==Description==
Oesophagitis in an inflammatory disorder of the oesophagus that usually involves the mucosa but can involve the deeper layers of the submucosa and muscularis. It can take the form of acute or chronic. The disease process occurs after disruption of one of the barrier defence mechanisms and can lead one or several of inflammation, ulceration and erosion of the underlying structures. The most common causes are:

===Clinical Signs===
===Clinical Signs===
include:
*regurgitation
*salivation
*neck extension during swallowing
*odynophagia
*food avoidance
*aspiration pneumonia (wheezes, coughing)
===Laboratory Tests===
===Laboratory Tests===
Generally unremarkable but may show:
*leucocytosis
*neutrophilia
===Diagnostic Imaging===
===Diagnostic Imaging===
The oesophagus is generally normal on routine survey radiographs. Signs of aspiration pneumonia may be seen in ventral lung lobes. It can be better differentiated using barium-contrast studies which may show:
*an irregular mucosal surface
*narrowing
*a dilated oesophagus
*oesophageal hypomotility
To better diagnose oesophagitis, endoscopy with biopsies can be used. Severe oesophagitis will be seen with an oedematous mucosa that is hyperaemic, ulcerated and actively bleeding, whilst less severe cases may require several mucosal biopsies to diagnose the condition.
