Endoscopic diverticulotomy on zenker's diverticulum with SB knife junior type endoscopic scissors. Safety profile in esophageal muco-myotomy

Abstract Text The SB knife junior endoscopic scissors are commonly used in submucosal dissections. Its small size allows for more precise cuts that can be useful in small diverticula.

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.

The use of the SB Knife junior type endoscopic scissors seems to offer an adequate safety profile for use in esophageal muco-myotomy, offering finer control given its size, being a valid alternative to perform these techniques, especially in shallow diverticulums [1] [2] [3].
