===Diagnostic Imaging===

===Diagnostic Imaging===

Fibrosing strictures must be differentiated from [[Vascular Ring Anomalies (Persistent Right Aortic Arch: PRAA) - WikiClinical|vascular ring anomalies]], [[Oesophagitis - WikiClinical|oesophagitis]], intraluminal and extraluminal masses. This can be done with survey and contrast radiography, endoscopy and ultrasonography.

Survey radiographs are usually unremarkable in animals with benign oesophageal strictures. Barium contrast radiography is normally diagnostic of the disorder and may demonstrate:

The suspected cause (ie.[[Oesophagitis - WikiClinical|oesophagitis]]) should be corrected first.

Oral feedings should be withdrawn in patients with severe stricture or oesophagitis. An oesophagostomy tube may be placed in these cases to provide nutritional support.
