Abstract:
The Stag Beetle (SB) knife junior endoscopic scissors are commonly used in submucosal dissections. Its small size allows for more precise cuts that can be useful in diverticula with short, wide septa. In these types of septa, a Z-POEM technique may be considered, although its practicality is limited due to its complexity. We present the case of a 64-year-old man with symptoms of dysphagia, diagnosed with a 2 cm deep Zenker's diverticulum. It was therefore decided to perform an endoscopic muco-myotomy of the diverticulum.
