Introduction

• The oesophagus is the part of alimentary tract that tends to go wrong least often.

• Failure of oesophageal function results in obstruction and in failure of ingesta to pass to the stomach.
• In the bovine there may also be failure of eructation and tympany may develop.

Defence Mechanisms

• The oesophagus has no serosa and is covered by the fibrous tissue of the neck and mediastinum, from which it derives its blood supply.
• Consequently, infection spreads easily and healing is more difficult.
• Oesophageal disease is therefore difficult to treat and is consequently very serious.
