Single-Tunnel Z-POEM

Abstract Text This video illustrates a modified Z-POEM with creation of a single tunnel instead of two, in an effort to simplify the procedure and reduce the total duration. After the initial mucosal incision, the lifting agent is injected in both sides of the septum. A single tunnel is then created at side of the diverticulum, followed by division of the septum. The submucosal cushion at the esophageal side is maintained by repeated injections of the lifting agent. This is crucial to avoid damage of the esophageal mucosa during myotomy. At the end of the procedure the mucosotomy is closed with clips.
