==Introduction==
==Description==
An oesophageal diverticulum is a circumscribed sacculation of the wall of the oesophagus. The diverticulum may be '''congenital''' or '''acquired''' and congenital diverticula usually occur due to a defect in the muscle layers of the oesophagus through which the mucosa can herniate. Acquired diverticula can be divided into traction and pulsion forms.
