.
