Body was changed:

Oesophageal diverticula are sac or pouch projections arising from the esophagusoesophagus.

Epidemiology

They can occur in all ages but more frequent in adults and elderly people.

Pathology

Oesophageal diverticula could beare either;:

  • true diverticula: when they include all esophageal layers
  • Falsefalse diverticula: occur when they contain only mucosa and submucosa herniating through the muscular layer e(e.g. Zenker's diverticulum)

Oesophageal diverticula are classified according to the mechanism of formation into:

  • traction diverticula: occurs secondary to pulling forces on the outer aspect of the esophagusoesophagus
  • pulsion diverticula: occurs secondary to increased intraluminal pressure e(e.g. Zenker diverticulum)

Classification

they areThey can be classified according to their location into;:

Upper esophageal diverticula
Middle esophageal diverticula
  • traction diverticula: occur secondary to scarring, fibrosis and inflammatory processes in the mediastinum pulling on the esophagealoesophageal wall
  • pulsion diverticula,: are usually are false diverticula and occursoccur secondary to abnormal forces applied to an esophagealoesophageal segment
Lower esophageal diverticula
