Flexible endoscopic Killian-Jamieson diverticulotomy and literature review (with video).

摘要

Killian-Jamieson diverticulum (KJD) protrudes through a muscular gap (Killian-Jamieson triangle) in the anterolat-eral wall of the cervical esophagus inferior to the cricophar-yngeus, superior to the circular muscle of the esophagus and lateral to the longitudinal muscle of the esophagus. KJD also has been called the "lateral cervical esophageal diverticulum" or "lateral diverticula from the pharyngoeso-phageal junction area." KJD arises inferior and lateral to Zenker's diverticulum (ZD). KJD can be bilateral in some patients. In addition, KJD and ZD can also coexist in a small number of patients.
