What Is an Esophageal Diverticulum?

An esophageal diverticulum is a pouch of stretched tissue. It can develops anywhere along the esophagus. There are three types of esophageal diverticula according to their location within the esophagus (see picture below):

  • Zenker’s diverticula, the most common type of esophageal diverticula. It is usually near the top of the esophagus.
  • Midthoracic diverticula, in the mid-chest
  • Epiphrenic diverticula, above the diaphragm
