Standard per-oral endoscopic myotomy (Z-POEM) technique. (A) A ZD (yellow arrow Zenker’s diverticulum; blue arrow septum) is identified. (B) A mucosal bleb is created 2 cm above the septum. (C) A submucosal tunnel is created using spray coagulation and injection of saline/indigo carmine solution via the pump. Once the septum is exposed, the septotomy is performed using an endoscopic submucosal dissection knife with an insulated tip. (C–E) The septotomy is extended until the longitudinal muscle fibers of the esophagus proper are exposed (red arrow). (F) The mucosal incision is closed using through-the-scope clips
