Endoscopy Article


Endoscopy allows direct videographic imaging of certain internal body systems. The primary uses of endoscopy at Clyde Vet Group are to examine the upper gastrointestinal tract (oesophagus, stomach and duodenum) and the respiratory tract of larger dogs. However it can also be used to examine the lower gastrointestinal tract (colon) when required.

Although endoscopy is a minimally invasive procedure all patients have to undergo a general anaesthetic. The reason for a general anaesthetic is that unlike in human medicine our companion animal patients find conscious passage of the scope uncomfortable and distressing. All cases will be examined thoroughly by our veterinary team prior to endoscopy too ensure they are fit to undergo a general anaesthetic.

Gastroduodenoscopy is the examination of the upper gastrointestinal tract and is often used for cases of chronic vomiting and removal of some stomach foreign bodies. Small pinch samples can be taken of the oesophagus, stomach and duodenum during endoscopy and these samples can be sent for external analysis in a bid to achieve a diagnosis. Only certain foreign bodies can be removed via endoscopy due to their size and potential risk of damage to the oesophagus on the way out.

Bronchoscopy is the examination of the airways to the level of the bronchioles but is limited to larger dogs due to the diameter of the scope. Brocnchoscopy allows direct visualisation of the lungs as well as allowing bronchial alveolar lavage to achieve samples of cells deep within the lung tissue. These lavage samples are then sent to an external lab for examination and potential diagnosis.
