Masterclass: EndoQuest - Endoscopy in the GI Unit (On-demand) | September 2025-Barrett’s Esophagus Unveiled: Tools, Techniques, and Care Explained

Video Transcription

Video Summary

Dr. Patricia Davila presented a comprehensive overview of Barrett's esophagus, a precancerous condition caused by intestinal metaplasia of the esophagus, primarily due to chronic gastroesophageal reflux. Barrett's can progress to esophageal adenocarcinoma through dysplasia stages, with males and Caucasians at higher risk. The importance of thorough endoscopic evaluation was emphasized, involving high-definition white light endoscopy and electronic chromoendoscopy (e.g., narrowband imaging) to enhance visualization of lesions. A meticulous biopsy strategy, following the Seattle protocol (four-quadrant biopsies every 1-2 cm), is essential to detect dysplasia or cancer, focusing on nodules first.<br /><br />Dr. Davila detailed radiofrequency ablation (RFA) as a key treatment, especially for Barrett's with low-grade or high-grade dysplasia. The RFA system includes a generator, catheters (balloon and focal devices), and a pedal for activation. The balloon catheter suits long, circumferential Barrett’s segments, and focal catheters target short or patchy areas. The procedure involves delivering thermal energy to ablate diseased mucosa in staged sessions spaced 2-3 months apart to allow healing. Post-procedure care includes pain management and dietary modifications.<br /><br />She underscored the collaborative role of endoscopy technicians and nurses, proper specimen labeling, and patient monitoring to ensure high-quality care and successful Barrett's esophagus management.
