Lesion Characterization | May 2025-Recorded Webinar

Video Transcription

Video Summary

The webinar organized by the American Society for Gastrointestinal Endoscopy focused on the crucial topic of lesion characterization. The session featured distinguished panelists, including Professor Yahagi from Japan and Professor Altman from the USA, who provided insights into the assessment and treatment of gastrointestinal lesions. <br /><br />Professor Yahagi emphasized the importance of thorough inspection and cleaning of the gastrointestinal lumen to identify suspicious lesions accurately. He highlighted the significance of using narrowband imaging (NBI) and chromoendoscopy to characterize lesions and determine their extent, particularly for early gastric cancer and duodenal lesions. Yahagi discussed the role of magnifying endoscopy and emphasized the special considerations for signetring carcinoma given its aggressive nature. <br /><br />Professor Altman provided insights into the NICE and JNET classifications for assessing colorectal lesions, emphasizing the importance of distinguishing between granular and non-granular lateral spreading tumors. He discussed the considerations for opting between endoscopic resection techniques, such as endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD), highlighting the criteria that guide this decision, including lesion morphology and potential submucosal invasion.<br /><br />The session delved into the challenges and strategies involved in lesion characterization, with experts stressing the need for continuous learning and training for endoscopists. Key advice from the panelists included the utilization of enhanced imaging techniques, maintaining updated knowledge on classification systems, and fostering a culture of thorough lesion assessment in clinical practice, especially among trainees. <br /><br />The panel concluded with a call for further educational efforts and collaboration among gastroenterologists to advance skills in lesion characterization, aiming to improve diagnostic accuracy and patient outcomes in gastrointestinal endoscopy.
