EUS-ZENKER'S DIVERTICULUM ADVANCING BEYOND THE TUNNEL

Video Transcription

Video Summary

The video provides a summary of different endoscopic methods for treating Zenker's diverticulum and related conditions. It discusses the traditional endoscopic cricopharyngeal myotomy procedure, where a nasogastric tube is inserted to outline the esophageal lumen. A myotomy of the cricopharyngeal muscle is performed along with septotomy to achieve complete myotomy. However, incomplete myotomy can lead to high relapse rates. The video also explains the Z-POEM technique, which involves submucosal injection, mucosal incision, and tunneling until the septum is exposed to enable a complete myotomy. The modified Z-POEM technique is described as well. The addition of mucosotomy in large Zenker's diverticulum is proposed for better closure. Other upper esophageal disorders, such as cricopharyngeal bar, can also be treated using similar techniques. The Z-bond procedure can be modified to treat various esophageal diverticuli or combination pathologies. Overall, the video presents different endoscopic approaches for treating Zenker's diverticulum and provides insights into their modifications and applications for other conditions.
