Endoscopic examination is a useful method to assess diseases of the respiratory tract, digestive tract and urinary system in small animals. In doing so, the affected organs can be examined internally with dedicated rigid and flexible optical devices, this allows for the immediate assessment of the internal structures of an organ.
The tests are carried out under general anaesthetic, as the animals would not tolerate the procedure otherwise due to the defensive reactions of the body. The duration of anaesthesia for an endoscopic examination is usually a maximum of 30 minutes. The organs can be viewed from the inside and samples can be obtained.
