#'''Traction forms''' consists of all the oesophageal layers and results from peri-oesophageal inflammation and fibrosis and develop mainly in the cranial and mid-oesophageal body. Sacculations are created by adhesions to adjacent tissues.

*Small diverticula - managed by feeding bland soft or liquid diets.

*Small pulsion diverticula - should be surgically corrected as food impaction may enlarge the diverticula.

*Larger diverticula - require surgical excision and reconstruction of the wall of the oesophagus.

==Prognosis==

==Prognosis==

Fair to guarded due to post-op complications of oesophageal hypomotility and oesophageal stricture formation.
