The three different types of the [[esophageal]] [[Diverticulum|diverticula]] are as follows Phrenoesophageal ([[Zenker's diverticulum]]-70%), [[Epiphrenic]], Thoracic and [[Mediastinum|mediastinal]].
Diverticula of the esophagus can be classified into phrenoesophageal ([[Zenker's diverticulum]]-70%), epiphrenic, [[thoracic]] and [[Mediastinum|mediastinal]].
