An esophageal diverticulum is a protruding pouch in a weak portion of the esophageal lining. Previously, our team had reported an endoscopic tunneling technique (submucosal tunneling endoscopic septum division) for diverticulum treatment. However, it does not perform well for the diverticulum located in the upper esophagus, where most diverticula are located. Herein, we report a new endoscopic technique, called endoscopic transversal incision and longitudinal septostomy (TILS). TILS provides both larger operational spaces and complete septostomy and can be performed on most types of diverticula, including Zenker’s diverticulum.
