Modified submucosal tunnelling endoscopic septum division for symptomatic esophageal diverticula is effective and safe: a prospective case series (with video)

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.
