Diagnostic evaluations, including barium esophagography, chest computed tomography (CT), and endoscopy, confirmed an upper esophageal ZD (3\u2005cm in diameter).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Treatment<\/jats:title>\n                    <jats:p>The patient underwent submucosal tunneling endoscopic septum division (STESD), which is widely standardized in current literature as Zenker's peroral endoscopic myotomy (Z-POEM). Key procedural steps included mucosal incision, submucosal tunneling, complete septum myotomy, and mucosal closure using titanium clips.
