Abstract Submucosal tunneling endoscopic septum division (STESD) is a valid endoscopic modality for treating esophageal diverticula. However, it requires highly skilled endoscopists. Here we propose a modified STESD method. This is a single center prospective case series. We consecutively enrolled 8 patients diagnosed with esophageal diverticula. All the patients underwent the modified STESD by one experienced endoscopist.
