What is a gastrointestinal obstruction?
This is a complete or partial obstruction of the gastrointestinal tract anywhere from the oesophagus to the large bowel. Most commonly, they are seen in the small intestinal area as this is the narrowest area of the gastrointestinal tract. These obstructions are usually ingested foreign objects, in both younger and older dogs, but can also be cancers in older dogs. The most common age we see these problems is one to three years old.
Diagnosis methods
Proving there is an obstruction is sometimes quite simple, as the foreign object may show up readily on x-rays – for example, bones or rocks or metallic objects. Other objects such as seeds, pieces of toys, rubber, etc. are much more difficult to see on plain x-rays. Contrast such as barium is often used to improve pictures of the inside of the body produced by x-rays and help prove there is actually an obstruction.
