Section: Diagnosis In-depth
Certain diagnostic tests must be performed to make a definitive diagnosis of esophageal disease and exclude other disease processes that may cause similar symptoms. A complete history is especially important in these cases, as regurgitation – a common clinical sign seen with esophageal disease – is often referred to as vomiting by the pet owner. A thorough work-up begins with a broad general baseline of diagnostic tests and, in many cases, more specialized or advanced testing are indicated as well. It is important to note that an accurate diagnosis is necessary for an accurate treatment regime.
At one time or another your dog may have a bout of vomiting, usually from eating too much or too fast. Vomiting may be just a sign of a minor problem – or it could be something very serious.
Unlike vomiting, regurgitation is not accompanied by nausea and does not involve forceful abdominal contractions. It is a symptom of esophageal disease and not a disorder in itself.
Esophagitis is an inflammation of the esophagus that can occur from a variety of causes. Frequent vomiting, reflux of gastric juices or ingestion of corrosive chemicals are the most common causes.
Megaesophagus is a condition of the esophagus where there is decreased or absent movement. This can be caused by a variety of nerve or muscle diseases and most often causes regurgitation.
